Get Started

Off-the-shelf AI tools solve general problems. Custom AI solutions solve your specific problem — the way your business actually works, integrated with the systems your team already depends on.

At Webtech Nepal, we design and build custom AI solutions and system integrations for businesses whose needs exceed what generic SaaS tools can deliver. The organisations that gain the most durable competitive advantage from AI are not those that subscribe to the same platforms as every competitor — they are those that invest in purpose-built solutions that encode their unique processes, proprietary data, and operational context into AI systems that no competitor can replicate by signing up to the same product. Custom AI is not about building what no one else has built; it is about building exactly what your business needs, integrated precisely into how your team works, owned and controlled by you rather than a third-party vendor.

System integration is the connective tissue that makes modern technology stacks function as unified operational platforms rather than collections of disconnected tools that require manual coordination at every boundary. Most growing businesses in Nepal operate across five to fifteen different software systems — accounting, CRM, inventory, e-commerce, communication, HR, project management — with data siloed in each, duplicate entry at every handoff, and no single source of truth for the information that drives decisions. We build the integration architecture that eliminates those silos: connecting systems through APIs, building middleware layers that translate between incompatible data formats, and creating the unified data flows that let your team operate from one coherent view of your business rather than twelve separate dashboards that never agree on the same number.

We provide tailored solutions built on creativity, precision, and trust - ensuring quality results and a smooth experience every step of the way.

Fields of Expertise

We engineer custom AI solutions and system integrations that give Nepali businesses technology built precisely around their operations — not the other way around.

Custom LLM Application Development

Purpose-built applications powered by large language model APIs — OpenAI GPT-4o, Anthropic Claude, Google Gemini, and open-source models — designed around a specific business function rather than general-purpose use. We architect the prompt engineering framework, context management strategy, memory architecture, tool use configuration, and output validation layer that make LLM applications reliable in production rather than impressive in demos but inconsistent under real operational conditions with real user inputs that deviate from the training distribution.

Enterprise System Integration & API Development

Robust integration architecture connecting your business-critical systems — ERP, CRM, accounting software, e-commerce platforms, HRMS, inventory systems, and communication tools — through purpose-built APIs, middleware layers, and event-driven integration patterns that synchronise data in real time or on schedule without requiring manual re-entry at system boundaries. We design integrations that are fault-tolerant, observable, and maintainable — handling authentication, rate limiting, retry logic, schema transformation, and conflict resolution as first-class engineering concerns rather than afterthoughts.

AI Model Fine-Tuning & Custom Training

Fine-tuning of foundation models on your proprietary data — product catalogues, customer interaction histories, domain-specific terminology, internal documentation, and process knowledge — to produce models that perform significantly better on your specific tasks than general-purpose models prompted with the same information. Fine-tuning is most valuable when your use case involves highly specialised language, consistent output formatting requirements, or a task where prompt engineering alone cannot achieve the accuracy threshold your business requires for production deployment.

AI Agent & Multi-Agent System Development

Autonomous AI agent systems that plan, reason, and execute multi-step tasks with access to tools — web search, database queries, email sending, file manipulation, API calls, and code execution — completing complex workflows that require dynamic decision-making at each step rather than following a fixed automation script. We implement agent architectures using frameworks including LangChain, LlamaIndex, and custom-built orchestration layers, with human-in-the-loop oversight at configurable decision points and comprehensive audit logging of every action the agent takes on your behalf.

Legacy System Modernisation & Data Migration

Structured modernisation of legacy applications and databases that have become operational constraints — wrapping existing systems with modern APIs without requiring full replacement, migrating data from legacy formats to contemporary structures with full integrity validation, and building the integration bridges that allow old and new systems to coexist during phased transitions. For Nepali businesses running decade-old ERP implementations, Access databases, or custom-built systems that nobody fully understands anymore, we provide the technical archaeology and careful migration execution that preserves institutional data while enabling modern operational capabilities.

Custom AI Search & Recommendation Engines

Semantic search and personalised recommendation systems built on vector databases and embedding models — enabling your users to find products, documents, or knowledge base content through natural language queries that understand intent rather than requiring exact keyword matches, and surfacing personalised recommendations based on behaviour patterns, preferences, and contextual signals that rule-based recommendation engines cannot capture. For e-commerce businesses with large catalogues and for knowledge-intensive organisations with extensive document libraries, AI-powered search delivers conversion and engagement improvements that keyword search fundamentally cannot achieve.

Real-Time Data Streaming & Event-Driven Architecture

Event-driven integration architectures using message queues, webhooks, and stream processing — enabling real-time data synchronisation between systems, immediate AI model inference on incoming events, and reactive business logic that triggers automatically when specific conditions occur in your data. Event-driven architectures decouple systems from each other, eliminate the polling inefficiency of scheduled batch jobs, and make the overall technology stack more resilient to individual component failures because no single system needs to know about every other system's existence to participate in the operational data flow.

On-Premise & Private AI Deployment

Custom AI deployments on infrastructure you control — on-premise servers, private cloud environments, or air-gapped systems — for organisations with data sovereignty requirements, regulatory constraints, or confidentiality considerations that preclude sending sensitive data to third-party AI APIs. We select, configure, and deploy appropriately capable open-source models (Llama 3, Mistral, Qwen, and equivalents) on your hardware, optimise inference performance through quantisation and batching, and build the same application and integration layers we would for cloud-hosted implementations — without any data leaving your perimeter.

Industry-Specific AI Solution Development

Vertically specialised AI solutions built for the regulatory environment, data structures, workflow patterns, and performance requirements of specific industries — healthcare patient data processing, financial transaction analysis and fraud detection, educational content personalisation, logistics route optimisation, manufacturing quality control, and public sector document management. Vertical AI solutions outperform horizontal tools because the underlying models, data pipelines, and output interfaces are calibrated to the specific vocabulary, decision criteria, and compliance constraints of the domain rather than designed for the broadest possible generality.

AI Safety, Testing & Quality Assurance

Rigorous evaluation and safety testing for custom AI systems — building evaluation datasets that represent the full distribution of real inputs your system will encounter, stress-testing model behaviour under adversarial and out-of-distribution inputs, implementing output validation layers that catch and handle problematic generations before they reach users, and establishing the monitoring infrastructure that detects quality degradation in production before it accumulates into a significant operational or reputational problem. AI quality assurance is categorically different from traditional software QA; we bring the methodology appropriate to probabilistic systems rather than applying deterministic testing frameworks that miss the failure modes unique to AI.

Third-Party Platform Integration & Middleware

Custom middleware and integration layers that bridge incompatible platforms — translating between different data schemas, authentication protocols, API styles (REST, GraphQL, SOAP, EDI), and communication patterns that prevent otherwise capable systems from exchanging data reliably. We build integration middleware that is observable (every message logged and traceable), resilient (failures handled and retried without data loss), and maintainable (documented, versioned, and deployable through standard CI/CD pipelines rather than hand-configured on a single server nobody remembers how to access).

Custom AI Solution Maintenance & Evolution

Ongoing engineering support to keep custom AI systems and integrations performing at full effectiveness as your business and technology environment evolve — updating model configurations as API providers release new versions, maintaining integration endpoints as connected systems change their schemas or authentication methods, expanding system capabilities as new requirements emerge, monitoring for performance degradation or integration failures, and conducting periodic architecture reviews to ensure the system remains the right solution for the business it was built to serve as that business grows and changes over time.

Our Process

Requirements Discovery & Technical Feasibility Assessment

We begin with deep requirements discovery — understanding not just what you want to build but the business outcomes it must deliver, the constraints it must operate within, the existing systems it must connect with, and the edge cases your team encounters regularly that a generic solution would mishandle. For custom AI projects, we conduct a parallel technical feasibility assessment: evaluating whether the available AI capabilities can reliably achieve the accuracy levels your use case requires, what data is needed and whether you have it, and what the realistic implementation timeline and cost looks like compared to the value the system will deliver — giving you an honest evaluation before any development investment is committed.

Architecture Design & Technology Selection

We design the complete system architecture — specifying the AI model selection and configuration, integration topology, data flow design, authentication and authorisation scheme, error handling and retry strategy, observability infrastructure, deployment environment, and scalability approach — before writing any implementation code. For system integrations, we produce integration maps that document every data exchange between connected systems including field mappings, transformation logic, event triggers, and conflict resolution rules. Architecture documents are shared with your technical stakeholders for review and sign-off, creating a shared blueprint that prevents misaligned expectations from surfacing late in the implementation cycle when they are most expensive to resolve.

Proof of Concept & Risk Validation

For novel AI capabilities or high-complexity integration scenarios, we build a targeted proof of concept against the highest-risk technical assumptions before committing to full implementation — testing whether the AI approach produces the output quality your use case requires on representative samples of your real data, validating that connected systems behave as their documentation claims under the specific integration patterns we plan to use, and surfacing unexpected constraints or compatibility issues in a low-cost exploration phase rather than discovering them mid-implementation when rework is significantly more expensive. Proof of concept findings directly inform and refine the architecture document before development begins at full velocity.

Iterative Development & Continuous Integration

We build custom systems in focused development sprints with working software demonstrable at the end of every cycle — giving you continuous visibility into progress rather than a single delivery at the end of a long waterfall timeline. Code is written to production standards from the first sprint: peer-reviewed, unit-tested, version-controlled, and deployed through automated CI/CD pipelines to a staging environment that mirrors production. For AI components, each sprint includes evaluation runs against your benchmark test set so accuracy metrics are tracked as the system evolves rather than measured for the first time at the end of development when changes are most disruptive to make.

Integration Testing & End-to-End Validation

We conduct comprehensive integration testing across all connected systems — executing the complete data flows the production system will handle, validating outputs at every stage of processing, simulating failure conditions to confirm error handling and recovery logic functions correctly, and running load tests to verify performance holds under realistic concurrent usage volumes. For AI systems, we validate against the full evaluation benchmark and specifically test the edge cases, adversarial inputs, and out-of-distribution scenarios identified during requirements discovery — because AI systems fail in qualitatively different ways than traditional software, and those failure modes must be understood and handled before real users encounter them in production.

Production Deployment & Operational Handover

We deploy to production through automated pipelines with zero-downtime deployment strategies — activating monitoring, alerting, and logging from the first live request. Alongside deployment we deliver complete system documentation: architecture diagrams, API reference documentation, data flow maps, operational runbooks for common maintenance tasks and failure scenarios, configuration management guides, and vendor contact and escalation procedures for every third-party component in the system. We conduct structured knowledge transfer sessions with your technical team and, where relevant, end-user training for the interfaces they will interact with daily — ensuring the system is genuinely owned and operable by your organisation rather than dependent on our continued involvement for routine function.

Post-Launch Support, Monitoring & Continuous Evolution

We provide structured post-launch support covering production monitoring, incident response, performance optimisation, and planned feature expansion — with defined SLAs and escalation paths that give your team confidence that critical systems are backed by engineering expertise when issues arise outside normal business hours. Quarterly architecture reviews assess how the system is performing against its original objectives, evaluate whether the technology choices made at design time remain the right ones as capabilities and costs evolve, identify new integration opportunities as additional systems are adopted, and plan the next capability expansion cycle based on accumulated operational experience with how real users and real data actually interact with the system you built together.
