AI & RAG Systems
Retrieval-augmented assistants grounded in your documents: ingestion pipelines, pgvector retrieval, LLM integration with provider fallback, and evaluation you can measure.
Services
Hire Fredrick Onyango — full-stack, backend & AI engineering
Kenya-based engineer building intelligent, scalable products: Kilele Archade, a live AI learning platform at kilelearchade.co.ke, and Apex, a PropTech platform. Available for product builds, freelance contracts and remote roles worldwide.

What I deliver
Engineering services
Six service lines — every one backed by production software you can try or read on GitHub, not slideware.
Full-Stack Web Products
End-to-end product delivery with React/TypeScript frontends and Node.js or Spring Boot backends — from database schema to deployed, production-ready software.
Backend APIs & Integrations
REST APIs, third-party service integration, authentication and role-based access, payment and communication workflows built to stay maintainable.
Database & Data Platform Design
PostgreSQL-first data modelling: schemas, row-level security, migrations, and pgvector embeddings kept next to the relational data they describe.
Cloud Deployment & DevOps
Dockerised deployments, CI/CD pipelines, hosting setup on Vercel/Render/Cloudflare and monitoring so releases are boring instead of dramatic.
Technical Product Building
Founder experience taking ideas to live products (Kilele Archade, Apex): scoping, architecture decisions and shipping the first version yourself.
Working together
My operating principles: understand the real problem before writing code, design the architecture first, ship working software, then improve it continuously. You get direct communication with the engineer building your product — no handoff layers.
- Understand the real problem before writing any code.
- Design the architecture first — the implementation follows the design.
- Ship working software, then improve it continuously.
- Prove capability with products and code, not claims.
Product build
End-to-end delivery — scope, architecture, build and launch of a first production version, the way I shipped Kilele Archade and Apex.
Freelance / contract
Backend features, AI and RAG integrations, or frontend work delivered inside your existing codebase and process.
Remote role
Full-stack, backend or AI/ML engineering for teams hiring from Kenya or working globally remote.
