Products, not just code.
I'm a Full Stack AI Engineer with two years shipping production SaaS — not prototypes. I own features from schema to screen: retrieval pipelines over pgvector, LLM providers swapped at runtime, Socket.IO and queue-backed services that stay responsive under load, wrapped in Next.js front ends people actually enjoy using.
At Enigmatix I spent two years on backend microservices, third-party platform integrations and React dashboards for apps under heavy production traffic. Most recently I worked on PayOn's restaurant POS frontend. Alongside client work I design and ship my own products — VectaJob is the largest, a full RAG platform I built and run myself.
AI product engineering
01RAG over your own data: embeddings, pgvector retrieval, GPT-4 or DeepSeek generation, with provider switching so you're never locked to one model.
Backend & real-time systems
02Node and TypeScript microservices, REST and GraphQL, Socket.IO channels, RabbitMQ and BullMQ queues, auth, storage and billing wired end to end.
Product front ends
03Next.js and React interfaces — dashboards, analytics, live API views — fast, accessible and built to survive real feature growth.
02 — Selected work
Things I've shipped.
Six products across client work and my own — architecture, API, interface and deploy.
PayOn
Restaurant POS platform
Frontend · 2026
Point-of-sale platform for restaurants. I worked on the customer-facing side, including the QR-scan flow diners use to open a venue's menu and order from their own phone.

Frontend Developer
- Triaged and fixed bugs across the client-facing side of a restaurant POS platform, working from audit findings and QA tickets rather than shipping new features.
- Integrated REST APIs into existing React views, wiring live data into screens that had been running on static placeholders.
- Optimised UI and UX: responsive layout fixes, loading and empty states, form validation and accessibility passes.
