What

I do

Backend Engineering

I build the systems that power modern products — secure APIs, scalable server architecture, and reliable data layers. My primary stack is Node.js and TypeScript, with PostgreSQL and MongoDB for persistence. I design backends that are built to last: clean, well-structured, and ready to grow.

Full-Stack Development

When a project needs end-to-end ownership, I bring the same engineering rigour to the frontend. React on the client, Node.js on the server — with the architecture decisions made by someone who understands both sides of the stack.

AI Integration

I implement production-grade AI features: RAG pipelines, LLM-powered content generation, and automated moderation systems built on OpenAI APIs. Not prototypes — shipped features running in live products.

Security

Secure API design is built into how I work, not added on afterwards. Authentication, authorisation, input validation, and data protection are treated as core requirements from the start.
