01 — About

Reliable systems,where backend depth meets applied AI.

I'm a backend, full-stack and AI engineer with 6+ years shipping production software for enterprise clients. My work spans the whole stack, but I'm most at home in the backend: service architecture, message queues, and the data layer that keeps things fast at scale.

Lately I focus on applied AI - agentic workflows, semantic search, and retrieval-augmented generation. I care about clean APIs, observable systems, and shipping things people actually use.

Work with me

I handle the full picture - frontend, backend, AI, database, deployment. Whether you need a product built from scratch or an engineer to strengthen your team, I ship production-ready code.

01

Full-stack product builds.

Take your idea from design to a deployed, production-ready product. I handle the frontend, backend, database, auth, payments and infrastructure so you ship faster with one engineer instead of three.

02

AI features in your product.

Add chat with your data, smart search, document Q&A or AI agents that actually work on your real company data - built into your existing product, not a standalone demo.

03

Scale and improve what you have.

Fix slow APIs, untangle messy architecture, migrate to microservices, set up CI/CD, or integrate third-party services. I dig into what you already have and make it better.

Fixed-scope project

Clear deliverables, fixed quote.

Monthly retainer

Ongoing development and support.

Technical audit / consultation

Architecture review, AI feasibility, or code review.
