What I'm looking for

I am looking for a team where I can build production grade web apps with clean architecture, domain-driven design, and real-world problem solving especially e-commerce, agentic AI/RAG systems, and real-time data experiences shipped with strong testing.

I’m a Full Stack Software Engineer with 4+ years of experience building production web applications across e-commerce, agentic AI systems, and developer tooling. I’ve shipped multi-vendor commerce architecture, RAG knowledge pipelines, and real-time inventory systems with a strong focus on clean architecture and domain-driven design.

Recently, as a Lead Full Stack Engineer on an agentic business platform, I collaborated from concept to live deployment—building public business pages, AI chat, and canvas-driven site updates, plus real-time order/cart flows with LLM tool integration. I’m also the open-source author of a TypeScript perceptual color algorithm library (DeltaE76/94/2000), and I enjoy delivering testing-backed, policy-safe systems that solve real problems.
