What I'm looking for

I seek roles building scalable web or AI products where I can lead architecture, improve reliability, and ship high-impact features in collaborative teams.

I am a senior full-stack engineer with a decade of experience building scalable web and mobile platforms and designing AI-powered products. I specialize in end-to-end development using JavaScript/TypeScript and Python, and I have led initiatives to modernize legacy systems and improve developer velocity.

At Itransition I led development of an AI automation workflow integrating HubSpot CRM, email tools, and Google Drive, and built an end-to-end RAG pipeline and scalable microservice/micro-frontend architecture. Previously, as a founding engineer at an edTech platform, I modernized UI with Next.js and TypeScript and improved backend scalability while maintaining backward compatibility.

I enjoy solving production stability challenges, architecting maintainable systems, and applying retrieval-augmented generation and AI agents to real user workflows. I am pragmatic, delivery-focused, and committed to bridging product needs with robust engineering solutions.
