About

I am a passionate Full-Stack Engineer with extensive experience building scalable, high-performance web applications and modern distributed systems. My background spans high-growth B2B SaaS, fintech transaction systems, and modern micro-frontends—delivering polished user experiences alongside rock-solid backend infrastructure.

Lately, I've been focused on the Generative AI frontier—architecting end-to-end Retrieval-Augmented Generation (RAG) pipelines with Node.js, PostgreSQL (pgvector), and LLM orchestration (LangChain, OpenAI) for high-accuracy semantic search, document ingestion, and context-aware conversational agents.

I thrive on turning complex system requirements into clean, type-safe TypeScript architectures—from dynamic reactive UIs with Next.js and Tailwind to optimized vector search and transactional payment workflows.
