What I'm looking for

I seek roles where I can lead AI-augmented engineering, build scalable full-stack products, mentor teams, and drive fast, secure delivery in a collaborative, growth-oriented environment.

I am a founder and senior full-stack developer with 9+ years of experience building scalable web and mobile ecosystems, shifting to AI-augmented development using autonomous agents to accelerate delivery. I design and deliver production-ready applications with Next.js, Node.js, PostgreSQL/Supabase, React Native, and RAG architectures (LangChain, ChromaDB) while ensuring security-by-design and strong Core Web Vitals performance.

I have led teams, consulted with stakeholders, and built full product stacks including marketing sites, embedded RAG sales agents, and autonomous ETL pipelines. My work emphasizes maintainability, scalability, fast time-to-market, and measurable results such as automated lead capture, sub-30s discovery-to-publish, and fully paperless contract workflows.
