What I'm looking for

I seek roles where I can own end-to-end features, collaborate closely with founders/product teams, integrate AI, and deliver pragmatic, high-impact solutions quickly.

I am a Full Stack Engineer with eight years building and shipping web and mobile applications across startups, agencies, and regulated environments. I specialize in React, Next.js, TypeScript, Node.js, and PostgreSQL, and I own features end-to-end from vague requirements through production deployment.

I have delivered multiple MVPs and internal platforms that cut operational overhead by up to 45%, improved data accuracy by 30%+, and sped feature delivery cycles by 40% through improved architecture and tooling. I lead pragmatic engineering in ambiguous environments, shipping fast 80% solutions and iterating from real user feedback.

I have hands-on experience integrating AI and LLM-powered features into products, optimizing performance and reliability on AWS, and establishing CI, automated testing, and deployment workflows that reduce regressions and rollbacks. I collaborate directly with founders and cross-functional stakeholders to translate business needs into reliable software.
