What I'm looking for

I seek senior engineering roles building scalable SaaS products where I can drive performance, lead re-architecture, integrate AI features, and work in collaborative, fast-paced teams with strong engineering practices.

I am a creative, results-driven Senior Full-Stack Engineer with 7+ years building scalable SaaS platforms, dynamic frontends, and robust APIs. I specialize in React, Vue, TypeScript, Node.js and AWS, and I focus on user-centric solutions, performance optimization, and delivering measurable business results.

I have led re-architecture efforts, implemented AI-driven MVP features, integrated high-impact APIs (OpenAI, Google Calendar), and improved performance by up to 30%. I bring strong development practices (TDD, CI/CD), DevOps tooling, and a track record of improving team collaboration and accelerating delivery.
