What I'm looking for

I seek roles building scalable, type-safe web platforms with strong cloud-native practices, collaborative teams, and opportunities to lead technical modernization and mentor engineers.

I am a Full Stack Software Engineer with 4+ years building scalable web applications using Next.js, React, and TypeScript on the frontend, and Node.js, AWS Lambda, and Python on the backend. I specialize in modernizing legacy systems into cloud-native microservices, designing performant UI/UX, and implementing CI/CD pipelines and infrastructure-as-code for reliable production delivery.

I have led migrations to serverless architectures, launched MVPs from zero to production, mentored engineers, and improved product metrics such as load times, SEO, and conversion flows. I prioritize type-safe contracts, observable systems, and developer ergonomics to deliver maintainable, high-performance software at scale.
