What I'm looking for

“I'm looking for a role where I can solve meaningful problems, contribute to impactful products, and grow technically—especially in areas like scalable systems, AI integration, or developer tooling. I also value strong engineering culture, clear communication, and a team that supports learning and autonomy.

I’m a full-stack software engineer with 7+ years of experience building scalable, production-grade web applications across diverse industries, including healthcare, finance, and education. I specialize in modern JavaScript frameworks (React, Node.js), backend development in Python and C#, and cloud-native architecture on AWS and Azure.
