About Me.

I focus on building reliable, maintainable systems that handle real-world complexity.

Working in a small engineering environment gave me substantial ownership of production systems. Maintaining APIs, IoT integrations, and payment workflows taught me to consider reliability, debugging, data consistency, and deployment together. I value collaboration, code reviews, and mentorship, and want to keep growing through diverse teams and projects.

Competitive programming strengthened my problem-solving foundation, including four ICPC Asia Preliminary rounds. I look forward to learning from experienced engineers and contributing to a team. Outside engineering, I enjoy photography and have helped coordinate film and photography club events.
