About Me✨
I’m a software engineer who designs and ships full-stack products that stay fast, clear, and reliable.
I move from React/Next.js interfaces to Flask and PostgreSQL services, balancing clean architecture with pragmatic delivery.
Outside of coding, you’ll find me lifting, playing basketball, or solving puzzles—always chasing the next challenge.
