About

I am a software engineer with 5+ years of experience building and maintaining complex systems across ecommerce, trade engines, booking platforms, and LMS products. My strongest focus is architecture and system design for software that can evolve cleanly over time.

I care deeply about modularity, clean code, and disciplined engineering practices. I enforce quality through static analyzers and code formatters, and I advocate automated testing whenever possible, with TDD as a preferred approach when it fits the problem.
