01 — About

The Engineer
behind
the code

I'm a backend engineer who genuinely loves the craft. My focus is Laravel & PHP 8+, but I think at the systems level — about schema design, API contracts, query efficiency, and production reliability.

At UniAthena, I built APIs powering 50,000+ learners worldwide, improved response times by ~20%, and shipped consistent bi-weekly releases. At ExtraazPOS, I led the backend for 3 restaurant tech products handling high-volume concurrent transactions.

I care deeply about the details that most engineers overlook — indexing strategies, payment webhook reliability, N+1 query elimination, and clean API contracts that frontend teams actually enjoy working with.
