Backend-first. Reliability-focused.

I focus on performance, reliability, and clean system design. Shipping features matters — but making sure they hold up under real-world load matters more.

I build secure authentication, multi-tenant systems, and automation services where correctness matters: rate limits, token rules, RBAC, and clean error handling.
