Who I Am
Backend developer with 3+ years shipping production systems used by millions. Currently at CODE.ID owning the REST APIs powering MyTelkomsel— one of Indonesia's largest telco super apps — with full responsibility over reliability, API contracts, and performance.
Previously cut data processing time by ~20% through ORM profiling and query optimization, and engineered a centralized platform integrating 4 communication channels including Asterisk PBX and WhatsApp Business API. I care about clean architecture not as an ideal, but as a practice that keeps production systems maintainable at scale.
