What I'm looking for

I'm looking to build reliable, low-latency backend systems and production features, especially across distributed services, event-driven architecture, authentication, and platform infrastructure.

At HaBuild, I build production backend services that power home-screen configuration, community feeds, notifications, payments, and authentication. I shipped the UX-Service from an empty repository to production in about a week and built a rules-driven home-screen platform serving 100K+ daily users.

I've halved read latency through PostgreSQL replicas and dual-Redis caching, migrated messaging to Confluent Kafka, and improved OTP delivery with cross-channel fallback. I also strengthen security through IDOR protections and hardened JWTs, while contributing 700+ merged pull requests across 28 repositories.
