At Kaapo, I designed and built payment integration endpoints and ledger transaction workflows in Node.js and Express.js. I optimized database queries and added application-level caching, bringing p99 API response latency down from 450ms to 290ms.
At Loubby AI / DivVerse, I built the event-driven core of an in-app task management and notification system. I also automated candidate processing with Redis-backed queues, cutting onboarding turnaround from several days to under 24 hours.
On my Hybrid Kubernetes Platform & Rust Gateway project, I moved staging and development workloads to a hybrid self-managed cluster and rebuilt the primary API gateway in Rust on Pingora. I propagated W3C trace context through downstream async workers, cutting the time to trace cross-service failures from 30 minutes to under 10.
