What I'm looking for

I’m looking to build performance-critical backend systems where correctness under concurrency matters. I want to own distributed locking, database integrity, and scalable APIs—while driving CI/CD, observability, and DevOps automation in production.

I’m a Backend Software Engineer focused on high-concurrency, distributed systems—building reliable APIs with Go and Node.js/NestJS. I’m especially interested in eliminating race conditions and improving database architecture, using Redis distributed locking and carefully designed transactional rules.

In my current role, I’ve engineered and optimized core HRIS and workflow automation endpoints, cutting onboarding processing overhead by 42% and improving end-to-end API scalability. I also architected inventory transfer backends with validated multi-step schemas and enforced strict database-level transactional integrity for 5,000+ concurrent daily transactions.

I thrive where performance, security, and operations meet. I’ve reduced query latency by 30% through SQL/schema optimization and built RBAC using caching middleware; on the DevOps side, I prioritize CI/CD, production observability, Dockerized environments, and monitoring (Prometheus/Grafana). I also enjoy applying ML workflows through real-time sign recognition projects using YOLOv8 and OpenCV.
