What I'm looking for

I’m looking to build high-concurrency backend systems where correctness matters. I want to own performance-critical services, automate DevOps/CI/CD, and deliver strong production observability—so reliability, speed, and scalability are measurable.

I’m a performance-focused Backend Software Engineer specializing in high-concurrency, distributed systems. I build reliable APIs with Go, Node.js/NestJS, and PostgreSQL, and I’m especially interested in eliminating race conditions using Redis distributed locking and strong transactional design.

In my recent work, I engineered and optimized core backend endpoints for HRIS and workflow automation, cutting employee onboarding processing overhead by 42% and improving system scalability. I also architected inventory transfer flows with validated multi-step schemas and implemented database-level transactional rules with Prisma to ensure 100% data integrity across 5,000+ daily concurrent stock transactions.

I’m equally driven by production readiness: DevOps automation, CI/CD pipelines, and observability. I’ve delivered RBAC-secured multi-tenant backend systems (including a 30% query-latency reduction) and built projects like TurfSync, using a dual-layer locking strategy to achieve zero double bookings under heavy load, plus monitoring with Prometheus and Grafana.
