As a Freelance Full Stack Software Developer, I built and shipped Restaurant Coréen Luna’s production reservation platform, which processed 150+ group bookings for more than 1,000 guests with no manual charge corrections. I also moved no-show charging to background workers, cutting the admin’s p95 enqueue response from 1088ms to 212ms.

At LJYSoftware, I migrated blocking handlers to async I/O, cutting p95 latency by 60% and lifting throughput by 5x on the same instances. I also built an internal scheduling platform and closed cross-tenant data exposure risks across authenticated endpoints.
