I’m a back-end developer who builds scalable services with Go and TypeScript, and I’m obsessed with performance, reliability, and maintainable architecture. I apply Clean Architecture, dependency injection, and strong API design to deliver systems that stay fast under load.

In my recent work, I optimized API performance—reducing average response latency by 25% and offloading 20% of database traffic. I improved search and query speed using PostgreSQL indexing/query tuning, added a Redis caching layer, and integrated Elasticsearch for fast full-text search.

I also designed and implemented a scalable Express.js/TypeScript enterprise web server with 85%+ coverage on critical auth flows. By using type-safe Prisma access, secure RBAC/JWT middleware, and Clean Architecture, I eliminated a class of runtime database query errors.

Beyond core back-end, I’ve built end-to-end solutions: WordPress administration automation (99.9% uptime, 85% fewer formatting errors) and multi-service AI/recommendation pipelines. I enjoy turning complex requirements into clean, testable components—whether it’s gRPC event systems with RabbitMQ or asynchronous AI assistant workflows.
