What I'm looking for

I’m looking for a backend role where I can build high-performance concurrent systems and ship LLM-integrated automation. I want ownership over scalable architecture, clean APIs, and production-grade engineering with strong engineering feedback.

I’m a Backend Engineer focused on building scalable, concurrent systems and AI-integrated applications. I work on backend services in Go (Gin), designing production-grade service layers and data flows, and I integrate LLMs into backend workflows for task execution and decision support.

I’ve built real-time, production-oriented systems like a multithreaded chat server with TLS-secured communication (X.509 PKI), custom application-layer protocol design, and a thread-pool concurrency model with backpressure. I also developed an LLM-powered chatbot service bridging Java real-time chat and Python-based AI processing, along with a microservices-based LLM automation platform featuring agent-driven architecture, ingestion pipelines, and production practices like logging, error handling, and extensibility.
