Product Developer @Lumel

About

Backend Engineer with 5+ years of experience building distributed systems, high-performance data pipelines, and AI-powered backends. I specialize in designing scalable microservices in Go, engineering ETL pipelines for large-scale data workloads, and integrating LLM-based AI systems into production. I enjoy working close to the infrastructure layer — concurrency, distributed locking, session management, observability — while also shipping product features end to end. Recently expanded into AI engineering — RAG pipelines, vector search, and LLM APIs — building systems where retrieval precision and response quality actually matter. Stack: Go · TypeScript · Node.js · gRPC · REST · DuckDB · Redis · SQL · Kubernetes · AWS · Fabric · Qdrant · OpenAI · Anthropic
