Senior Backend Engineer · Node.js / TypeScript
I build and operate the LLM/agent layer of distributed systems — NestJS microservices, Kafka, gRPC, and MCP servers.
🇺🇦 Lviv, Ukraine · open to EU-remote (B2B) roles
- 🔭 Currently — building agentic tooling and event-driven backends on a NestJS / Kafka / TimescaleDB stack
- ⚙️ Selected results — 10× Kafka-consumer throughput (30 → 300+ msg/s) · 70% lower DB load via multi-level caching · 10,000+ GPS events/day at 99.5% uptime · 31+ microservices wired with gRPC / Protobuf
- 🧠 Going deep on — MCP servers & agent tooling, RAG, structured outputs, evals & guardrails
