6+ years in distributed systems · building AI-native architecture
🌍 Open to remote opportunities — backend, AI systems, agent infrastructure
- Core stack: Node.js · TypeScript · NestJS · Go · AWS
- Built and scaled microservices in production — 40+ services (Fintech) and 98-service clinical data lake (Life Sciences)
- Deep AWS experience: Lambda, ECS, SQS, S3, API Gateway, Secrets Manager, CodeBuild
- Event-driven architecture: Kafka · RabbitMQ · Redis Streams
- Actively building AI agent infrastructure — multi-agent runtimes, LLM orchestration, MCP servers
- MSc thesis: Gamma — a browser-native multi-agent runtime system (NestJS microkernel + Redis Streams Memory Bus)
- Open-source contributor — 40+ merged PRs in top TypeScript/AI-tooling repos, repeat contributor in 5 of them
What I actually use and build with:
| Tool / Technology | How I use it |
|---|---|
| Anthropic Claude API | Agent reasoning, orchestration, code generation, multi-turn pipelines |
| OpenAI API (GPT-4) | Multi-provider gateway, fallback routing, embeddings |
| Google Gemini API | Vision, classification, real-time narration (gemini-2.0-flash) |
| Model Context Protocol (MCP) | Building MCP servers for external services (Monobank, Viber, etc.) |
| RAG + pgvector | Semantic search pipelines over custom knowledge bases |
| Ollama / Llama 3 / Qwen | Local inference, offline agent loops, cost-free experimentation |
| Multi-agent architecture | Hierarchical agent systems with lifecycle management, inter-agent bus |
| SSE + WebSocket streaming | Real-time LLM token delivery to clients |
Personal AI Projects — MCP servers (TypeScript):
- monobank-mcp — MCP server for Monobank Open API: accounts, statements, exchange rates, webhooks, Corporate API
- liqpay-mcp — MCP server for LiqPay, Ukraine's leading payment platform (PrivatBank)
- viber-mcp — MCP server for Viber messenger (Rakuten Viber Bot API)
