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 — 30+ merged PRs in top TypeScript/AI-tooling repos, repeat contributor in 4 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)
Active contributor to TypeScript / AI-tooling projects — sorted by merge depth, not just stars. The repeat merges are the part I'm proudest of: maintainers keep taking my PRs, not just the first one.

I don't farm PRs across dozens of repos. I go back to the same ones after a merge and find the next real bug there — that's why 4 repos above have repeated merges instead of a single drive-by fix.
- Every PR ships with a root-cause writeup, a regression test verified against the unfixed code (not just green CI), and a negative control
- No hallucinated claims about how someone else's system behaves — if I'm not sure, I say so or go check
- When a maintainer asks for changes, I re-review the whole diff, not just the line they pointed at
- Result: maintainers respond in kind — same-day merges, "Awesome, thanks for your contribution!" instead of silence
Earlier projects before shifting focus to AI systems:
- Built apps interacting with Solana blockchain (Web3.js, RPC, transactions)
- DEX integrations: Raydium, Orca, Meteora, Phoenix, Openbook, Lifinity
- On-chain arbitrage bot with Jito MEV bundle submission and 3-hop route discovery
- Real-time wallet & transaction monitoring with Telegram alerts
