AI Engineer. 10+ years across frontend, backend, and ML tooling — currently at Comet ML on Opik, keeping LLMs honest with traces, evals, and a healthy dose of skepticism.

| Project | What it is | |
|---|---|---|
| notion-mcp-server | Production MCP server for Notion. Full read/write for AI assistants — no hand-rolled wrappers required. | ⭐ 149 |
| replicate-flux-mcp | Replicate's Flux as an MCP — your IDE generates images and SVGs without leaving the editor. | ⭐ 99 |
| gsc-cli | LLM-friendly TypeScript CLI and SDK for Google Search Console. JSON in, JSON out, agents happy. | |
| yaroslavboiko.com | Personal site and technical blog. Astro · Cloudflare Workers · a Three.js scene that earns its bytes. |
- Stop Using Claude Code on Defaults — five settings I changed in
~/.claude/settings.jsonto save tokens and stop approvinglsfor the 400th time. - Agentic UX Primitives — streaming, HITL gates, reasoning traces, confidence indicators: the frontend patterns behind products like Cursor and Claude.
- Context Engineering Ate Prompt Engineering — what's replacing prompt engineering, and how it separates AI-augmented developers from AI-dependent ones.
- The Vibe Coding Reckoning — 92% of devs use AI daily, 41% of code is AI-generated, and the backlash has arrived.

- MCP-native. Author of
notion-mcp-server(149⭐) andreplicate-flux-mcp(99⭐). TypeScript MCPs are my default surface for anything agents need to touch. - SDKs over frameworks. Anthropic and OpenAI directly. LangChain hides what you actually need to control once you ship past a demo.
- Evals as a habit. Every agent feature ships with traces and offline evals via Opik. "LGTM in chat" is not a gate.
- Stream everything. Tokens over SSE, JSON-schema-validated outputs (not regex), HITL gates wherever a mistake costs more than a click — more on this.
- Context engineering > prompt engineering. Tight working sets, retrieval that earns its tokens, system prompts treated as code — more.
- TypeScript end to end (Python when eval pipelines call for it). Node + Postgres for state.
pgvectorwhen embeddings belong next to the data. - Edge-first infra. Cloudflare Workers for latency, Astro for content, React for apps, Three.js when interactivity earns the weight.

Open to interesting problems in MCP, agent infrastructure, and AI-augmented developer tooling. If you're building something in that space — say hi.
