Hi, I'm Andrei

Rust Performance Engineer | AI Tooling Architect

I build high-performance systems that solve real problems. My work spans from SIMD-accelerated parsers to AI agent infrastructure—always with a focus on measurable impact.

Open Source Contributions

Core contributor to foundational AI infrastructure:

| Project | Contributions | | | --------- | --------------- | :-: | | modelcontextprotocol/rust-sdk | Elicitation support, context-aware completion | | | restatedev/restate | Shell completion for restatectl | | | zed-industries/extensions | Deps extension | |

AI Agent Infrastructure

[!NOTE] Tools that make AI agents cheaper and smarter.

| Project | What it does | Impact | | | --------- | -------------- | -------- | :-: | | mcp-execution | MCP servers → standalone TypeScript tools | 98% token savings | | | claude-plugins | 8 specialized Rust agents for Claude Code | Full dev lifecycle coverage | | | mcpls | MCP ↔ LSP bridge | Semantic code intelligence for AI | | | pjs | Priority JSON Streaming + SIMD | 6x faster than standard parsers | | | tap-mcp-bridge | Visa TAP + MCP integration | Secure payment auth for AI agents | |

[!TIP] Start with mcp-execution it's the foundation for token-efficient AI workflows.

High-Performance Parsers

[!NOTE] When standard libraries aren't fast enough.

| Project | What it does | Impact | | | --------- | -------------- | -------- | :-: | | exarch | Memory-safe archive extraction, TAR/ZIP | Zero CVEs · replaces vulnerable libs | | | fast-yaml | YAML 1.2.2, zero unsafe, built-in linter | 14x faster than PyYAML | | | feedparser-rs | RSS/Atom/JSON Feed + all extensions | 213 MB/s · 94x faster | | | pyhdb-rs | SAP HANA driver with Arrow + async | Polars/pandas integration | | | scrape-rs | HTML parsing + CSS selectors, SIMD | 50x faster than BeautifulSoup | |

[!IMPORTANT] All have Python bindings — drop-in replacements for existing code. exarch, fast-yaml, feedparser-rs, and scrape-rs also have Node.js bindings.

Developer Tools

[!NOTE] Tools I wish existed.

| Project | What it does | Impact | | | --------- | -------------- | -------- | :-: | | deps-lsp | Universal dependency management LSP | Cargo + npm + PyPI | | | deps-zed | Zed extension for deps-lsp | Version hints + diagnostics | | | helix-trainer | FSRS spaced repetition for Helix | 30% fewer reviews than Anki | |

Archive

[!NOTE] Completed projects no longer in active development.

| Project | What it was | | | --------- | ------------- | :-: | | vkteams-bot | VK Teams Bot ecosystem: CLI + MCP + vector storage | | | vkteams-bot-clj | VK Teams Bot implementation | |

Building infrastructure for AI agents that doesn't waste context on ceremony.
