# Igor Ganapolsky

Senior AI & Mobile Engineer. Builder of ThumbGate — pre-action defense for AI coding agents. Available for high-leverage Stripe Connect, Agentic RAG, and React Native contract engagements.

Coral Springs, FL · US Agentic RAG Stripe Connect React Native Android Claude Code · Cursor · Codex · Gemini

## What I build

ThumbGate is the agent-governance layer that turns 👍 / 👎 signals into history-aware lessons across Claude Code, Cursor, Codex, Gemini, Amp, Cline, and OpenCode. Pre-Action Checks block the next repeated mistake before the tool call runs — workflow shape, inspection evidence, token budget, and repeated-failure memory in one gate.

Outside ThumbGate, I ship production Stripe Connect marketplaces, Agentic RAG systems with LanceDB / pgvector / FAISS retrieval, React Native + Android apps, and LLM cost-instrumentation layers.
