CS student building AI agent tooling and Strict-DRY monorepos. I look for creative angles on problems other people have already written off as solved.

- Agent tooling, not toy demos.
ebay-mcpships an open-source local MCP server with 325 tools spanning eBay's Sell APIs — inventory, fulfillment, marketing, analytics, developer tooling. - Validators that catch problems before deploy.
fresh-squeezycross-checks Lemon Squeezy integrations for mode mismatches, ownership drift, and missing webhook events the official SDK doesn't track yet. - Strict-DRY by default. Monorepos, shared packages, one source of truth per behavior. Wrong abstractions are worse than a second obvious copy.
- Personal AI toolkits.
universal-agent-toolkit— production-hardened hooks, rules, skills, and agents.
- Open University of Israel — B.Sc. Computer Science (expected 2029).
- Day-to-day: shipping agentic systems and the tooling that makes them safe to ship.
