🛠️ shipping the GitHat fleet
Builder based in NYC. I work across the full stack — from on-chain protocols to AI agents to multi-tenant SaaS — and care about shipping things that work end-to-end. The Vyper-pilled dev.
- On-chain — smart-contract development and security review across EVM and a few non-EVM chains
- AI agents — agentic workflows, retrieval, and orchestration around modern LLMs
- Fullstack web — modern frontend stacks, typed APIs, AWS-native edge
- Data / forecasting — time-series modeling and algorithmic trading research
Comfortable across several languages and ecosystems; usually picking up another. Still learning every week.
- GitHat — Identity layer for the fleet
- Sebastn — Payments rail
- ClickReserv — Multi-tenant booking SaaS
- Quantl — Quant signals + forecasting
- Colmado — Neighborhood commerce
Open-source, on-chain payments + commerce + identity layer. One shared, multi-tenant router — zero custody, USD-priced via Chainlink feeds read in-tx, exact fee-split — joined with one permissionless call. Source-verified on Base Sepolia, Ethereum + Optimism Sepolia, and Avalanche Fuji (Arc Testnet + Robinhood Chain deployed, verification pending); deployment and repo activity below refresh on each daily sync.
