Full-stack engineer
who lives in Rust.

I build on Solana - designing on-chain protocols in Anchor with a real command of Rust's ownership model, async, and the idiomatic patterns that keep systems safe under load. I've taken protocols all the way from smart contract to live production, not just to a demo.

Beyond the chain I work across the whole stack: backends in Rust / Axum, frontends in Next.js and TypeScript, and the deploy pipelines that ship them. Most recently I built OpenBounty - a trustless GitHub bounty platform that pays contributors on-chain the moment their pull request merges.

Always up for ambitious Rust and web3 work - find me on GitHub.

OpenBounty ● live · devnet
Trustless GitHub bounties on Solana

Post a crypto reward on any open GitHub issue. Funds lock in an on-chain escrow PDA and release automatically to the contributor whose pull request merges, with no manual review and no custodian. A Rust polling service watches the GitHub GraphQL API for merged PRs and triggers winner selection on-chain.

BulkPay ● live
One-click mass payments on Solana

A bulk payment protocol that lets crypto teams send payouts to hundreds of wallets in a single transaction, with automatic scheduling for recurring payments. Built as a Rust + TypeScript monorepo with the on-chain program handling batched transfers and the scheduler driving payroll-style runs.
