ABOUT

Bio

I'm a full-stack engineer running SajeLabs, building products end to end — from the smart contracts and back-end services to the interface that ties them together. Blockchain, back-end, front-end: one mind, the whole pitch.

Whether it's architecting a system from ground zero, shipping production Bitcoin/Ethereum infrastructure, or crafting an interface people actually enjoy, I help teams turn an idea into something live.

Roster
  • BTC-Backed Lending
  • SajeLabs
  • CryptoSwift
  • Higgsfield
  • Independent Founders
  • DeFi Protocols
  • Early-stage Startups
  • Web3 Studios
