JMES World

Head of engineering & protocol architecture

Cosmos chainDAO protocol for art tokenization, Berlin
Overview

JMES World is a decentralized art ecosystem founded by Udo Schloemer, the entrepreneur behind Factory Berlin, one of Europe’s most prominent startup campuses. I served as Head of Engineering, bootstrapping the entire technical stack from zero. The centrepiece was a dedicated P2P blockchain protocol built on the Cosmos SDK with Tendermint consensus, powering a native JMES token, an on-chain identity system and a DAO governance layer that let the community fund and direct real-world art businesses from the chain. On top of that sat a tokenization model for physical artworks (including pieces by Warhol) designed to comply with European securities regulations, and a React Native mobile application that served as both investor prototype and developer foundation. The engagement covered engineering roadmap, infrastructure (AWS/Docker), token economics, yellow paper authorship and the full set of Web3 connectivity libraries.

What I did
  • Built the JMES protocol from scratch (Go, Cosmos-SDK, Tendermint)
  • DAO governance, on-chain identity and funding system
  • EU-compliant art tokenization model (Warhol, contemporary art)
  • React Native mobile app and Web3 connectivity libraries
