closs837/README.md

Cristopher Closs

Backend engineer. I build Optics — independent lending tooling for builders on Ink. The workspace itself is open: closs837/optics.

Most of my day is TypeScript and Rust, with Python for the pipelines around them: services that have to stay up, crawlers that have to be polite, and data that has to be boring.

  • 🔭 Currently working on read-only chain tooling for optics.ink
  • 🛠️ TypeScript · Rust · Python · C#/C++ left over from university
  • 🧪 Side projects in RL and NLP: Gale, Helsinki-NLP, CypherCNN
  • 📬 Say hi: optics.ink · London

Selected repositories
