Esther, who goes by Tassy Omah, product designer, Toronto

I’m Esther, or Tassy Omah, a product designer with six years of experience taking early-stage products from 0→1 across fintech, SaaS, Web3, and solar.

I like figuring out how things work, how they could be better, and lately, exploring how applying design taste can push the limits of designing with AI.

Blockradar

  • 2024
  • V1 design

Blockradar serves businesses that want on-chain wallets without building the infrastructure. I designed the first version in 2024 with Faye (product designer), and handed over a production-ready Figma file: scalable patterns, a responsive version, handoff notes. Blockradar has since processed millions of dollars in transactions.
