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 and how they could be better. Lately, designing and shipping with AI tools and workflows.

Blockradar has since processed $1.3B across 1.1M transactions, with 189.3K wallets created.
