Eduardo KeglerSenior Frontend Engineer

I build sign-in flows and trading interfaces for crypto and fintech.

I'm a Senior Frontend Engineer with 8 years of experience, the last 5 in crypto and fintech at Coinbase, Liquid Labs and NG.cash. I own products end to end, from the RFC to the A/B test, and work on the backend when a feature needs it. I took the GTE frontend from zero to 1M+ testnet users and raised Coinbase sign-up conversion by 35%.

Open to remote contract work. Florianópolis, Brazil (UTC-3).
