Design Engineer — I turn product decisions into interfaces that convert.
10+ years building production-grade interfaces at the intersection of engineering precision and product thinking. Currently at @cobrefacil, shipping billing and payment infrastructure used by thousands of Brazilian businesses.
I care about the details most engineers skip: the empty states, the error messages that actually tell you what to fix, the CTA that stays visible when you scroll. Those decisions move metrics.
Two results I'm proud of:
- Redesigned a mobile webinar experience → 45% reduction in abandonment
- Rebuilt a payment checkout UI → +22% conversion rate in production
