Summary
🤩
Rockstar🎓
Top SchoolJuan Ross is a Senior Software Engineer with a decade of remote-first experience building user-facing applications and device communication layers, notably as Technical Lead on Ledger’s Devices Team and now at Taptap Send. He combines full-stack React and React Native expertise with deep knowledge of BLE/USB device protocols, having contributed to Ledger’s widely used Ledger Live and ledgerjs projects. A committed mentor and open-source advocate, he enjoys teaching and helping colleagues reach that “aha” moment while maintaining strong documentation and team practices. His work spans mobile UI polish, performance fixes, and low-level device integrations—sometimes threading Android exchange logic to avoid blocking the UI. Based in the Oviedo area of Spain, he pairs technical adaptability with social and environmental interests, and is open to relocation or new challenges. Unexpectedly personable for a lead engineer, he once ran a cooperative startup and still fondly remembers his dog Puerto.
