Sebastian Sinatra
Interaction Developer at POAP - The Proof of Attendance Protocol
Argentina
Summary
👤
SeniorSebastian Sinatra is an interaction developer based in Argentina with nearly two decades of hands-on experience building interactive products and systems and nine years of focused professional experience across front-end, mobile, and Web3 projects. He has led UI teams and shipping-critical features at scale—from founding UI work and team leadership at White Prompt to leading frontend efforts at Despegar and contributing to POAP’s product and blockchain integrations. Sebastian blends pragmatic full-stack skills (React, React Native, Node.js, modern CSS) with product-minded UX and team coaching, handling estimations, hiring, and delivery. He’s comfortable moving between prototyping and production, having owned UI from zero to a live co-participation financing platform and later designing Web3 user experiences. Notably, his trajectory shows a steady shift from traditional full-stack roles into interaction design and blockchain-native products, reflecting both technical depth and an appetite for emerging platforms.
