Available for New Roles (Barcelona & Remote)

Building Reliable Product Systems From 0 to 1

I am a Senior Front-End & Cross-Platform Engineer with 3+ years of experience crafting high-performance web applications, mobile identity wallets, design systems, and multi-language SDKs.

Based in Barcelona, Spain. Over my career, I've specialized in turning complex technical challenges into clean, accessible, and performant user experiences. As the sole Front-End Engineer at Didit, I led the frontend architecture from day one—working directly with the CTO and Lead Designer to ship our B2B Enterprise Console, KYC Client App, React Design System (`diditui`), iOS/Android mobile wallet, and developer SDKs across 5 platforms.
