Antonio Arjona is a Tech Lead based in Girona with 10 years of hands-on experience building mobile-first products and leading migrations from monoliths to microservices at scale. At N26 he progressed from Android engineer to Tech Lead, driving a standing-orders migration that cut support contacts by 50% and boosted performance 4x, while shortening feature delivery from months to weeks. He blends deep Android expertise (Kotlin, Coroutines, MVVM) with systems thinking—improving test coverage, reliability, and service performance to enable fast, safe releases. A former co-founder and long-time developer of mobility and local apps, he pairs product-minded engineering with practical architecture and team coaching. He also holds formal training in software engineering and Scrum, and brings a playful, hacker spirit evident in his GitHub persona.
