Acerca de Trevis
I help businesses build fast, reliable web and mobile applications from start to finish. Whether you need a new product built from scratch, a legacy system modernized, or a mobile app launched on iOS and Android, I handle the full stack so you don't need to coordinate multiple developers.
What I deliver: production-ready web apps with Next.js and React, cross-platform mobile apps with React Native and Expo, backend APIs with Node.js and Python, cloud infrastructure on AWS, and real-time systems with WebSockets and Redis.
My typical projects include SaaS platforms, business dashboards, mobile apps, automation workflows, and e-commerce systems. I've delivered 8+ production applications across fintech, logistics, fitness, and manufacturing.
I work independently, communicate clearly, and ship tested code on schedule. Based in Barcelona, available across European time zones, fluent in English and Spanish.
