About Me

I'm a software engineer specializing in Android development with more than seven years of professional experience. Through that time, I have had the opportunity to work as an independent consultant solo-building apps from requirements to product delivery, but also as part of large teams for mobile apps from thousands to millions of users, including video streaming, e-commerce, online fitness, time tracking, casino, and proprietary hardware apps.

As a professional, I enjoy working on challenging projects and consider myself a knowledge lover; I'm always learning new things, technologies, and best practices. People know me as someone adaptable and entirely passionate about continuous self-improvement.
