About

The landscape of mobile technology is my playground and passion. For over five years, I’ve been building Android apps with a deep focus on what’s happening under the hood. I’m particularly interested in the engineering side of performance optimizing CPU usage, tightening up memory management, and ensuring that high-quality code translates into a lean, resource-efficient application. Currently, I’m an Android Engineer at Foodics, where I help build and refine mobile solutions for the F&B industry. I’m a big believer that the best apps aren’t just functional; they’re engineered to be stable and fast even under heavy load. When I’m not profiling code or hunting down memory issues, you’ll find me in the open-source community, collaborating on tools and apps that help push the limits of what mobile hardware can do.
