ABOUT ME

Full-stack Developer and Architect

Throughout my career, I have extensively worked with a broad range of programming languages and platforms, including Dart(Flutter), JS Frontend(React, Vue, Angular), JS Backend(Nest, Express, Node), PHP(Laravel), Java(Spring).

My experience in developing user-centric software, enhancing user experiences, and solving scalability challenges will be invaluable in driving your projects forward. I thrive in dynamic, fast-paced environments, and am adept at managing multiple priorities simultaneously.
