I'm a Full Stack Developer with over 2 years of hands-on experience building end-to-end web applications and scalable software solutions using JavaScript and Python.
I have a degree in Computer Systems Engineering, and I've worked on a wide range of projects — helping startups, small businesses, and individuals bring their ideas to life. So far, I've delivered 50+ projects for 40+ clients, each one tailored to fit their specific needs.
I specialize in designing and building both server-side and client-side solutions using modern technologies like React.js, Next.js, Node.js, Django, and FastAPI. At the core, I enjoy creating apps that feel great to use and actually solve problems — for both end-users and the businesses behind them.
