I’m a full-stack engineer with over ten years of experience building digital products, scalable platforms, and user-focused applications.
More recently, my work has focused on artificial intelligence, real-time systems, and building products that turn emerging technologies into practical solutions. I’m also pursuing studies in Applied Artificial Intelligence, expanding how I approach automation, intelligent experiences, and complex product challenges.
Accessibility remains an important part of how I build software. I believe the web should be usable by everyone, and I aim to create products that are not only intelligent and capable, but also inclusive, intuitive, and genuinely useful.
I enjoy working at the intersection of engineering, product, and emerging technology—taking complex ideas and turning them into thoughtful experiences that solve real problems.
