About

I’m a self-taught programmer and currently a Senior Software Engineer at Visa. Before this, I spent 4 years at Oracle as a Software Developer, where I strengthened my foundations in backend engineering, system architecture and building reliable, scalable services. I’m passionate about problem-solving, diving deep into server-side technologies and taking on real-world engineering challenges. Whether it’s optimizing performance or experimenting with side projects, I love learning, building and constantly pushing the limits of what I can create.
