A developer at the
intersection of code & design

I'm a Full Stack Web Developer and Computer Science graduate with a passion for clean code, pixel-perfect design, and the craft of building Websites & Saas that actually converts.

From modern frontend experiences to scalable backend systems, I've helped businesses across 20+ countries build, launch, and grow digital products. With a strong Computer Science foundation, I don't just write code—I architect secure, high-performance applications designed for scalability, maintainability, and long-term success.

Focus: performance, scalability, security, and building seamless user experiences from frontend to backend.
