What I'm looking for

I seek roles that leverage my graphics and systems expertise, emphasize performance optimization and CI/CD practices, and offer mentorship and growth opportunities.

I’m a software developer driven by a passion for building systems that solve real problems and push performance boundaries. I love turning complex ideas into efficient, scalable solutions — whether that’s optimizing GPU pipelines for real-time ray tracing or architecting backend services that run smoothly under load.

I’ve built projects ranging from high-performance rendering engines using Vulkan and C++, to neural networks utilising CUDA. Each project reflects my focus on precision, problem-solving, and delivering results that matter.

Beyond code, I value leadership and collaboration — whether guiding a 40-person robotics team to competition success or contributing to developer communities through competitive programming. I’m motivated by curiosity, a drive to build, and a commitment to constantly improve the systems I create.
