About

I completed a 4 year MCompSci at Oxford in 2016. I then worked as a software developer at a small biometric security company, and have since moved to developing analysis software for microscopy. I try to develop my understanding of both low level implementation details and high level conceptual constraints and opportunities.

Beyond tech, I enjoy casual debate, science, philosophy and theology.
