About
Software engineer with broad experience in multiple industries from Finance, IT to Aerospace and R&D.
I develop back-end applications in C++, Julia and Python and avid Generative AI optimist.
My main research interests are developing algorithms and systems that can scale to large problems because that's what enables solutions to deliver real-world impact.
Outside of work I enjoy travelling, photography and just applying mathematics (in ways that generative AI struggles) to solve the most challenging impactful problems.
