Bio

Co-Founder, Parameter. At Codegen, I built asynchronous coding agents that improved the workflow of developers, and even got non-developers writing production software. At AMD, I built infrastructure for MI300 GPU firmware testing. I competed internationally in piano, winning multiple competitions and performing with orchestras like the Qatar Philharmonic Orchestra.
