About Sean Neilan
I\'m a technical leader and full-stack engineer with over a decade of experience building software from the ground up. I am currently V.P. of Engineering at Grantpuma, where I have been the founding engineer on the team and led the technical direction—including designing cost-efficient ML pipelines and managing AI-augmented development workflows. I\'ve built KYC-compliant banking systems in fintech, scaled search infrastructure, and founded a software consultancy that grew to $300k in annual revenue. I am drawn to hard problems, clean architecture, and shipping software that solves real problems for the people using it.
