About

I'm a senior software engineer with 7+ years of experience building full-stack applications, leading engineering teams, and architecting cloud infrastructure. My path from neuroscience research at Harvard to tech gives me a unique perspective on problem-solving.

Currently at Aledade, I lead a team focused on data pipeline security and deployment optimization. Previously at Cognito Health, I built serverless infrastructure spanning the UK and USA, and developed cross-platform mobile apps serving healthcare providers.

Outside of work, I built the booking platform for Rekindle Sauna — a full-stack SaaS with Stripe payments, subscription management, and 15+ Lambda microservices, designed to scale as white-label booking software for any sauna company. I'm also a rock climber who has summited El Capitan.
