Senior Software Engineer II / Tech Lead
Data engineering tech lead with a background in neuroscience research.
Building healthcare finance systems on Databricks, leading teams, and teaching engineers to use Claude and Codex.
I'm a senior software engineer with 8 years of experience building data platforms, leading engineering teams, and architecting cloud infrastructure. Behavioral neuroscience research at Harvard and Boston Children's Hospital still shapes how I work: define the problem carefully, test assumptions, communicate clearly, and iterate until the system makes sense.
Currently at Aledade, I lead data engineering for Databricks-based healthcare finance systems that support value-based care. My focus is MSSP financial data ingestion — a revenue-critical workflow representing nearly $1 billion annually — along with SOX-aligned pipeline security, hiring, and technical mentorship. 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.
