01 Introduction

I follow problems all the way down the stack.

I started on the frontend and kept following the problems downward — into data models, APIs, access control, and the servers that keep everything running. Today my work spans backend engineering, database design, API development, deployment, and production maintenance.

At Corunit Media Corp I work on a production Electronic Medical Record platform: patient intake, clinical documentation, scheduling, billing, and the administrative tooling around them. I’ve also led a B2B customer portal end to end, and I bring a grounding in machine learning and NLP from a data science internship.

More about how I work

  • Understand the workflow first

    Software for clinics and businesses only works when it matches how people actually work. I start with the workflow, then shape the data model around it.

  • Own it through production

    Shipping is the midpoint. I stay with features through deployment, debugging, and client-reported issues until they hold up in real use.

  • Treat data with care

    Role-based access, audit trails, and careful handling of sensitive records are defaults in how I design — not something bolted on later.
