J. Scott Chapman

Product Engineer

You have the idea. I build the product, ship it, and prove it works. One person. The whole loop.

I work with founders, health-tech companies, and teams who need a product built from scratch.

The Short Version

I build full-stack products from the ground up. I take a vague idea, figure out what it actually needs to be, architect it, build it, ship it, and measure whether it worked. Healthcare platforms, AI-powered products, data pipelines from wearable devices to clinician dashboards. The kind of work where "it's someone else's department" isn't a viable sentence.

Ten years ago I was running fire protection crews at a nuclear plant in South Carolina. Then I learned to code, quit smoking a pack and a half a day, and started building software that helps people. The through-line is straightforward: I like solving problems that matter, and I have very little patience for ones that don't.

Based in Montana. Working remotely since before it was mandatory.

What I Actually Do

Most teams solve this by hiring an agency (slow, expensive, nobody owns the outcome) or a freelancer (writes code to your spec, never questions it). I do neither. I own the problem from discovery to metrics.

Product Engineering

You describe what you want. I figure out what you need. Then I build it, ship it, and hand you the numbers that prove it works. The whole loop, one person, no telephone game.

AI & Machine Learning

Four AWS AI/ML certs and hands-on experience building agentic systems. I deploy models where they solve actual problems, not where they make good slide decks.

Healthcare Tech

HIPAA-compliant platforms, medical device data pipelines, clinician-facing dashboards. I've built the full path from a BLE sensor on someone's body to a chart on a doctor's screen.

Systems That Run Themselves

Automated onboarding, data-driven engagement campaigns, multi-provider failover. I build systems designed to keep working while you sleep.

Work That Worked

TechFix SMS: Doubling Engagement With Personalized Texts

A client came to me and said, roughly: "What if we texted students reminders to study?" That was the entire brief.

I dug in and discovered the real problem. Students had knowledge gaps nobody was tracking. Outreach was generic and sporadic. Nothing scaled. So I built an automated platform that categorized students by their weakest subject, sent personalized daily training links at 7 AM, tracked delivery across dual SMS providers, and gave admins a dashboard to see everything in real time.

2x student engagement
98%+ SMS delivery rate
10 hrs/wk admin time saved

Morphose: 3D Physical Therapy, HIPAA and All

Physical therapists were handing patients printed sheets with stick-figure exercises and hoping for the best. I built Morphose: a HIPAA-compliant platform with a library of 850+ interactive 3D exercise animations, real-time progress tracking, secure messaging, and therapist dashboards for prescription management. The whole thing replaced a paper handout with a system that actually shows you how to move your body correctly.

Continuous Glucose Monitor: Device to Dashboard

At Estenda Solutions, I built the visualization layer for a proprietary continuous glucose monitor. The device talked BLE to a phone, the phone pushed data to the cloud, and I built what the doctor saw on the other end: longitudinal glucose trends, time-series readings, and the clinical context to make treatment decisions. The full pipeline from a sensor on your arm to a chart on your physician's screen.

Get In Touch

I take on a small number of projects at a time, typically 2-4 month product builds from discovery through launch. If you have a problem worth solving and you want someone who'll own the outcome, not just the code, let's talk.
