Why Doesn't My Code Work?
For builders who got stuck mid-build

You built something amazing.
Then it stopped working.

You used AI to build fast. Now nothing deploys, errors make no sense, and you're mass-pasting into ChatGPT at 2am. I've shipped 30+ products across multiple tech stacks. Let's get yours across the finish line.

30+ Products Shipped
10+ Years Experience

Sound familiar?

$ npm run build
ERROR Module not found

It worked on my machine

Your app runs locally but the moment you deploy, everything falls apart. Vercel shows red. Netlify times out. You have no idea what's different.

$ git log --oneline
47 commits "fix"
23 commits "try again"

Commit message: "please work"

You've been pasting errors back into the AI for hours. Each "fix" creates two new problems. The codebase has grown beyond what you can reason about.

client said:
  "can we launch friday?"
you said:
  "..."

The deadline already passed

You promised something that seemed possible with AI tools. Now you're stuck, the client is waiting, and you need someone who can actually ship it.

From stuck to shipped

Three steps. No judgment. Just results.

01

Show me the mess

Book a session. Share your repo, your errors, your deploy logs. I've seen it all: broken builds, spaghetti state management, auth loops, database migrations gone wrong. Nothing shocks me.

02

I diagnose the real problem

Most "bugs" are architecture problems. I'll trace your code from entry point to failure, identify what's actually broken (not what the error message says), and map out exactly what needs to change.

03

We ship it together

I don't just hand you a list of problems. We fix it live, pair-programming style. You watch, you learn, and when we're done, your app works and you understand why.

Real problems. Real fixes.

A few of the 30+ products I've taken from broken to shipped.

Education Platform

Doubled student engagement for a training company

A client had students falling off between assessments. I built an automated SMS engagement system that tracked progress and sent targeted messages. Result: 2x engagement, 98%+ delivery rate, thousands of messages across multiple cohorts.

Healthcare Platform

Built a HIPAA-compliant physical therapy platform from scratch

Sole developer on a platform with 850+ 3D exercise visualizations, real-time progress tracking, patient messaging, and therapist dashboards. Replaced static 2D exercise instructions with interactive motion capture.

React / Node.js / Three.js / PostgreSQL / AWS
Medical Devices

Connected wearable sensors to clinician dashboards

Built the complete data pipeline for a continuous glucose monitor: BLE data from wearable sensor to cloud ingestion to physician-facing clinical visualization. Device-to-doctor, end to end.

I'm J Scott Chapman.

Product manager and technical consultant with over 10 years of experience. I've been a JavaScript instructor, a conference speaker, and the sole developer on healthcare platforms where code failures have real consequences.

I'm not here to judge your vibe-coded project. I've used Claude Code to build production apps myself. I know exactly where AI-assisted development shines and where it falls apart. That's why I built this service.

I'm a product partner, not just a developer. I don't just fix the bug. I help you understand why it broke, how to prevent it next time, and how to think about your project architecturally so the AI tools work with you instead of against you.

Frequently asked questions

What is vibe coding?

Vibe coding is using AI tools like ChatGPT, Claude, or GitHub Copilot to generate code from natural language prompts. It lets non-developers and developers alike build apps fast, but projects often break when it's time to deploy, debug, or scale.

How much does a debugging session cost?

Sessions start at $125 per hour. A Diagnostic Session typically takes 1 hour. A Ship It Session (where we fix it together) usually runs 2-4 hours. Ongoing support starts at $2,000 per month.

What tech stacks do you support?

I've shipped 30+ products across multiple tech stacks including JavaScript, Node.js, React, Next.js, PostgreSQL, MongoDB, AWS, Three.js, BLE, and more. If it runs on the web, I can debug it.

Do I need to know how to code?

No. Many clients are non-developers who used AI to build something and got stuck. Sessions are pair-programming style — you watch, ask questions, and learn as we fix it together.

How do I book a session?

Visit my booking page and pick a time that works for you. No pitch deck or intake form required — just tell me what's broken.
