Add Features to Legacy Code
You need new features but the codebase is scary. Nobody wants to touch it. One wrong change and everything breaks.
Sound Familiar?
Developers refuse to work on the codebase
Simple changes break unrelated features
No tests, no documentation
Original developers long gone
Business needs new features urgently
How I Can Help
Careful analysis of existing code
Add tests around areas to change
Make changes safely with minimal impact
Document as we go
Gradually improve code quality
Legacy code doesn't have to be scary. It's just code that works but isn't well understood. The trick is making changes safely.
I add characterization tests first - tests that capture what the code currently does, right or wrong. Then changes can be made with confidence.
New features get added with minimal touching of existing code. Over time, the codebase improves. But the priority is always: ship the feature, don't break existing stuff.
You get your features and gradually improved code quality. No big bang rewrites, no risky changes.

What Clients Say
"Stu gets AI development. He's fast, clever about what to automate, and ships real working tools. Most developers talk about AI - Stu actually builds with it."

"Stu and I built an AI-powered documentation review tool together - it handled PR reviews, added frontmatter, found and linked related docs automatically. We went from idea to working product incredibly quickly. He's fast, he gets AI, and he's genuinely fun to collaborate with."

"We needed a booking platform with a full API and mobile app. Agencies quoted six figures. Stu built the prototype, we got users on it, validated the concept. Now we're doing a full rebuild and it's still a fraction of agency prices. He actually ships."
