Not every engagement starts with a blank page. A lot of useful work is making an existing system behave: finding the real cause of a bug, modernizing a fragile layer, improving performance, or adding a feature without destabilizing the rest of the product.
I work inside the codebase and conventions that already exist. A rewrite is a last resort, not a default.
What this can include
- Bug diagnosis and repair
- Feature development in an existing codebase
- Legacy modernization and refactoring
- Reliability and error-handling improvements
- Performance work
- Ongoing maintenance and deployment support
Example engagements
- Track down a production bug that is hard to reproduce
- Modernize an aging backend or mobile codebase
- Add a feature to an unfamiliar product
- Stabilize a flaky integration or background job
Examples describe the shape of the work, not past client engagements.
