PHP Developer for Existing Projects
You have an existing PHP codebase — Symfony or custom — and need someone who can pick it up quickly, fix bugs, extend features and keep it stable without a rewrite. I specialize in working with existing systems.
What I Can Help With
Work on an existing PHP project — extensions, fixes and maintenance.
Typical Problems
Relevant Experience
Regularly pick up existing PHP codebases — most recently helped extend a Symfony application processing traffic analytics data. Comfortable reading unfamiliar code, reproducing bugs, and making changes without breaking existing behavior.
What Is Included
How It Works
I read your code and tests, reproduce the issue, and fix it with minimal risk. Hourly rate €60. I can work short sessions or embedded in your team.
From €60/h
Follow-up implementation rate once the problem is diagnosed. Bug fixes start with a quick diagnosis — then a fixed quote, not an open-ended meter.
Frequently Asked Questions
How quickly can you start on an existing codebase?
Usually within a day. I start by reproducing the problem and reading the relevant code/tests before touching anything.
