Back to original languageAbout Damien
👋 hello! my name is damien and I am a passionate coder 🤓.
For over 15 years, I have been supporting all types of organizations(web agencies, digital agencies, publishers, IT service companies, schools, training centers, startups...) in successfully completing their web projects 🚀.
I specialize in **developing websites and web applications**, working on both the "front" and "back" (PHP) ends. Specifically, I:
- advise on technical choices:
- which frameworks
- which CMS
- which third-party tools (no-code / low-code / AI - LLM)
- design the architecture (especially data structure...)
- develop your application and ensure maintenance and evolution
I also frequently work onexisting projects(even "legacy" ones 🔥):
- code audits
- feature additions
- bug fixes
- version upgrades (PHP, framework, database, ...)
- troubleshooting HTTPS issues
- software architecture recommendations
- refactoring in case of technical debt
- setting up continuous integration and deployment
- writing tests (unit, functional, end-to-end)
- supporting / training existing teams
I can work on a projectautonomously or alongside your team.
Feel free to contact me, I am open to all opportunities! If I am unavailable, I will not hesitate to recommend reliable contacts from my network.
Note regarding daily rates: The concept of daily rates is relatively irrelevant for fixed-price services (which is often the case). Indeed, a senior developer, despite a higher daily rate, is often more efficient at developing a solution than a junior developer. The final cost can therefore be lower than with a junior (not to mention the quality of the service...).
In my case, the daily rate is adjusted according to the nature of the mission and the skills required, and ranges between €250 and €550 per day.
