Back to original languageAbout Najib
Looking for a developer who can take a project from start to finish?
Do you need someone who knows how to architect, develop, and move a project forward without needing to be prompted every two hours.
Because, deep down, nobody wants to spend their time supervising a contractor. We want someone reliable, autonomous, and transparent.
I know this because I've hired developers myself in the past.
Why work with me?
For over 7 years, I've been supporting startups and scale-ups likeQonto, Getaround, Cheerz**, and **Schoolmaker.
I bring four things to every mission:
- **Autonomy**: I can take a subject from start to finish.
- **Rigor**: maintainable code and well-thought-out decisions.
- **Communication**: you always know the project's status.
- **Product Vision**: I look for the most relevant solution, not just one that works.
At the end of the day, I'll give you an update on what has been done so you have clear visibility on progress.
Some achievements
- Development of acomplete CMS at Qontofor the Marketing team to manage their content more effectively.
- Design of **Cheerz's new central back-office**, connected to several internal applications, to provide a more modern, faster, and simpler tool to use.
- Performance optimization of theSchoolMakerplatform, used by over 200,000 users.
- Support forSolocalon the evolution of a legacy Ruby application and its integration with a new API.
