Freelancer profile translated to English.
Back to original languageAbout Jean-François
Frontend lead developer (but not only), I have been able to intervene in numerous contexts with varied requirements (multilingualism, white label, accessibility, web performance, responsive), with strong quality constraints on high-traffic sites (automated tests, CI/CD, SLA). I have worked in France and also in several other countries, mainly in B2B contexts in the energy, finance, and banking sectors.
I like to listen to business needs and deliver features based on DoD that involve as few back-and-forth iterations between QA and development as possible.
In strong partnership with POs, I help the product meet business/functional requirements and challenges.
Aware of AI tools for a year, I use Cursor daily to increase my productivity, deliver functional (personal) apps, and expand my scope of intervention.
On the agenda: BMAD methodology improved my way with automatic writing of QA tests, backend + frontend, MCPs, automated development, improvement of the context window, and search for qualified examples.
The topics on which I can help you as an augmented developer:
- Performance audit, MOA and frontend development workflow,
- High-level advice and validation on web and agentic AI strategy,
- Front-end architecture design and audit for high-traffic sites,
- Development of web apps and POCs as well as accessible interfaces,
- Advice on mobile and responsive UX strategy,
- Animation and design of application interfaces,
- Product Ownership
What I would like to bring to your projects:
- The experience of a senior who has worked with renowned French internet players,
- A global and informed perspective on your digital strategy,
- Better risk management in user-centered web development.
