Freelancer profile translated to English.
Back to original languageAbout Alexis
I design web platforms and applications capable of handling high volumes and maintaining performance in production.
I work on high-stakes projects: SaaS, marketplaces, CRM/ATS, or mobile applications, with an approach focused on performance, scalability, and business impact.
I am the originator of the Jobissim platform, a CRM / ATS dedicated to recruitment:
• +50,000 users
• +30,000 video CVs created
• +8,000 AI-generated CVs
• Management of hundreds of thousands of job offers and content
I also designed the JobiBox, a connected cabin with an embedded screen and proprietary software allowing the creation of: personalized video CVs (green screen, templates, sequences), modular AI CVs, interview simulations, and interactive career paths.
This hybrid product (hardware + software) involves real-time, UX, and performance constraints that I manage daily.
The whole system is based on a robust architecture (Symfony API, Redis, asynchronous workers, Nginx optimization) allowing the elimination of timeouts and ensuring a fluid experience at scale.
I support my clients end-to-end: scoping, architecture, development, optimization, and production deployment (dedicated servers, CI/CD, deployment, mobile stores).
🚀 Results:
• +500,000 offers managed without timeouts
• Scalable architecture (workers, caching, performance)
• Product used at scale (Jobissim & JobiBox)
💻 Stack: Symfony • Angular • React Native • ElectronJS • Node.js • MySQL • Redis
I primarily work with companies facing performance, scaling, or technical structuring challenges.
