About Jo

I launch your projects with an appropriate and sustainable stack, as well as best practices to allow your project to grow serenely (CI/CD, deployments, tests, readable and understandable code).

Founder of a tech startup and lead dev for over three years, I have participated in the design and implementation of several business projects. And I understand very well the need to iterate quickly as well as to have robust code ready to meet the challenges of a new project.

On the other hand, very curious and a lover of new technologies, I try to keep up to date and use them in various projects (personal or professional).

Among the skills that my experiences have brought me:
- Lead Dev: very good communication and team management, implementation of best practices and guarantor of the quality of deliverables (product and tech)
- Tech: use of various development technologies in tandem
- Business: great attention to business and operational detail

Among my tech skills (fullstack and others):
- Expertise in JavaScript (front React/NextJS & Nodejs)
- GraphQL and TypeScript
- Django / Django Rest / Python
- Infra-CI/CD: Terraform / GitHub Actions / AWS / Cloudflare

    ENTERTAINMENT AND LEISURE
    July 2018 - August 2022 (4 years and 2 months)
    As lead developer at Weezevent, I was able to lead and manage a team dedicated to one of the company's products.

    This position allowed me to learn a lot about the human and managerial side in business, while keeping a very present technical aspect. Combined with my business experience, it proved particularly useful in bridging the gap between pure technology and the company's business.

    This position also allowed me to learn how to transmit knowledge to other developers, while taking into account everyone's level and the desired progression, whether personal or at the company level.
