Back to original languageAbout Leo
Hello,
My name is Léo,
A frontend web developer for 8 years, including 3 as a tech lead, I've had the opportunity to work on a multitude of projects and meet many developers. These experiences have allowed me to develop technical skills in several web technologies: Angular (recent versions), TypeScript, JavaScript, HTML5/CSS3, as well as solid experience in API development with NestJS/Nodejs. I also have a habit of ensuring the quality of developments using tools such as Jest for unit tests and Playwright for end-to-end tests.
My various missions as a technical lead have allowed me to develop a collaborative ability with all members of a technical team:
- PO (assistance with backlog prioritization and macro-estimation, improvement of User Stories, proposal of techno-functional topics, monitoring of ongoing features and functional testing of completed US)
- Scrum (monitoring of the current sprint and team reorganization as needed, ensuring good productivity, interactions with other teams in the case of a SAFe environment)
- Devs (leading technical analysis and User Story estimation meetings, mentoring developers, implementing quality and CI/CD processes with the DevOps team)
- Design (UX/UI workshop, providing a technical vision)
I have discovered different sectors of activity with large group clients or startups (banking, IT security, construction, energy, accounting) and thus varied team organizations, thereby developing a strong adaptability and team spirit that allow me to quickly integrate into technical teams.
Looking forward to discussing one of your projects!
