Back to original languageAbout Emmanuel
Hello,
I am currently available full-time or part-time, on-site or remote.
🔌 Feel free to contact me
A fullstack developer specializing in web technologies, I have worked for over 5 years in startups, as well as in a telecommunications multinational, a European association, and (voluntarily) on Wikipedia.
During my most extensive experience, in the field of autonomous vehicles, I led a team of 5 people to develop a software platform for managing a fleet of autonomous vehicles in the logistics and private site security sectors. I collaborated with prestigious clients such as Nokia, EDF, and DB Schenker, in France and Finland.
I worked for over 2 years with the support of a mentor with 20 years of experience in Silicon Valley, from whom I inherited several development practices:
- preferring open-source to avoid vendor lock-in, in the client's long-term interest;
- fostering a culture of benevolent code review to upskill teams;
- unconditional use of tests and deployment pipelines in the development cycle.
As a fullstack developer, I can carry out the following missions for you:
Web and Hybrid Application Development
- Back-end: Python (Django, FastAPI), TypeScript (Node.js), SQL (Postgre, MySQL), AWS (EC2, RDS, Aurora, S3, ECS, ECR, SNS, SES, Lambda)
- Front-end: TypeScript/JavaScript, Angular, React, HTML/CSS
- Code review, continuous improvement of the "software development process", agile methodology (scrum/kanban), TDD
- Management: lead development team
DevOps, CI/CD
- Docker & Docker-compose
- Continuous Integration (Bitbucket Pipelines, Gitlab CI)
- Deployment (Terraform, Ansible, Docker)
