Who am I?
Software development engineer, I put my technical expertise and rigor to work for your digital projects. My background is marked by a dual culture: the precision of software engineering acquired within demanding groups like Thales and solid field experience as an international field technician. This duality allows me to understand both complex technical challenges and the real needs of end-users.
My areas of intervention
Whether you need to launch a project from A to Z or strengthen a team on a complex business architecture, I will support you with a modern and high-performance stack:
- Web & Mobile:Development of robust and fluid interfaces with Angular and Flutter.
- Back-end & Performance:Design of high-performance APIs and systems, particularly in Rust and NodeJS.
- Design & UX:Sensitive to ergonomics, I design your mockups and develop interfaces to ensure an optimal user experience.
Why work with me?
- Industrial Rigor:With experience in simulation and air traffic control at Thales, I apply best development practices (SOLID, Design Patterns) to ensure sustainable and maintainable code.
- DevOps Culture:I automate your processes via CI/CD pipelines (Gitlab, Github) and ensure hosting on Google Cloud for seamless deployments.
- Agility & Commitment:Experienced in Agile methodologies (Scrum), I quickly integrate into your teams.
Modalities
Based in Poussan (Occitanie), I am available for 100% remote work missions or hybrid formats in the region. Let's discuss your needs to transform your ideas into high-performance software solutions!
