About Régis

Software engineer for over 10 years for SaaS software publishers in the Lyon region, I am passionate about the business and business challenges of the companies I support, as well as software quality in all its forms.

🛠️ .NET & Angular technical expert, I pay special attention to application architectures and various testing strategies. A follower of Domain Driven Design, I design applications from scratch with a "Domain first" approach, notably implementing Clean Architecture and an acceptance testing stack, thus promoting the use of ATDD within the team. Encouraging a zero-bug policy, each iteration is an opportunity to improve the quality and resilience of our systems while minimizing technical and/or accidental complexity.

⚡ Constantly seeking efficiency, I strive to find organizational solutions to improve the velocity and effectiveness of one or more squads. This is why I am a strong advocate of Continuous Deployment, which drastically reduces the lead time between the conception and the deployment of the chosen solution.

🏢 Driven by user impact, I actively collaborate with product management to collectively find the most suitable solutions for our clients' needs. I adopt a "Customer centric" approach in my work, primarily addressing their challenges rather than focusing on the technical aspects or the means employed.

🙏 Motivated by teamwork and collective effort, I am committed to the teams and individuals I support in co-creating a healthy and benevolent environment where everyone can share their knowledge, experience, and recommendations to elevate the team's overall expertise.
