Back to original languageAbout Hugues
Centralien Engineer with 12 years of experience and a Founding Engineer profile, I support companies in creating high-performing, scalable, and quality technological solutions. I am involved in the entire product lifecycle, from design to development to technical team management.
My Areas of Expertise:
- **Python Backend Expertise**: Design and development of robust architectures (Hexagonal, Clean Architecture). TDD advocate to ensure reliable and maintainable code.
- **Cloud & Serverless Architecture (AWS)**: Specialist in the AWS ecosystem. Design of highly resilient systems.
- **Tech Lead & Team Management**: Technical leadership of squads, recruitment, mentoring, and ensuring overall technical consistency.
- **Agile Governance**: Implementation and optimization of Scrum methodologies to streamline delivery cycles.
Why collaborate with me?
Beyond my Centralien Engineer training, I bring a "Founding Engineer" vision capable of carrying an infrastructure from the initial idea to hyper-growth:
- **Mastery of Large-Scale Serverless**: In my last role, we implemented a 100% Serverless system comprising over 1000 Lambda functions in production.
- Expert in Hyper-growth: Supporting the company from its first year to Series B, with advanced automation allowing for the processing of hundreds of daily reimbursements (over 50% automated).
- Drastic Cost Optimization (FinOps): Despite this technical complexity and support for over 65,000 clients, we maintained a controlled AWS bill under €5,000 per month, demonstrating an optimized and efficient architecture.
Whether it's to stabilize an existing product, automate your processes, or launch a new platform, I combine rigor, founder pragmatism, and human leadership.
