Back to original languageAbout Arnaud
The important thing is the business need. Technology is at its service.
📍 Available fromAugust 2026— end of current mission at Sopra HR
Since 2015, I have been supporting software publishers and startups on web applications where the complexity comes not from the framework, but from the domain: HR, industry, medical, transport, interaction robotics.
My role: transform these needs into clear, maintainable architectures that can be adopted by the teams who will bring them to life after my departure.
What I work on
- Architecture & Angular development on business applications (Nx monorepos, design systems, domain-specific patterns)
- Audit & refactoring: technical debt, legacy migrations
- Tech lead & mentoring: Angular / RxJS, clean architecture, craftsmanship
- POC / MVP Angular + Node.js / NestJS
- Technical assessment: JS / TS examiner for companies
Front:
- Angular (since AngularJS)
- TypeScript
- RxJS
- Nx
Back:
- Node.js
- NestJS
- Express
- PostgreSQL
- MongoDB
Practices:
- Clean Architecture
- DDD
- SOLID
- tests (Jest)
- CI/CD
- design systems
Why choose me
- Real depth on Angular, not a superficial accumulation of technologies
- Experience in demanding fields (medical, defense, industrial) where errors are costly
- Ability to challenge a need as much as to deliver code
- Proven leadership: I leave your teams more autonomous than before my mission
- Long-term missions (2+ years at Sopra HR, 2+ years at IZHO): I am committed for the long haul
