Description

Based in Brittany and mobile in France, I have been supporting companies of all sizes for 18 years — startups, scale-ups, and large corporations — on their fullstack Java / Angular projects, as:

Transition CTO / Fractional CTO
Tech Lead
Software Architect
Senior Fullstack Developer
Mentor / Trainer / Code Auditor

Main stack:

Back-end: Java 17/21, Spring Boot, WebFlux, Quarkus, microservices, PostgreSQL, MongoDB
Front-end: Angular (2 → 21, Signals), RxJS, NgRx, Nx, micro-frontends, TypeScript, Tailwind
Quality & Testing: JUnit 5, Testcontainers, Cucumber, Jest, Vitest, Cypress, SonarQube
DevOps & Cloud: Docker, GitLab CI, Azure Pipelines, AWS, GCP, Terraform

I also work on legacy code — whether it's old codebases or recent but poorly structured code — to audit, stabilize, and modernize it without blocking teams.

Some notable projects:

CITEO — Frontend lead, modernization to the latest Angular standards
GRTgaz — Tech Lead of a product team, Java / Spring Boot microservices on 5 products; Front Chapter Lead of a SAFe program (~80 developers, 10 applications)
Agicap — Frontend lead for a product line of ~40 people, micro-frontend strategy
Angel & Endrotek — Fractional CTO: Java/Angular platforms designed and delivered from scratch to production
BNP Paribas CIB, Société Générale CIB — critical financial market applications

What I bring you:

Owning a product end-to-end, from stack choice to production deployment
Architectural decisions aligned with your business challenges
A critical and constructive view of your code, technical choices, and processes
Skill development for your teams (pair programming, reviews, workshops)

Whether you are looking for an outsourced CTO, a Tech Lead, an architect, or a fullstack Java / Angular developer, I can assist you from scoping to delivery.
