About Fabrice

Software engineer with proven experience in various contexts — business applications, information systems, distributed architectures — I intervene where projects need a profile that is both technically grounded and capable of taking a high-level view.

Depending on the needs, I can take on several complementary roles:
🔧 Solve complex technical problems — code audit, performance analysis, identification of bottlenecks and implementation of concrete solutions
🏗️ Design robust software architectures — definition of technical directions, scoping of solutions, microservices design, guidance on technological choices in line with business and infrastructure constraints
👥 Coordinate and lead development teams — technical management of teams, interface between business, IT, and infrastructure teams, facilitation of practices
🛠️ Contribute directly to development as an experienced and versatile developer
📍 Available in Lyon and remotely — feel free to contact me to discuss your needs.

Curious and continuously learning, a stint in Data Science opened me up to the world of AI and naturally led me to what is transforming software development today: AI agents.
Where a classic LLM is content to answer, an agent acts — it chains tools, calls APIs, executes code, delegates to sub-agents, and self-corrects.
I am actively exploring this approach, particularly through Claude Code, as well as context engineering: the art of precisely structuring what is provided to the model — system prompts, memory, context orchestration — to maximize its reliability and relevance in production.
This dual expertise allows me to approach projects with both a pragmatic and forward-looking vision, identifying concretely how these approaches can increase the productivity of a development team.

    October 2023 - October 2025 (2 years)

    Within the digital transformation program for Nuclear and Thermal operations (DPNT), I acted as Tech Lead for the redesign of a critical radioprotection application — access control in controlled areas and real-time radiation measurement for personnel in nuclear power plants.

    In a context of high safety and compliance stakes, the mission covered a broad spectrum from design to delivery:
    - Definition and formalization of the target software architecture, in line with business, security, and infrastructure constraints
    - Team building — recruitment and integration of 3 development teams, structuring onboarding for rapid skill development
    - Daily technical management — team facilitation, technical arbitration, maintaining consistency and quality across all developments
    - Cross-functional interface — participation in technical and business committees, support for Product Owners in prioritizing and scoping functional requirements
    - Direct contribution to development
