Tech Lead @ Crédit Agricole

Joël Mieze

Tech Lead specialized in application architecture, software industrialization and security, currently at Crédit Agricole. I drive full ownership of the software lifecycle: technical scoping, design, implementation, testing, CI/CD automation, deployment, monitoring and continuous improvement. I am accountable for technical quality — scalability, observability, technical debt and coding standards — as well as GDPR and InfoSec compliance on mission-critical platforms. I act as a senior interface between business, engineering and control functions, providing expert-level technical leadership without direct line management.
