About Nicolas

COBOL Developer Analyst with 6 years of experience in a banking environment (Crédit Mutuel – EID), specializing in critical mainframe systems.

I am involved in the entire project lifecycle:
– functional and technical analysis
– COBOL development (batch & online)
– DB2, JCL
– unit testing and delivery

Accustomed to demanding and regulated contexts, I work autonomously while ensuring fluid communication with business and technical teams.

My background also includes DevOps / Cloud experience (AWS, Docker, Terraform), which allows me to easily integrate into legacy modernization projects or interfacing with recent systems.

I am primarily looking for long-term assignments on structuring and sustainable projects.
