About Marc

IBM i (AS400) Developer Analyst with over 30 years of experience in banking, insurance, energy, and services.
Specializing in RPG IV / ILE, CLP, SQL, and ADELIA development, I am involved in the entire application lifecycle: analysis, specifications, development, testing, deployment, support, and training.
Rigorous and autonomous, I am recognized for my ability to ensure application reliability and scalability.
With strong interpersonal skills, I quickly integrate into teams and adapt to the organization and functioning of the company.
I have been working as an independent consultant since June 2022.
My goal is to become a Swiss resident and offer my expertise to Swiss companies.
