Back to original languageAbout Abderrahim
Are you looking for an expert capable of maintaining and evolving your critical systems in a mainframe environment.
Senior IT Consultant, I have been working for over 20 years on highly critical legacy systems (banking, insurance, large accounts). I help my clients ensure the continuity of their operations, make their applications reliable, and support the modernization of their existing systems.
Specializing in COBOL, Pacbase, LINC, and DB2, I am quickly operational on your mainframe environments (MVS, GCOS) and I work in maintenance (RUN), evolution (BUILD), or analysis/design.
What sets me apart:
A rare expertise in still critical legacy technologies
A capacity to intervene quickly in complex environments
An approach focused on reliability, performance, and security
Solid business experience (banking, insurance, industry)
A capacity to transmit knowledge and support your teams
I regularly work on:
Maintenance and evolution of COBOL / Pacbase applications
Analysis and resolution of production incidents
System performance optimization
Legacy system modernization projects
Migration and documentation of existing systems
Support for technical and functional teams
Available for freelance or payroll transfer missions, I quickly integrate into your teams and contribute effectively to the success of your projects.
Do not hesitate to contact me to discuss your needs.
