Critical & legacy systems
COBOL Expertise — maintenance, evolution, modernization
Maintenance and evolution of mission-critical COBOL systems for banks and insurers. Remote team in Paris & Tunis, reinforcement within 2–3 weeks.
COBOL still runs most core operations of large banks and insurers. Solvinya Group secures and evolves these production chains with 8 years of combined experience — including a major Tunisian bank and a long-standing insurer.
What we do
- Corrective and evolutionary maintenance of production COBOL batches
- Packaging, change and lifecycle management (JCL, DB2)
- Integration with modern applications: APIs, queues, ETL
- Step-by-step modernization: COBOL toward services and cloud
- Remote team reinforcement aligned with your production schedule
Frequently asked questions
Do you work time & material and fixed-price on COBOL?
Yes, both. Time & material to reinforce your mainframe teams, fixed-price for a bounded maintenance batch, a migration or a well-scoped evolution.
How do you guarantee continuity of production batch runs?
Critical runs are covered by validation milestones, documented processing and rollback plans — with the team available during your production windows.
Can you take over poorly documented COBOL?
Yes — a classic situation. We reverse-engineer, trace batch flows, map data and take over in controlled blocks.
Why a remote Paris/Tunis team for COBOL?
Controlled cost without quality loss: daytime coordination, overnight batch compiles, supervision shared between your team and ours.
How fast can COBOL reinforcement be available?
Usually within 2–3 weeks: sourcing, security clearance, NDA and ramp-up on your repositories.
