Your payment system is in production and a bug is blocking transactions. Your banking partner is waiting for a response. Your technical team doesn't know ISO 8583. This is exactly where I come in.

An engineer specializing in payment integration and Oracle PL/SQL, I have 4 years of experience with critical payment systems in a real banking environment. At S2M — a major player in payment processing in Africa — I managed the complete integration of ATM, POS, and Switch solutions for several African and international banks: ISO 8583 Visa and Mastercard interfaces, terminal certification, payment platform migration, PCI DSS compliance, and level 2/3 incident management.

Before that, at Logigroup, I developed and optimized Oracle PL/SQL components for financial data management applications: stored procedures, ETL pipelines, complex queries on large transactional volumes.

What sets me apart on Malt: I master both the database layer (Oracle PL/SQL) and the payment protocol layer (ISO 8583, EMV, payment processing). Most consultants cover one or the other — not both. My experience in Africa and the MENA region is also a real asset if you operate in these markets.

I work in French and English, deliver documented work, and treat go-live deadlines as a non-negotiable constraint.

If you have a payment integration, Oracle development, or payment compliance project — send me your brief, I'll respond within 24 hours.
