Payments / banking / fintech feature developmentAdam Zaghouani
I've built a real payment and banking software: cross-border settlement (PAPSS), a SWIFT→ Mastercard bridge, dividend engines where rounding can't be wrong. If you work in fintech and need someone who already speaks the domain, that's me.
You get:
Domain-aware feature work: transaction flows, maker-checker approvals, audit trails, reporting
Integration with payment rails and standards (ISO 20022 / SWIFT MT, card-network APIs)
Secure messaging (Kafka, JMS/AMQP) and bank-grade auth (mTLS, OAuth, MFA, LDAP/AD)
Accuracy where it matters, calculation logic with fee/tax/FX/rounding handled properly
Ideal for: fintechs, banks, or payment startups who'd rather hire domain experience than train it.
