About WislaCode Solutions

WislaCode Solutions is a fintech integration engineering firm registered in Warsaw and contracted under EU jurisdiction. We design and deliver client, partner and provider integrations for banks and B2B fintech platforms - payments, lending, KYC and AML, open banking, BaaS - without replacing the buyer's core systems.

Engagements run as accountable squads with a named technical lead and a documented handover. We work inside the buyer's repository, CI and identity provider, and the source code, mapping logic, tests and runbooks stay with the buyer's team.

Proven in production: a banking super app with 1.5M+ installs where lending grew 150x, a legacy-to-digital migration covering 1.5M+ users without disruption, a mobile bank for a 700K+ customer institution released in six months, payment platforms processing GBP 10M+ in daily transactions, and an Android payment SDK taken to production in one month.

The founders have worked in banking and payments software for over 20 years. WislaCode Solutions was registered in Warsaw in 2023.
