SenturoPay

Challenge

The platform required secure transaction orchestration across fiat and crypto rails while integrating third-party providers. It also needed compliance-oriented traceability and operational reliability under financial transaction constraints. The system had to handle upstream API failures without exposing sensitive processing details.

Solution

We implemented provider integration layers for Paybis (fiat onramp/offramp) and Kraken (crypto swaps), with strict validation and failure isolation at service boundaries. We structured backend capabilities across Node.js, .NET, and Java to separate transaction orchestration, integration adapters, and operational controls. On mobile, we used Flutter to provide consistent payment and status flows. We applied idempotency, retry, and auditable event patterns to keep transaction handling reliable and reviewable.

Results

• Integrated 2 external financial providers into one payment workflow.
• Running active delivery since Jan 2025 with ongoing production enhancements.
• Established secure transaction handling across a 4-technology backend/mobile stack.
