Case studies

Where this has shipped before.

Challenge: Stockholm's transit authority SL needed a new portable conductor device and platform validator for ~800,000 daily travelers.
What we did: Built the Android POS and ticketing app for the Famoco device, tuned its firmware, and integrated it with Ingenico's PCI-certified payment app. The device validates EMV, optical and Aztec-code tickets.
Result: A connected ticketing device that met Swedish work-environment requirements, later rolled out to WÅAB's archipelago ferries.

Challenge: After an acquisition, migrate legacy components to the BigCommerce stack without losing features, and add capacity for an ambitious roadmap that included third-party payments.
What we did: Three teams working as an extension of BigCommerce: legacy modernization, third-party payment integrations, back-office internationalization for Chinese and French markets, and native features that replaced third-party products.
Result: A modernized platform for 60,000+ merchants, delivered continuously over four years.

Challenge: Support a complex acquirer integration while keeping ISO 8583 flows stable, EMV-compliant across Visa, Mastercard and Amex, and ready for PCI DSS while transaction volumes kept growing.
What we did: Improved ISO 8583 and EMV processing for card-present and card-not-present, hardened acquirer connectivity, integrated KYC, and removed bottlenecks across messaging, databases and services, all validated with load testing.
Result: 5× system throughput, a payment platform prepared for PCI DSS certification, and faster acquirer integration.

Challenge: Move merchant billing from daily to monthly reconciliation, which meant switching to a new payment facilitator. Add merchant limits, approvals and transaction caps on top.
What we did: Integrated the new facilitator's APIs into Dynamics 365 Finance & Operations, built configurable limit rules applied on import, approval workflows for limit breaches, and automated merchant file exchange over SFTP.
Result: Full visibility of transaction data and control over merchant accounts, with reconciliation and approvals automated.

Challenge: Digitalize credit-management products for 700+ banks and lenders under pressure from FinTech competitors.
What we did: Re-architected the lending portal on Spring Boot, built a new loan application, and moved the front end to React, adding self-service portals for loan applicants and debt restructuring.
Result: One-year timeline met; two major system updates and two products released: Open Credit 4.0 and a new lending portal.
