A global freelance marketplace requires seamless, secure, and flexible payment infrastructure to support millions of users across different regions. Skillian was engaged to enhance this infrastructure by integrating multiple payment gateways to improve reliability, compliance, and user experience.

💡 The Challenge:

With freelancers and clients operating in various countries, the platform needed to offer multiple payout and payment options. Each gateway (e.g., Payoneer, Braintree, Adyen, Bank of America) had unique APIs, security requirements, and error-handling protocols — making integration complex and highly sensitive.

🛠 Our Contribution:

As part of the back-end engineering team, Skillian led the successful integration of major global payment providers:

🔐 Secure API Integrations – Established encrypted communication channels for Payoneer, Braintree, Adyen, and Bank of America (BoFA)

🔄 Reliable Data Flow – Ensured accurate and consistent data exchange between the platform and external gateways

🛡 Compliance & Security – Implemented strong encryption, tokenization, and compliance measures to protect sensitive payment data

⚠️ Error Handling – Developed intelligent logic to detect, log, and recover from failures during payment processing

🧪 Robust Testing – Validated integrations with sandbox and live environments to ensure smooth, real-world operation

✅ Results:

The platform now supports diverse payment workflows with improved reliability and user trust — reducing friction for both freelancers and clients while meeting strict compliance and security standards.
