Hussain Shabazz

I’m a software developer with 5+ years of experience building and operating enterprise payment platforms that process billions in transactions. I focus on payment integrations, transaction processing workflows, fraud mitigation, and financial reconciliation systems in high-volume production environments.

At Global Payments, I support a high-volume payment processing platform serving 1,600+ public sector clients. I’ve managed legacy code, supported client integrations, and documented features while processing over $15B in transactions in 2025, helping drive a 6% increase in transaction fees collected year over year.

I’m known for bridging technical and business teams to improve reliability and efficiency. I partner with finance, account management, and engineering to resolve payment issues and deliver scalable solutions, using a system-driven approach through process improvement, automation, and AI-assisted workflows.

I also strengthen security and operations by designing and deploying fraud-mitigation services (including a Cloudflare integration) to detect and block card-tumbling activity. On the operations side, I’ve improved failed-transaction handling, refined ACH verification logic, and optimized log retrieval performance to reduce reconciliation time and accelerate internal troubleshooting.
