NovixPay Payment Platform
NovixPay required a modern, PCI-compliant payment platform built for speed, reliability, and regulatory compliance across multiple payment methods.
The Problem
The founding team had been burned by a previous dev partner who delivered an unstable, insecure codebase with zero test coverage and no compliance documentation.
Our Solution
We rebuilt the entire platform from the ground up with a security-first architecture, PCI DSS Level 1 compliance, and a double-entry accounting system.
Our Role
Backend engineering, security architecture, payment integration, frontend development, compliance documentation.
Tech Stack
Architecture
Monolithic core with an isolated payment processing microservice. Double-entry accounting system with immutable transaction logs. Automated PCI audit trail.
Our Approach
Security-first architecture review before writing a single line of code
Automated compliance testing integrated into the CI/CD pipeline
Staged rollout: internal testing → beta merchants → full production launch
24/7 monitoring with automated incident response for the first 30 days post-launch
Key Challenges
Meeting PCI DSS Level 1 compliance within an aggressive startup timeline
Building idempotent payment processing to handle network failures gracefully
Implementing real-time fraud detection without adding latency to transactions
Supporting 6 different payment methods with a unified API interface

Security incidents
After our first dev partner disaster, we were skeptical. Commit4 restored our faith. They delivered a bulletproof payment platform in 14 weeks flat.
