Rescuing a Failing Fintech Payment Gateway for a Strategic UK Client
Client Overview: A mid-market payment processor in the UK faced a critical failure. Their outsourced team had delivered a gateway that crashed under 50% of the projected load, threatening their license and primary client contracts. The code was undocumented and riddled with concurrency issues.
Critical Challenges
- Zero existing technical documentation
- Critical security vulnerabilities in the auth layer
- Database deadlocks occurring every 4 hours
- A 30-day deadline before contract termination
The Solution
We deployed an AI-Enabled Fintech Rescue POD within 48 hours. Our team performed a deep code audit using agentic analysis to map data flows. We implemented a redis-based caching layer to offload the database and refactored the transaction logic to handle concurrent requests safely.
Turnaround Outcomes
- System uptime increased from 82% to 99.99%
- Transaction throughput improved by 450%
- Technical debt reduced by 60% in 4 weeks
