Client Regional fintech (Honduras / El Salvador)
Duration 6 months
Year 2023

01 The challenge

The company needed to replace its legacy payment system that neither supported multiple currencies nor met PCI-DSS standards, which was blocking expansion into new Central American markets.

02 The solution

We designed a microservices architecture on AWS with end-to-end encryption, direct Stripe integration for card processing, and a React administrative dashboard so operators could monitor transactions in real time.

03 Results

Processing 50,000+ transactions/month since launch.

  • 50,000+ transactions processed per month since Q1
  • PCI-DSS Level 1 compliance certified by external auditor
  • Transaction response time < 300ms (p95)
  • 70% reduction in fraud through real-time detection system
  • Successful expansion to 3 new markets: Honduras, El Salvador, and Guatemala
