At American Express Global Business Travel (Egencia), I build payment routing, transaction eligibility, and offer evaluation systems. I designed a hexagonal architecture refactor that removed 750 lines of duplicate code, and a strategy-based offer evaluation service that processes 250,000 requests a day.
I also built pr-ready-check using Claude Code to run engineering checks locally before a PR; it was deployed org-wide and saves 45–60 minutes per developer CI cycle. Previously, at Amdocs Development Center, I built Java and C# backend services, resolved production issues, and reduced API response times by 25% through database optimization.
