  • Developed a real-time transaction decisioning system to prevent fraud, generate alerts, detect velocity breaches, and deliver customer notifications — processing 500K+ requests/day with sub-50ms evaluation latency.
  • Optimized transaction processing time by an average of 40% using binary search and efficient XML parsing.
  • Accelerated API performance of a Python-based ML service by implementing Redis caching, cutting response time by 75% and timeout errors by 99%. Handled containerization with Docker and deployed to AWS ECS.
  • Built a two-way communication system between the fraud detection engine and the mobile app, enabling customers to verify and reattempt risky transactions, increasing approval rates by 30%.
  • Implemented parallel Bank-level and Organization-level rule engine API calls using Java Generics, Multithreading and the Template Design Pattern, maintaining low latency and improving system extensibility.
  • Built a fraud mitigation API to block/unblock suspicious MIDs at runtime, avoiding frequent redeployments.
