At Rahgozin Rayaneh's BluBank project, I develop and maintain Instant-Payment, ACHDC, and RTGS services on a microservices-based banking platform. These services process millions of transactions daily.
I designed concurrent transaction workflows that prevent race conditions and preserve data consistency under peak load, contributing to 99.9%+ uptime for critical payment flows. I also implemented transaction-safety mechanisms that brought duplicate-transaction incidents to near zero.
At MyDigipay, I designed a risk-scoring microservice that evaluates user-behavior events and improved fraud-detection accuracy by about 30%. I applied TDD across service modules, increasing code coverage from about 40% to 85%.
Earlier, I improved a high-load data pipeline's throughput by 35% at Mahan Web Gostar Avijeh and built a Java/Angular warehouse platform at Baharan. My work spans backend systems, payment processing, and production observability.
