At Amazon, I designed and built a payment microservice for a new payment partner in Amazon’s Turkey marketplace. It processes approximately 1M transactions per month and delivered $12M in annual cost savings.
I also designed and owned the AWS infrastructure for the integration, and built serverless workflows to automate remittance and accounting-file processing. I architected a migration that centralized payment rules across 40+ payment methods and 20+ services.
At Amazon, I modernized an EU dunning-email system that resulted in $14M in annual savings, and migrated payment services from Dublin to Frankfurt with zero customer-facing downtime. Earlier, at TCS, I developed and maintained a Java-based High Risk Transaction microservice and contributed to its V1-to-V2 migration.
