Backend engineer at Tata Consultancy Services for VISA, engineering Go payment services with idempotent processing across Kafka pipelines.
IndiaWhat I'm looking for
At Tata Consultancy Services, I engineer Go transaction-processing services for VISA's real-time payment platform. I work on authorization and clearing message flows within a global microservices architecture.
I build Kafka message-processing logic that handles at-least-once delivery, with idempotency and deduplication across message, pipeline, and database layers. This supports exactly-once business outcomes through retries, duplicates, and reversals.
I implement payment-message validation, transformation, and routing between ISO 8583 and internal canonical formats, using a DSL and Go/Java code-generation toolchain. I also apply Go concurrency patterns to support high availability and low-latency processing.
Earlier, at CreditMantri Finserve Pvt Ltd, I contributed to the SBI e-Mudra application and banking services, and built Java/Selenium test automation for mobile and web applications. I'm seeking a backend/Go engineering role in a product-driven organization.
