Software Engineer

Salesforce
Nov, 2024 - Present1 yr 5 months

SDE

JUSPAY
Apr, 2022 - Aug, 20242 yr 4 months
    Designed in-memory cache service, engineered stateless microservice, implemented idempotency and API locking mechanisms, developed transaction audit trail, enhanced transaction routing, and revised API error handling.

Associate Software Engineer

GlobalLogic
Mar, 2021 - Apr, 20221 yr 1 month
    Developed asset management system leveraging CQRS design pattern, implemented Debezium Kafka Connector for real-time synchronization, created microservices for asset management and failure prevention, and improved inter-service communication using gRPC.

Achievements

  • Designed an in-memory cache service to alleviate database load, resulting in a 10% reduction in API latencies
  • Engineered a stateless microservice to disentangle payment gateway logic from the core flow, standardize flows via gateway DSL resulting in a 50% reduction in integration time
  • Implemented idempotency and API locking mechanisms within APIs to maintain transactional integrity
  • Developed a transaction audit trail which involved transitioning from unstructured to structured logs, resulting in a 20% reduction in compute and storage costs
  • Developed cross border and hybrid pricing functionalities in VISA Lending Services
  • Enhanced transaction routing with secondary gateway retries, coupled with refined gateway scoring logic
  • Led the development of an asset management system at Hitachi Energies
