  • Designed and developed a scalable and maintainable microservice with a webserver and workers for identity verification of new and existing shoppers using a vendor called Persona. Webserver was handling 300 requests/min. This product feature automated verification of shopper's identity and helped to avoid fraudsters entering the system and saved revenue.

  • Integrated new technologies into existing systems, increasing capabilities and improving overall performance. Created a temporal workflow for creating virtual cards for new shoppers . This was originally a cron job that was running for more than 25 hrs. Temporal workflow eliminated the delay in processing virtual cards for new and existing shoppers and avoid loosing revenue.
