  • Led the design and development of clever sync micro service which integrates 3rd party source clever into our application. Goal of this microservice was to setup ingestion pipeline and auto sync of new customers and their district data without manual onboarding. Tech stack used - go, microservices, postgres, ecs, sqs, sns, clever
  • Led the design and development of single sign-on authentication micro service for the users of clever(3rd party) account management platform into our native application through oauth2.0, oidc and AWS cognito. This allows users of clever platform to seamlessly login/logout in our application using sso without doing any explicit account registration and maintaining separate credentials in our application cognito user pools. Tech used - go, postgres, cognito, oauth2.0, clever oauth api
  • Worked on building analytics dashboard for our wingspan platform using snowflake as data warehouse. Goal of this feature was to migrate to snowflake due to high latency, increasing users and increasing compute cost of aurora postgres db. As part of this, we did re-modelling of all the queries in our postgres and built new models for snowflake. This significantly reduced load time by 90% using new models which are flatten model of our existing query with extensive joins to avoid recompute on fly with every api call to render dashboard. We had a glue job which used to run periodically and sync postgres data in flatten model and provide us eventually consistent data . Tech used: Go, Snowflake. postgres
  • Led the integration of sentry application monitoring system in our application. This helped us segregate the critical prod issues and alert our team through jira ticket and sentry bot integrated in slack. Integration with jira platform helped with automation of ticket creation for issue to better track in system for other stakeholders. Also integrated mail notification on cloud watch alarms for RDS max utilization which helped in monitoring of our DB load and take informed decisions on managing resources. Tech used - sentry, go, cloudwatch, sns
