- I’ve worked on designing a solution to migrate data consumption from Database to Kafka. This required a thorough analysis of product functionality spread across microservices, discussing approaches & trade-offs. Led team by creating user stories, developing, code-reviewing & deploying to deliver the functionality.
- I’ve worked on splitting a monolith into two micro-services; during which I’ve designed & implemented ~20 REST APIs w.r.t API First standards.
- Led a project of migrating alerts/dashboards/reports of ~20 microservices from the legacy system to Splunk.
- I've planned and migrated four applications running on legacy infrastructure to centralized Kubernetes clusters which are distributed in 20+AWS accounts.
- I’ve worked on designing strategies to set up Datadog(external observability SaaS) across services inside the company. This required me to work with Deployment infrastructure teams, preparing internal spring boot templates which carry installation/setup code, and automated datadog agent installation on standalone AWS EC2 machines with event triggers by using AWS Systems Manager.
