• Participated in the entire release life-cycle of the Hinge reboot. From the initial product inception to the first release and beyond.
• Designed and implemented globally load balanced Kubernetes clusters. These clusters service all the API traffic for the app.
• Created a fully automated deployment pipeline (Commit->Test->CI->Deployment). Developers can tag branches which will create docker containers and deployment them safely in AWS. Built in Go using Consul at first, then.
• Created Microservice Architecture: Application config and service discovery is managed through Consul, HTTP traffic is routed through Fabio and gRPC traffic is handled via Consul DNS. Service communicate via protocol.
• Created performance-critical portions of the architecture with Go based mircoservices. Reduced TCO further by replacing Python services with Go.
• Created the entire backend in one month for the Hinge Matchmaker stand-alone product.
