Milk Jobs

An instant messaging recruiting platform. I developed part of the React website, part of the React Native apps (iOS and Android), the entire .NET Core back end, and deployed to AWS (CloudFront, Lambda, API Gateway, S3, RDS) utilizing Terraform for configuration management. OpenAPI was used for describing API definition, and various external SaaS were included in the application to provide better functionality, including Algolia, Firebase, Mailgun, Branch.io, Sentry, and SendBird, among others.

I also became a member of OpenAPI Generator technical commitee after actively contributing to the open-source project during the development of Milk Jobs.
