The project is under the NDA. It is a huge and well-known real estate product in the North America.

I have developed a totally serverless application based on microservices. The logic of the endpoint was handled by lambda (including request validation, logic, db connection and providing response). Each Lambda was connected to an API gateway. I have experience in Lambda API deployment and API building using sam template configuration and serverless framework. Including API gateway auto deployment and API gateway specification build. Testing Lambda locally and using AWS services. CloudWatch service was used for logs and monitoring (endpoints metrics, lambda performance, DB connections etc), setting alarms for different occasions.
