We reduced the change of having unknown/randomissues to 0 for new deployments.We changed from Flask to Django, DynamoDB to Postgresql/MongoSQL, session-id to JWT... etc togive the product more extensibility, stability, and scalability.The microservice structure gives us the ability to scale up the product and team easily while addingmore complexity to the developers' work. I'm trying to reduce the work complexity of developerswhile keeping the same productivity.After 2 months of working with the company product, I proposed to rebuild the system because I foresaw the system will fail after 6 months. The proposal is declined at the beginning but then approved 4 months later. Show less
