Project Summary

Yellow repaired and upgraded a previously mishandled iOS application and developed an AWS-based MVP web platform, migrating the database from SQL Server to Amazon Aurora MySQL. They implemented a scalable AWS stack (CloudFront, CloudFormation, VPC, EC2, S3, IAM, Lambda, DynamoDB), CI/CD pipelines and a custom API. The platform was delivered ahead of schedule and under budget, and the client praised Yellow's project management and ability to work at a startup pace.
