Project Summary

Qubika designed and implemented the backend architecture for a freelance developer's mobile app, delivering an Express/Node.js backend, PostgreSQL database hosted on AWS, and integrations with multiple AWS services. The team provided Postman QA artifacts, a Forest Admin dashboard, and technical documentation, and remained available for ongoing support. The client praised the code quality, responsiveness, and agile process and intends to work with the vendor again.
