Project Summary

Squash Apps converted a prototype into a MERN-stack Progressive Web App that links notes and calendar functions to increase productivity, migrating infrastructure to AWS and iterating on functional enhancements. The app (Shelly) is live in beta with around 600 subscribers. The client praised Squash Apps’ engineering quality, communication, and affordability while noting UX capabilities are still developing.

Key Challenges

  • High Australian development labor costs and need for affordable, high-quality engineers
  • Convert an existing prototype into a robust, production-ready application
  • Validate product functionality without incurring the cost of native Android/iOS development

Project Deliverables

  • Progressive Web App (PWA)
  • MERN-stack web application
  • AWS-hosted database and server infrastructure
  • Migration of prototype to production-grade application
  • Project management and account management support

Project Solution

Squash Apps converted the client's prototype into a production-ready application by migrating it to the MERN stack and moving the database, server, and other infrastructure to AWS. They developed a Progressive Web App (PWA) to validate functionality while keeping costs low, implemented functional enhancements, and structured the codebase to allow future native apps using React Native. The vendor staffed the engagement with software engineers (initially three, ramping to six), one UX person, a project manager, and an account manager, and they coordinated work using Slack and Trello with weekly sprints and reviews.

Project Outcome

  • The solution is live and in beta with around 600 subscriptions
  • High-quality engineering output comparable to Australian agencies
  • Strong project management and communication using Slack and Trello with weekly sprints
  • Ongoing product advancement with active beta engagement
