Project Summary

Solid Software built a custom web client for a financial services partner using Dart and Flutter to enable shared business logic across front- and backend. They defined system architecture, implemented automated testing, and integrated the platform with a SQL database and cloud microservices. The client praised the high code quality, clean architecture, and the vendor’s project management practices. The engagement ran from May 2020 to April 2021 and delivered tested, production-ready functionality.

Key Challenges

  • Improve engineering productivity by using a single language across front- and backend
  • Visualize enterprise data with charts and graphs
  • Deploy cloud-based microservices to handle data processing
  • Integrate with a new SQL database

Project Deliverables

  • Web client built with Dart/Flutter
  • Architecture and system design documentation
  • Automated test suite and testing frameworks
  • Integration with SQL database
  • Cloud-based microservices deployment

Project Solution

The vendor designed the system architecture based on an existing UI/UX design and built a web client using Dart and Flutter to enable shared business logic between front- and backend. They established testing frameworks and automated tests to maintain functionality as the platform grew, implemented integrations with a SQL database, and worked with cloud-deployed microservices for data processing. The team of nine (one engineering manager and eight engineers) executed feature development and followed defined design documents and clean-architecture practices.

Project Outcome

  • Improved visibility into team performance using Haystack (cycle time, throughput, deployment rate, change failure rate)
  • Delivered features on time by managing roadmap and breaking work into CapEx/OpEx tickets
  • Maintained high code quality and a clean, well-tested architecture
