Modernizing a Carbon Credit Platform

At Six Feet Up, we favor solutions that can scale and adapt to change. We initiated the project by leveraging Docker containers for efficient local development, enabling our client to use similar for deployment as well. The existing PostgreSQL database from the Rails project was retained, ensuring seamless data transition.

Initially, we planned to translate Rails code to Python/Django directly. However, with the client's decision to switch to a React frontend, we revisited our strategy. Instead of rigid code translation, we adopted a User Stories-driven approach that prioritized business objectives. This shift allowed us to zero in on end-user needs, ensuring the resulting application was both functional and aligned with user expectations.

The project unfolded in two key phases:

• Phase 1: Six Feet Up spearheaded the development, understanding the business requirements and constructing business-first User Stories that set the project's direction. Specifically, our team:
  • implemented pre-commit and CI workflows for testing, linting and typechecking;
  • developed the backend using REST API and enhanced Django's best practices for API design, including conducting a deep-dive into the pros and cons of REST vs. GraphQL;
  • created a modern web app using React, TypeScript, Vite, React Router DOM, Material UI, Recharts;
  • used Vitest, Jest and Mock Service Worker (MSW) to create tests;
  • completed extensive testing on both the backend and frontend.
• Phase 2: As the client's Rails developers started assimilating into the new system, we shifted towards a more advisory position, providing mentorship and conducting code reviews.

The pivot to a User Stories approach, which afforded a clearer understanding of the business needs, was a significant milestone for our team and the overall success of the project. While challenges — including deployment restrictions due to a recent acquisition — occurred, we worked collaboratively with our client to deliver a modern web app that meets their goals.
