App Revamp & Codebase Rewrite, MVP Builder

Certifast Case Study

Certifast is a web based design app for creating design in bulk automatically, the MVP was built in 2021, but as the codebase grow it's getting harder to add new features. In 2024, we rebuilt the app from scratch to make it easier to develop new features and maintain the codebase.

History

Created in August 2021 with an outdated technology stack.

The focus was on functionality over code quality, leading to maintainability issues as features were added. Development stopped in January 2022 due to lack of traction.

Certifast Analytics March 2022

Certifast gained unexpected popularity on social media in March 2022.

User base remained stable despite no new features being added, prompting monetization discussions in December 2023.

Key considerations during the rewrite included choosing easy-to-maintain technologies and leveraging libraries for complex interactions (Moveable and react-zoom-pan-pinch). Valtio was chosen for complex client-side state management.

Rethinking Certifast After User Growth

The decision to rewrite Certifast from scratch was made in January 2024 due to a difficult-to-maintain codebase and the need for new features.
After rewriting, the team focused on re-architecting component interaction management and the undo/redo functionality.

Rebuilt, Refactored, and Ready to Grow

The rewrite took one month, and adding new features became significantly faster and easier. Within two months, more features were implemented than ever before with the old codebase

Fullstack TypeScript allows for a unified development experience using the same language for both front-end and back-end.
