Large-scale React application modernization
A major refactoring and quality program for a banking application, focused on maintainability, test coverage, and long-term delivery reliability.
Period2022–2023
Key outcome70% of the codebase refactored
The problem
A large financial frontend had accumulated technical debt that made changes slower and increased operational risk. Modernization had to happen while the application continued to serve its business users.
Execution
Kamal took ownership of the React and TypeScript application, upgraded its technical foundations, and refactored approximately 70% of the codebase.
- Introduced unit and integration coverage with Jest and React Testing Library.
- Reached approximately 70% automated test coverage.
- Added Cypress end-to-end scenarios to reduce regressions reaching production.
- Improved the development workflow while continuing delivery in an Agile team.
Outcome
The application became easier to maintain and safer to evolve. The engagement illustrates Kamal’s ability to modernize a business-critical frontend while balancing architecture, testing, and ongoing product delivery.
