Project Details
Our primary responsibility during this engagement was to perform a code review cycle for the existing backend and mobile applications (both iOS and Android).
Problem
The client faced significant challenges, including:
- High escalation rates, with around 40 unique escalations per business day. Outdated infrastructure with no disaster recovery, auto-scaling, or CI/CD practices.
- Long load times, sometimes exceeding 3 minutes, leading to frequent timeouts.
- Numerous broken flows throughout the application.
- Lack of common modules, resulting in code reusability issues and repetitive code.
- Over 5 repositories that had not been reviewed, raising concerns about code quality.
Our Approach
We launched a 10-day code review sprint, during which we reviewed the applications and related repositories, checking code quality. Key findings included:
- No caching for frequently accessed data.
- Unoptimized code with insufficient comments.
- Absence of linting tools and pre-publishing checks.
- Lack of code reusability.
- Search results were returned directly from DB tables instead of using an ELK stack or similar practices.
- Over 250 feedback points per repository.
- Inadequate infrastructure, with no edge security, disaster recovery, or CI/CD setup.
- We provided solutions for these issues and were awarded the project to implement the necessary changes.
Benefits
Post-implementation, the changes resulted in:
- A reduction to 3 unique escalations per day, mainly for functional tasks. Significantly improved load times due to the implementation of the ELK stack and caching.
- Reduced loading times through multithreading, allowing components to load in the background.
- Adoption of best infrastructure practices, including CI/CD and disaster recovery, to prevent future setbacks.
- By addressing these issues, we enhanced the application’s performance and reliability, ensuring a better user experience.
