We can modify if any feature is not working as expected or if a new feature is to be added to enhance UI/UX by doing a thorough code review, checking technical functionalities, understanding how modules are interacting, and so on. We additionally manage code readability for future needs and latest version control.
We identify the bug and try to fix it from the backend instead of making changes in multiple platforms (iOS/Android individually) to save time and avoid version updates on the store for minor changes/bug fixes. We then find the route course of the bug and fix it permanently by applying the relevant solution.
We use GT Matrix & Google services to check the performance and responsiveness of the app on various devices across browsers. We then remove unnecessary JS and CSS images for query optimization, minimize long/unnecessary responses generated from API for quick turnaround of data display & reduce load time.
