Yes, during development of the Tinder for Roommates app, I was responsible for testing the swipe functionality and user profile matching. One bug I encountered involved the app crashing when swiping right on certain user profiles. Here's a summary of the QA report I documented:

Title: App crash when swiping right on specific profiles Environment

Steps to Reproduce: Log in with any user account. Navigate to the swipe screen. Swipe right on profiles with incomplete bios

Expected Result: User is added to match queue and taken to chat preview

Actual Result: App freezes and crashes after swipe right

Console Error: bashCopyEditTypeError: Cannot read properties of undefined (reading 'roomType')

Root Cause: The matching logic did not include null-checks for optional profile fields. Attempting to access .roomType on undefined triggered a crash.

Solution Proposed: Add null-checks in the match prioritization algorithm

When identifying bugs, I start by thoroughly testing the product to replicate the issue. I work backward to isolate the root cause and debugging the logic layer by layer. Once I’ve pinpointed the issue, I document it clearly, including steps to reproduce, expected vs. actual behavior, environment details and relevant screenshots or logs. This way, developers can efficiently understand and resolve the problem. I also track patterns in issues over time to help inform broader product improvements.
