The Challenge
Expensify's Share Code feature was presenting a disruptive visual and functional bug — ticket #40546 — in which the platform's 'E' logo was rendering at the centre of the generated QR code rather than in its intended position or not at all in certain rendering contexts. The issue was directly affecting end users who relied on the Share Code flow to share expense information quickly and accurately. With multiple users impacted and no clear root cause documented, the client needed a developer who could move fast, trace the problem through the codebase precisely, and deliver a clean, reliable fix without introducing regressions elsewhere in the application.
Our Approach
Helion360 began by conducting a focused audit of the QR code generation logic within the Share Code feature, isolating the component responsible for embedding the logo overlay. The investigation traced the issue to how the logo asset was being positioned relative to the QR code matrix — a combination of incorrect offset calculations and a z-index or layering conflict that forced the 'E' logo to default to a centred, uncontrolled position under certain render conditions. Once the root cause was confirmed, a targeted patch was written to correct the positioning logic, ensuring the logo rendered consistently across device types and screen sizes. The fix was implemented with attention to maintaining the overall code quality of the surrounding module, following clean coding conventions to prevent similar issues from arising in adjacent features.
The Outcome
The fix successfully resolved issue #40546, eliminating the incorrect logo placement across all tested environments and restoring the Share Code QR feature to its intended behaviour. The corrected implementation was verified against multiple use cases to ensure no side effects were introduced into the broader Expensify codebase. In addition to the fix itself, the team provided documentation notes on the root cause and recommendations for more resilient logo-overlay handling in future QR code generation scenarios — giving the client a stable foundation and clearer guardrails for ongoing development.
Helion360 brings the same precision and efficiency to technical debugging engagements as it does to brand identity systems — if your product is carrying an unresolved bug that needs a clean, fast resolution, the team is ready to help.
