<h2>Resolving App Battery Overconsumption Issue</h2>
<h3>Background</h3>
<p>    An issue occurred where the app excessively consumed battery under certain conditions, depending on the location permission state.</p>
<h3>Responsibilities</h3>
<ul>
<li>Analyzed and resolved the battery overconsumption issue using profiler and ADB tools — full analysis and development (100%).</li>
</ul>

<h2>Resolving App Slowness Issue</h2>
<h3>Background</h3>
<p>    Continuous customer service reports regarding the app’s slow performance.</p>
<h3>Responsibilities</h3>
<ul>
<li>Identified performance bottlenecks across the app, server, and database (100%).</li>
<li>Redesigned and optimized non-real-time features and related policies (100%).</li>
<li>Improved and optimized data query performance (20%).</li>
</ul>


This project tackled critical performance issues in an Android app. It first resolved excessive battery drain, caused by location permission handling, using profiler and ADB for analysis and resolution. Secondly, it addressed app slowness by conducting a full-stack performance analysis to identify and optimize bottlenecks in non-real-time features and data queries, resulting in a more responsive UX.

Resolved critical battery drain and app slowness. Fixed battery issue (related to location permissions) using profiler/ADB. Improved performance by optimizing bottlenecks across the app, server, and database.

Resolving App Battery Overconsumption & Slowness Issues

A service that collects in-store data such as Wi-Fi, Beacon, and ambient light through crowdsourcing. Contributors receive monetary rewards for their participation. To prevent abuse during data collection, photos of the store interiors are taken. Captured photos are stored in Firebase and undergo a final approval process via an internal review platform.
