&lt;p&gt;🔒 &lt;strong&gt;Repository is not yet public.&lt;/strong&gt; Project details below.&lt;/p&gt;
&lt;/blockquote&gt;
&lt;h2 id="project-overview"&gt;Project Overview&lt;/h2&gt;
&lt;p&gt;Comprehensive management platform for medium-sized nursing homes with both &lt;strong&gt;B-end operations dashboard&lt;/strong&gt; and &lt;strong&gt;C-end family mini-program&lt;/strong&gt;. Covers health assessment, IoT device monitoring, and nursing work orders.&lt;/p&gt;
&lt;p&gt;Team of 6 developers; responsible for the &lt;strong&gt;health assessment engine&lt;/strong&gt;, &lt;strong&gt;IoT sync service&lt;/strong&gt;, and &lt;strong&gt;unified authentication&lt;/strong&gt; modules, serving 500+ devices and 2000+ daily family visits.&lt;/p&gt;
&lt;h2 id="core-responsibilities"&gt;Core Responsibilities&lt;/h2&gt;
&lt;h3 id="1-health-assessment-module-development--performance-optimization"&gt;1. Health Assessment Module Development &amp;amp; Performance Optimization&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;Integrated &lt;strong&gt;Baidu Qianfan AI model&lt;/strong&gt; for semantic analysis of health reports&lt;/li&gt;
&lt;li&gt;Designed &lt;strong&gt;Redis multi-level caching&lt;/strong&gt; for frequently accessed health advice&lt;/li&gt;
&lt;li&gt;Reduced single analysis response from &lt;strong&gt;8s to under 1s&lt;/strong&gt;&lt;/li&gt;
&lt;li&gt;Improved nurse review efficiency by ~&lt;strong&gt;30%&lt;/strong&gt;&lt;/li&gt;
&lt;li&gt;Effectively supported high-concurrency queries during peak morning hours&lt;/li&gt;
&lt;/ul&gt;
&lt;h3 id="2-iot-device-management-module-design"&gt;2. IoT Device Management Module Design&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;Developed &lt;strong&gt;Huawei Cloud IoT platform&lt;/strong&gt; integration service&lt;/li&gt;
&lt;li&gt;Incremental sync of product lists via async thread pool&lt;/li&gt;
&lt;li&gt;&amp;ldquo;Device-Location&amp;rdquo; binding logic for data consistency&lt;/li&gt;
&lt;li&gt;Sync time reduced from &lt;strong&gt;3 minutes to 10 seconds&lt;/strong&gt;&lt;/li&gt;
&lt;li&gt;Real-time monitoring of &lt;strong&gt;500+ devices&lt;/strong&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;h3 id="3-security-authentication-system"&gt;3. Security Authentication System&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;Interceptor + &lt;strong&gt;ThreadLocal&lt;/strong&gt; based seamless login for WeChat mini-program users&lt;/li&gt;
&lt;li&gt;Multi-thread data isolation and security&lt;/li&gt;
&lt;li&gt;Zero memory leak stable operation&lt;/li&gt;
&lt;li&gt;Supporting &lt;strong&gt;2000+ daily&lt;/strong&gt; active visits&lt;/li&gt;
&lt;/ul&gt;
&lt;h2 id="project-results"&gt;Project Results&lt;/h2&gt;
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;Performance&lt;/strong&gt;: AI analysis response reduced from 8s to under 1s&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Sync&lt;/strong&gt;: IoT device list sync from 3min to 10s&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Scale&lt;/strong&gt;: 500+ devices real-time monitoring, 2000+ daily visits&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Stability&lt;/strong&gt;: Zero memory leak, stable production operation&lt;/li&gt;
&lt;/ul&gt;
