During December 2025, Popica delivered asynchronous network configuration and over-the-air update management for ESP32 and ESP8266 devices within the arduino/library-registry repository. He integrated AsyncWiFiManagerSimple to enable non-blocking WiFi provisioning and added AsyncOTAManager for secure, authenticated OTA updates with auto-detection. His work included implementing captive portal flows, dynamic WiFi scanning, multi-network storage, and automatic reconnect features, all leveraging C++ and JSON for embedded systems and IoT development. By updating repository metadata and dependencies, Popica improved library discoverability and compatibility, demonstrating depth in device control and embedded software engineering focused on reliability and streamlined deployment for IoT applications.
