Seyun Jeong developed and enhanced hardware integration features for the oss-slu/Pi4Micronaut repository, focusing on embedded systems and IoT device control. Over four months, Seyun delivered robust HTTP-based interfaces for hardware components such as a Seven Segment Display and Fan Controller, emphasizing maintainability and clear API documentation. Using Java and Pi4J, Seyun refactored controller logic for granular hardware control and streamlined configuration, while also improving onboarding through comprehensive AsciiDoc documentation. To ensure reliability, Seyun implemented extensive unit testing with Mockito and JUnit, increasing test coverage for core helpers and hardware input paths, which reduced regression risk and improved code quality.
