Safety Helmet Detection System Based on YOLO and Spring BootEnsured worker safety through camera-based detection & notification of workers without safety helmets.• Self-initiated project in which I recognized & implemented an opportunity to improve worker safety.• Implemented a YOLO detection model in a Flask (python) service in order to detect unworn helmets in video streams. Assigned a confidence value to the results and based notification logic on values.• Utilized RabbitMQ… Show more Safety Helmet Detection System Based on YOLO and Spring BootEnsured worker safety through camera-based detection & notification of workers without safety helmets.• Self-initiated project in which I recognized & implemented an opportunity to improve worker safety.• Implemented a YOLO detection model in a Flask (python) service in order to detect unworn helmets in video streams. Assigned a confidence value to the results and based notification logic on values.• Utilized RabbitMQ for message-based asynchronous communication to handle peak traffic shaving, effectively managing high-concurrency requests of over 10 video streams (each producing 10-20 messages per second) and thereby improving system reliability, stability, and scalability.• Integrated JavaScript-React- MaterialUI frontend and Java-Spring Boot backend for seamless functionality and improved product quality. Utilized: Spring Boot (Java), RabbitMQ, YOLO(Python), React (JavaScript), MaterialUI, MySQL, Flask (Python) Online Employee Training Platform• Designed and implemented a comprehensive React interface to facilitate the education and assessment of employees, both providing employee training and tracking learning progress.• Handled complex permissions requirements that involved differing levels of information access for employees across different levels of the organization.• Integrated Tencent's advanced Cloud Object Storage to ensure smooth access to video courses.• Integrated SMS messaging into user authentication to prioritize the security of users' accounts for a userbase of mineral miners relatively unfamiliar with email. Utilized: Tencent Cloud APIs, Spring Boot (Java), React (JavaScript), MaterialUI, MySQL Information Technology• Maintenance & configuration of company network, IoT/digital imaging tools, & messaging platforms.• Repair and replacement of hardware for automated tools, Wi-Fi/routers, and IoT devices.
