Digitalized the Maintenance Request System: Replaced traditional paper-based systems with a digital workflow using MS Forms and Power Automate. Real-time Notifications: Integrated automated alerts into MS Teams, allowing technicians to receive and accept repair jobs instantly via mobile devices. This significantly reduced response times. Data Visualization & KPI Tracking: Developed Power BI dashboards to monitor maintenance status and track performance. Replaced manual paper counting with automated data retrieval from SharePoint lists. Asset Management Application: Created a custom Power Apps application for asset tracking to replace manual logs. Improved data entry speed with auto-fill features and ensured easier data processing. Performance Improvement: Successfully increased team performance, resulting in technician KPI rates that exceed organizational targets through efficient digital workflows.

Test Requirement Analysis: Collaborated with international customers to define test specifications for PCBAs, including FCT/ICT requirements, circuit parameters, and communication protocols. Custom Test Hardware Design: Designed and developed customized Relay Control Boards using Arduino (C/C++) to automate test point switching and signal routing for Jig & Fixtures. Automated Test System Development: Developed comprehensive automated test solutions using LabVIEW to control high-end measurement tools (Keysight/Agilent) via communication ports. Data Integration & Quality Control: Implemented automated data logging to SQL databases, comparing real-time test results with Min/Max parameters to ensure 100% product accuracy and reliability. Production Optimization: Streamlined testing processes for high-volume orders (1,000+ units), significantly increasing throughput compared to manual testing. Technical Troubleshooting & Yield Improvement: Analyzed root causes of test failures and performed PCBA debugging to maximize production yield and meet delivery targets.

Firmware Development (C/C++): Developed and optimized firmware for 8-bit to 32-bit microcontrollers (STM32 Cortex-M, AVR ATmega) for automated machines such as smart coin changers and vending machines. Hardware & Software Co-Design: Collaborated with the R&D team to design control circuits and implement firmware functions based on customer needs and user experience (UX). Protocol Reverse Engineering: Analyzed and decoded industrial laundry machine protocols using Oscilloscopes to extract data such as coin counts and machine modes (Quick Wash, Dry, etc.). IoT System Integration: Filtered and processed machine data for back-end integration, enabling real- time monitoring of revenue and machine status via web and mobile applications. Product Innovation: Enhanced product features with interactive standby modes (LED indicators andstatus displays) to improve user engagement and customer satisfaction. Full Product Lifecycle: Managed the development process from initial concept and debugging to final testing, ensuring high-quality, market-ready products.
