Work Experience
Principal Software Engineer
Western Digital Technologies•  June 2010 - Present•  Thailand
* Designed and developed automation platform for HDD head manufacturing process. * Proposed a custom information sharing protocol using structured text formats: specifically, customized CSV and XML, used for data exchange between process devices and the database server. * Leveraged TIBCO Spotfire, a leading business intelligence platform widely adopted by enterprises, to create engineering dashboards that not only helped uncover and interpret hidden process information from the database, but also utilized the platform's auto-alert feature to send automated daily email reports on production outputs, yields, and top defect pareto. * Evaluated the feasibility of integrating an advanced closed-loop control technology with WD's legacy equipment by exploring the use of Kepware and ThingWorx's commercial IoT platform to enable IoT capabilities for the existing legacy system. Kepware was leveraged to facilitate the translation of communication protocols between various industrial devices and ensure seamless data exchange between the devices and ThingWorx. ThingWorx provided the core components and services for analyzing the device data. * Initiated a proof-of-concept for closed-loop control by adding IoT capabilities to the legacy adhesive dispensing tool in the HGA process. Created a low-level software interface to facilitate data exchange between device sensors and ThingWorx. Employed a well-trained and deployed machine learning model on ThingWorx to receive data from device sensors and predict optimal parameter adjustments for improved process stability. This involved processing signals from device sensors, such as pressure and timing intervals for opening and closing the valve, to achieve optimal adhesive volume. * Evaluated the potential of an AGV platform to enhance material logistics automation. The evaluation revealed that the AGVs are capable of seamlessly assisting with material movement between workstations and automating data exchange between the MES (Manufacturing Execution System) and frontline personnel. This finding suggests significant potential for efficiency improvements. Successfully delivered the first AGV deployment at WD's Philippines HGA factory. * Ensured data traceability for HAMR FA works; leveraged cost-effective, homegrown software development utilizing the powerful AForge.NET open-source library for image processing tasks. The C#.NET software extracted data matrix barcodes and decoding pattern mark IDs from images, enabling efficient traceability back to supplier information.
Software Engineer
