💼 Project Achievements & Responsibilities

1. Software Development & Process Automation

• WPF SDK Development: Developed an Ultrasound Sensor Development Kit (SDK) using C# (WPF). Transformed complex firmware parameter settings, which previously required manual config file entries, into an intuitive graphical interface.
• Smart Calibration Mechanism: Designed an automated parameter adjustment process.
  • Solution: Guided users to perform specific gestures (e.g., swiping left/right) on the sensor, and the program automatically analyzed the waveform to find the most suitable filter frequency.
  • Results: Greatly simplified the tedious verification procedures required by differences in materials, hardware, and environments, significantly improving customer production line tuning efficiency and user experience.

2. Algorithm & Firmware Engineering

• Signal Processing: Conducted ultrasound signal analysis using MATLAB. Implemented noise filtering (including linear and non-linear filters) and developed touch algorithms to optimize gesture recognition accuracy.
• Firmware Implementation: Wrote firmware using C++. Ported optimized performance parameters and new features (such as virtual button trigger mechanisms) into the firmware, successfully integrating them into products like smartphones (e.g., ROG Phone) and laptop touchpads.

3. Global Collaboration & MP Support

• Technical Communication in English: Participated in weekly English technical synchronization meetings, collaborating closely with the US headquarters engineering team to ensure technical specification alignment.
• Mass Production Crisis Management: Served as a key technical contact during PVT (Product Verification Testing) and MP (Mass Production) stages. Quickly identified the root cause of anomalies reported by the production line and provided firmware fixes; established efficient analysis reports and escalation mechanisms for critical issues.
