Onsite software engineer at Central Weather Bureau. Responsible for maintaining C++-based radar data processing system and develop meteorological information technique. Key Projects(Publication/Oral talk): Radar Data Quality Control based on Fuzzy Logic Algorithm on Taiwan Radar Network. A fuzzy-logic-based algorithm was developed to detect and remove unwanted non-meteorological signals, like interference pattern, arc artefact, ground and sea clutters, existed in Taiwan radar network.
