Enabled 6-camera input at 20 FPS with an overall latency of 125ms or less, ensuring a high-performance, low-latency real-time perception pipeline. •Developed cutting-edge ADAS perception software capable of processing 4K images at 20 FPS with a latency of 125ms, even in most complex scenarios. •Optimized algorithms and functions, reducing CPU load by 50%: Enhanced 'FindLocalMinimum' function, decreasing average processing time from 4.3ms to 1.6ms. Improved NMS function efficiency from 9ms to 7.2ms on average. Optimized tensor memory traversal sequence, reducing processing time from 5ms to 1.2ms. •Implemented a profiling system within the perception software to provide detailed metrics, including frame processing times for each node, frame latency, and function-level time costs, enabling 40% faster identification and resolution of performance bottlenecks. ### Software Engineer @ ScaleFlux Jan 2018 – Present • Refactored the validation module for data compression and decompression, encryption and decryption using C/C++. And improved the performance by 500%, specifically from 500MB/s to 3GB/s by creating multiple threads to send commands in two command pools, and introducing batch processing of commands. • Led a company-wide project of code coverage test using Gcov as a core tool, which makes our product significantly solid and robust. • Designed and implemented Manufacture Acceptance Testing Tools via Agile development methodology with integration of business requirements from hardware and marketing perspective. • Developed Automation Tools from ground up which provides 90% above metrics in traceability reports using Python and Shell Script. • Redesigned and refactored the legacy test code bases which extended the capacity to support 24 SSD testing simultaneously, improved the production process efficiency by 80% and optimized the scalability and maintainability of the testing cases. • Built up a GUI and log system to improve the readability, key performance indexes analysis and debug efficiency for testing result, supporting the high-level product, marketing decisions and providing supportive data at P0 (product planning and marketing) and P1 (product design input) stage of the product lifecycle. • Took charge of Jenkins CI/CD pipeline to handle daily regression tests. ## Education ### Master's degree in Computer Science University of Dayton ### Bachelor of Engineering (BE) in Mechanical and Electrical Engineering Chang'an University ## Contact & Social - LinkedIn: https://linkedin.com/in/weifan-wang-353099135 --- Source: https://flows.cv/weifan JSON Resume: https://flows.cv/weifan/resume.json Last updated: 2026-04-10
