Work History
Software Engineer – Machine Learning (Project)
University of Massachusetts Amherst
09.2024 - 05.2025
- Designed and trained multi-class machine learning model for time-series classification of IMU sensor data, achieving 93% accuracy and a 93.8% overall F1 score across five gesture classes.
- Developed a custom data pipeline with 1,700+ labeled samples, including preprocessing, temporal feature extraction, and train/test evaluation.
- Deployed optimized TensorFlow Lite inference pipeline to ensure real-time performance (~2 ms average inference time) on production hardware.
- Integrated end-to-end ML system from sensor data acquisition to inference and real-time audio feedback on a Linux-based platform.
Software Engineer (Systems)
University of Massachusetts Amherst
02.2024 - 05.2024
- Developed a user-level thread library in C++, incorporating a custom scheduler to manage concurrent execution.
- Designed synchronization primitives to ensure correct shared-resource access, preventing race conditions and deadlocks.
- Implemented a disk request queue using the Shortest Seek Time First (SSTF) scheduling algorithm for efficient I/O request management.
- Validated correctness of concurrent behavior using extensive automated test suites with limited diagnostic feedback, iteratively debugging synchronization and scheduling edge cases.
