Summary
🤩
Rockstar🎓
Top SchoolAaron Sarna is a Senior Software Engineer based in Cambridge, MA with six years of professional experience blending web development, browser extensions, and machine learning research. Currently at Google, he applies practical ML engineering to computer vision and NLP, contributing notable improvements to high-profile Google Research projects like SupCon and the Scenic JAX library (adding optimizers, fixing activations, and improving checkpoint resumption). His background includes shipping popular cross-browser extensions (Forecastfox) and low-latency systems work from internships in HFT and web infrastructure, giving him a rare mix of front-end UX, systems performance, and ML model-tuning expertise. Comfortable across the stack, he focuses on reproducible training, optimizer and hyperparameter work, and browser-native UX. Collected studies in CS, cognitive science, and Near Eastern studies hint at a broad intellectual curiosity that informs both product thinking and research-driven engineering.

Role in this project:ML Engineer
ML EngineerContributions:5 commits in 1 month
Contributions summary:Aaron contributed significantly to the SupCon (Supervised Contrastive Learning) project within the Google Research repository. Their work focused on fine-tuning hyperparameters, including learning rates, weight decay, and optimizer parameters (RMSProp and LARS), across multiple ResNet architectures (ResNet50, ResNet101, ResNet200) for the ImageNet dataset. The user also addressed software compatibility and bug fixes as well as updating and adapting loss functions.
