Hi, I'm Ben! I enjoy writing machine learning systems and software to drive growth.My favorite ML subjects are text (LLMs/transformers), recommenders, search, time series, and computer vision. I have over 5 years of experience in Python including common ML libraries and corresponding technology to get models shipped into production in real-time or batch. I am comfortable with mlflow, pyspark, pytorch/tensorflow, latency/performance tracking, model API deployment/consumption, permission handling, CLI/shell, Git, Docker/VCS, AWS (Airflow, lambdas, Sagemaker, etc.), and cluster configuration for CPU, GPU, and TPU in the cloud.Some data science projects I back in grad school (2022): https://github.com/benmerrilllP.S. Hot take: Functional programming > OOP in products, OOP > Functional in ops ;)
