Senior🎓
Top SchoolAlan Reiner is a Senior Machine Learning Engineer with 15 years of experience blending physics-grade rigor and production ML to solve hard perception and security problems. A former rocket scientist and physicist at JHU Applied Physics Laboratory, he has deep expertise in computer vision, optics, and simulation-driven modeling applied to surveillance, drone video, and few-shot image tasks. At Novetta he led IR&D efforts that adapted generative and multimodal techniques (DALL·E, CLIP) for dataset augmentation, developed pre-ChatGPT multi-document summarization, and built NLP-to-database translation systems for complex backend interactions. He also brings practical cybersecurity and backend experience—authoring features for the Python Bitcoin Armory project and consulting via Toptal on AI and data science. Alan combines academic training in applied and computational mathematics with entrepreneurial product delivery from founding Armory Technologies, making him equally at home in research prototypes and production pipelines. Based in Fulton, Maryland, he applies a scientist’s curiosity to pragmatic ML engineering, often turning domain physics into robust data-driven solutions.
