Jennifer Heffernan is a Head of Data Science at Voicera AI. She possess expertise in c, matlab, java, c++, python and 14 more skills. Colleagues describe her as "I was Jennifer’s manager at Acquia for a year and a half. Jennifer was always very structured and analytical in her approach. She produced high quality work and her deliverables were complete (code, tests, runbooks, user documentation, presentations, etc). Jennifer worked on complex features that required extensive planning and, in some cases, required frequent communication with teams outside of the ML team. In her role, she has had to rapidly and successfully learn and leverage software such as Spark, Airflow, MLFlow or Jenkins. Jennifer has several years of experience working with AWS services and earned a couple of certifications. Overall, it has been a pleasure to work with Jennifer and I recommend her for any Data Scientist or Machine Learning Engineer position." and "I have been a professor at Stevens teaching required CS courses for almost two decades and Jennifer is clearly among the very best students I've had. She is hard working and smart. I recommend her without hesitation."
