ABOUT ME
I have over 20 years of experience in software engineering, specializing in data-driven web applications and web services using open-source technologies. I have expertise in and passion for data science and machine learning.
Due to a breadth of experience at start-ups as well as Fortune-500 enterprises, I have gained extensive experience in front-end / UI, database administration, design, and development, software architecture, infrastructure and systems administration. I care as much about the data processing and analysis pipeline as I do about a positive end-user experience. I have focused on content management systems, eCommerce and social network applications in the areas of telecommunications, education, medicine, entertainment, and social media.
