---------USING AI/ML TO HELP BUSINESSES GENERATE VALUE FROM THEIR DATA ---------
If you're looking for assistance in capturing, analyzing, or modeling your data, you've come to the right place. I live and breathe data, and have spent the last decade refining my ability to create value from it.
I previously served as a Data Science Consultant for Snow Fox Data, where I used Python/Dataiku every day to help international brands leverage AI and unlock the full potential of their data. In addition to roles in fintech and edtech, I also served for several years as an optimization analyst at a growing advertising technology startup, helping brands like eHarmony, Wayfair, Fandango, Ancestry, and Thrive Market to maximize the value of their web campaigns. Within my own data consulting company, I've partnered with companies across all primary domains, including a major global sports league and their partner agencies in order to analyze the impact of COVID-19 on user engagement. I've also partnered with health systems managers to optimize their operations, tech researchers to help design and analyze survey data, investment firms, educators, and logistics coordinators, just to name a few.
--------------------------------------AS AN EDUCATOR--------------------------------------
Going back to 2015, I have worked with students of all ages to develop a statistical and mathematical skillset, especially for those that are looking to make a career change. From January - June 2020, I functioned as a Teaching Assistant at the NYC Data Science Academy, where I led classes/review sessions for 100+ students on data structures & algorithms in Python, R programming, data visualization, hypothesis testing, linear and logistic regression, tree-based models, support vector machine, and other key data science concepts. Most recently, I functioned as a Primary Fintech Instructor for an extension course at The University of Pennsylvania, where I worked with dozens of students to develop their programming, mathematical, and overall data-oriented skills as it ties into the world of finance and fintech.
----------------------------------------AS A MENTOR----------------------------------------
I've worked one-on-one with over a dozen students to develop a comprehensive plan on transitioning their careers to data science. Additionally, I've provided services to prospective data scientists via resume review, interview preparation, and as a general go-to for data science questions and knowledge on the overall landscape. I currently serve as a mentor on MentorCruise, where I meet regularly with students to discuss their goals and review their progress.
----------------------------------------BOTTOM LINE----------------------------------------
Whether you're a business that wants to gain a substantial edge in the budding world of artificial intelligence, or a potential data scientist that wants to learn skills or break into the field, I will use everything in my arsenal to generate value, insights, and an actionable deliverable that will help you keep you or your business ahead of the curve. I'm highly responsive, so reach out today -- I'm happy to help.
