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.

Check out my website for my resume, CV, blog, social media, and other resources: tinashemtapera.com I've been working with data for 8+ years in varying roles in both industry and academia. My background in psychology puts me in a unique position for data-driven decision-making, as it leads me to consider fundamental psychological mechanisms and behaviors that generate the data I analyze. In my PhD work, I study how individuals interact with their phones and other wearable devices and use the data collected by these devices to try and infer something about their mental health. Once we know our inferences are robust, we can then deploy technologies on their devices that predict what mental health state an individual is in throughout their daily life, and additionally deploy personalized, just-in-time interventions for them. I am passionate about data analysis and machine learning problems. If you have a data-related decision to make, I could be of help in various ways: - Data munging, wrangling, and cleaning, including the development of robust and reproducible data pipelines - Running descriptive and inferential statistics for simple to complex datasets and scenarios - Developing machine learning models to predict key variables and outcomes - Clearly and concisely communicating results of statistical or machine learning experiments - Packaging code, models, and reports at varying levels of reproducibility and containerization Don't hesitate to contact me to discuss how I can help you understand your data!
