I've made a career out of using data and statistical analysis to solve business problems, but I'm much more than a machine learning practitioner or SQL ninja; I'm a critical thinker and problem solver. I can't wait to learn about your needs and help you figure out how to solve your problems using the most up-to-date Data Science or Machine Learning tools. I have broad experience in Data Science, having seen many projects through from data collection to implementation. My skillset includes: - ETL, Database Architecture, Data Mining - SQL mastery using any dialect (MySQL, PostgreSQL, Microsoft SQL Server) - The Python Data Science Stack: Numpy, Pandas, SciKit-Learn, Matplotlib, Jupyter - Linear Regression, Logistic Regression, GAM Models, Econometrics - Clustering, PCA, Decision Trees and other simple Machine Learning - Complex Machine Learning models Such as Gradient Boosted Machines using XGBoost - Data Visualization in ggplot, Matplotlib, Plotly Express, Power BI, and Google Data Studio - Creating and hosting Plotly Dash and R Shiny Dashboards. Freelancing is about more than just having hard technical skills, however. Since 2019, I have been able to make a living as a full-time freelancer in no small part due to my ability to make my clients happy. In this regard I like to focus on: - Communicating in the way that works best for the client - Sending regular updates or deliverable prototypes as appropriate - Setting realistic time expectations - Clarifying project expectations early so the deliverable is what the client actually wants - Meeting deadlines (you'd think this one would be obvious!) If this list sounds like it may just be lip service, please take a look at my client feedback. I love the freedom that comes with freelancing, and I know the only way I get to keep doing it is if I have consistently happy clients. If you are looking for a Data Scientist, Data Analyst, or Machine Learning engineer, I really think I could be your guy. You've read this far you must be somewhat interested right? :) Go ahead and reach out or send me an invite to your project. I'll definitely get back to you asap and am excited to see if we can work together!

I’ve loved programming ever since Middle School. In high school I started to take more serious classes and then transitioned into a B.S and M.S program for Bioinformatics, allowing me to explore my love of genetics, programming and statistics simultaneously. Upon finishing my Masters I joined a PhD lab to do work in Social Media Analytics using Natural Language Processing. After several years of taking classes I was head hunted for a machine learning position with a private company and transitioned put of academy to pursue that career full time. I hope to use Upwork to continue to develop skills and explore fields I would be unable to at my full time position.
