    I excel at analyzing and manipulating data, from megabytes to petabytes, to help you complete your task or gain a competitive edge. My first and only language is English. My favorite tools: Tableau, Alteryx, Spark (EMR & Databricks), Presto, Nginx/Openresty, Snowflake and any Amazon Web Services tool/service (S3, Athena, Glue, RDS/Aurora, Redshift Spectrum). I have these third-party certifications: - Alteryx Advanced Certified - Amazon Web Services (AWS) Certified Solutions Architect - Professional - Amazon Web Services (AWS) Certified Big Data - Specialty - Amazon Web Services (AWS) Certified Advanced Networking - Specialty - Amazon Web Services (AWS) Certified Machine Learning - Specialty - Databricks Certified Developer:
 Apache Spark™ 2.X - Tableau Desktop Qualified Associate I'm looking for one-time and ongoing projects. I especially enjoy working with large datasets in the finance, healthcare, ad tech, and business operations industries. I possess a combination of analytic, machine learning, data mining, statistical skills, and experience with algorithms and software development/authoring code. Perhaps the most important skill I possess is the ability to explain the significance of data in a way that others can easily understand. Types of work I do: - Consulting: How to solve a problem without actually solving it. - Doing: Solving your problem based on your existing understanding of how to solve it. - Concept: Exploring how to get the result you are interested in. - Research: Finding out what is possible, given a limited scope (time, money) and your resources. - Validation: Guiding your existing or new team is going to solve your problem. My development environment: I generally use a dual computer-quad-monitor setup to access my various virtualized environments over my office fiber connection. This allows me to use any os needed (mac/windows */*nix) and also to rent any AWS hardware needed for faster project execution time and to simulate clients' production environments as needed. I also have all tools installed in the environments which make the most sense. I'm authorized to work in the USA. I can provide signed nondisclosure, noncompete and invention assignment agreements above and beyond the Upwork terms if needed. However, I prefer to use the pre-written Optional Service Contract Terms www [dot] upwork [dot] com/legal#optional-service-contract-terms.
