    In my past life, I worked as Automation Program Manager for a large company (Market Cap $14B+), designing and managing VBA and Python-based tools, ultimately saving the company over $4M / year in increased efficiency. As I built more software automations, I watched more peoples' jobs vaporize in thin air... Eventually, I couldn't take it anymore. I didn't want my software skills to be used lining shareholders' pockets, while my co-workers lost their jobs. Then I realized: Rather than automating jobs away, I could free up small business owners to do what they're passionate about, instead. And so, here we are! This feels like a much better way to put good out into the world. I like to take on projects which excite me. I have over 15 years of web/software development experience under my belt, and love bringing that to the table to help people create new, awesome tools.

    I have ten years experience in geospatial data analysis and reporting, and three years in web applications development. In every office I worked, the data processing tools I developed significantly cut time spent on gathering and preparing data, while simultaneously improving the communication of that data among networked systems. Later on, I started focusing more on the web applications side of software development, especially with open-source technologies. Now I share my skills with the rest of the world as a freelance web developer. I am particularly skilled with presenting geospatial data on various maps like Google and Leaflet. I am also quite adept with regular expressions (pattern matching) for finding and extracting information from a wide variety of source formats. My curiosity and problem-solving skills make me great at coming up with cleverly simple answers to complex problems. Bring me your challenges; I'll provide you solutions!
