    "We were looking for some help standardizing and consolidating some data from several companies into one dashboard, but John showed us the true potential behind DOMO and it’s an understatement to say he’s been amazing to work with. He’s extremely accommodating, and we honestly couldn’t be happier with everything he’s done for us. We look forward to a long-lasting business relationship with him!" - Daniel G. Imagine never having to push a button again to get updates reporting updates and insights. I'm here to show that the world exists with Dashboaridng. While I do know Google Data Studio, Tableau and PowerBI, my main tool of choice is Domo. For instance, I had a client where an analyst spend 8 HOURS A WEEK just downloading data to then put together weekly reports. They brought me in, I hooked up different data sources like Google Analytics, Google Ads, Bing, etc and now those reports update each day and some update every 15 minutes. Not only did this save time for the analyst, but that allowed the analyst to spend time analyzing instead of stitching together reports. By hooking up a bunch of different, I've not only automated reporting for over 30 clients, but also saved them time need for Monthly Business Reviews, Board Meetings, Client Meetings, etc. My role is to be your dashboard guide and I'm happy to not only do the work for you, but to eventually train someone on your team to become the me of your team and I'm brought in for hardest challenges in the future. If you'd like to see more client reviews, examples of work and other offerings, you can do so at dashboarddudes.com I have a lot more stories like this that I'd love to share with you.

    My professional experience basically boils down to one thing... Automation. If you find yourself doing the same thing 5 times, that's 4 times too many. Whether it's: * Excel Spreadsheet Manipulation * PDF Parsing * File Management * Email Status Updates * Data Analysis * Web Entry/Scraping I have spent enough time doing things the long way to know it's the wrong way. Automation is the name of the game, and the more we automate, the more we can focus on what's important. * I pride myself on clean, well-tested code, and having a small technological footprint * I expect my code to work, and work well I am also interested in developing video games, but will work for cheap until I gain experience!
