    Hello UpWork! My name's John and I design and code. I can work on print and web and mobile and apps. I've been freelancing professionally since 2005, and have handled anything my clients needed, most of whom I've been serving for 10+ years. I'm new to UpWork and looking to build a solid reputation here. I earned a BFA in Graphic Design from San Jose State University that was very focused on Form Follows Function [Bauhaus] design philosophy with a strong emphasis on traditional typography. This essentially means that the look and feel of any design should not get in the way of delivering its message, or performing its function. And these same principles find their way into my thinking and decision making for presentations, flyers, information design, and any other graphic I design. I'm based out of North County, San Diego, CA; and am always on the lookout for opportunities to significantly help other entrepreneurs, businesses, and organizations grow and build amazing things.

    Best Google Sheets pro on Upwork. Read my reviews. Save yourself a great deal of time and money - almost half of my jobs have been to fix the work of other Google Sheets freelancers. I provide unparalleled A+ quality work that is optimized to scale with any amount of data. All of my code is neatly formatted and provides detailed in-code documentation which will allow you, your team, and future contractors to easily understand how it works. I have received a superb rating from every single client of mine and plan to keep it that way. I will make sure your vision is masterfully executed. I am a master of advanced Google Formulas and Google Apps Script (the code that runs services like Google Sheets). I am able to connect to external APIs, create Dashboards, Data Visualization & Analytics, and more. I have experience managing data from services such as Quickbooks, PayPal, Microsoft Excel, SalesForce, Zoho, Cryptocurrency Exchanges, and many others.

I have a Bachelor of Science in Computer Science from California State University, San Marcos, and hands-on experience from my software engineering internship at Amazon. I have also completed coursework in a range of areas, including embedded systems, cloud computing, and software engineering. Throughout my academic and professional career, I've had the opportunity to work on a diverse set of projects, from developing Alexa skills that reduced Bluetooth latency to creating a point-of-sale system using Typescript and GraphQL. I've worked on web development, embedded systems, and full-stack development projects. I enjoy staying up-to-date with the latest advancements in technology and am always eager to learn new things.
