    Hi! I'm Chris, a certified CMS/CRM Developer/connection specialist and Google Sheets/Appscript expert. I have been working within various CMS, CRM and Google systems for years, primarily Hubspot and Google Sheets. I have extensive experience in all aspects of these systems, including initializations and integrations, building pages and UI, implementing A/B testing, building robust workflows and more. I have managed various Business, Marketing and Sales initiatives, incorporating various platforms and features into a seamless, well-oiled machine. Why am I the right fit for you and your business? 1) I know Hubspot and Google Sheets like the back of my hand. If these systems can do it, I can build it. (I also have extensive experience with other similar or related platforms, such as Monday.com, Zapier, Make.com, etc) 2) My coding experience allows me to go further. I can often create functionality that isn't native to a system, side-stepping limitations and barriers that would often stop other developers. 3) Affordability: I have been subcontracting as a developer for years, but am new to the freelance scene. That is reflected in my current low rates as I introduce myself to the Upwork community. 4) I previously spent 10+ years in the games development market during which time I wore essentially every hat within the business, from project manager, chief coding officer and app developer, graphic & sound designer and even head marketer. That multi-roll experience gives me a shorthand for understanding the different needs between your creative, development, marketing and sales teams, and translating that into cohesive solutions. If you think I can help you with your project/s, please reach out. I'd be happy to chat for 15 - 30 minutes to discuss your project and demonstrate why we're the right fit for each other. Thanks for reading! Chris

    As a professional Zapier user for personal and business use, I recognize that one piece of software can't fix problems. What I can do is tie together your favourite software suites and have the data talking to each other. Use one app for time tracking, one for invoicing, one for accounting, and a final one for proposals without entering your data four times! I used to work in a consulting role at a small-business invoicing software, I have a BComm in entrepreneurship, and my focus is always to implement a solution that’s best for not just yourself but the business as a whole. With the hundreds of small business owners I have worked on projects with, I use that experience to educate you, apply those cases to your business, and work with you moving forward.
