Shopify and full-stack developer with over 14 years of experience, customizing and optimizing websites! Currently focusing on the ever-growing and powerful Shopify platform. Shopify is an incredible eCommerce solution "out of the box". However, there is much customization that can be done to make the end product truly fit your brand. I am also heavily involved in API development. I mainly stick to the Node/Express (JavaScript).

Regarding desktop I have focused on using C# in the .NET environment, to build a variety of native Windows applications. I also use Electron on occasions that call for a simple desktop integration from an existing web app. It has proved to be an effective and secure solution when used correctly.
