My contribution to the development of Mailchimp Open Commerce (formerly Reaction Commerce), including to significant updates such as the release of version 3.0, where the introduction of a headless GraphQL API played a key role, has been acknowledged on GitHub in a thank you note (github.com/reactioncommerce/reaction/releases/tag/v3.0.0) as well as by a testimonial on the official landing page (mailchimp.com/developer/open-commerce). Additionally, I have actively engaged in virtual community meetups and exchanged ideas with developers. Beyond that, I continuously strive to contribute to open source projects that I use professionally or privately, thereby actively shaping the software landscape.
