GoCancel is a cancellation platform helping thousands of customers each day to cancel any of their subscriptions. The platform is centered around a uniform API built on REST principles and activities for all customers within the European Union. That way, integration partners are not bothered with implementation details, like which cancellation method to use for a specific company. Everything is abstracted away and automatically processed through several sending methods, like email, post, and even fax. As the platform is completely event-driven, partners can hook into every step of the cancellation process through the use of webhooks.

As the CTO of the company, I designed and built the initial foundation of the platform. I helped the first B2B partners integrate through the API and iterate its specs from their feedback. I also architected an event-driven system that allows cancellations to be sent through multiple sending services for specific European countries and their requirements, such as DeutschePost, La Poste, and PostNL.
