The Challenge

📌 Subscription System Generation: Implementing a subscription system posed our initial challenge. Despite its complexity, our team navigated this task adeptly, finalizing the system smoothly to enhance user engagement and loyalty.
📌 Shopify API Integration: The second challenge involved working with Shopify’s API. Understanding the intricate requirements and seamlessly integrating them into the final project demanded a strategic approach and precise execution.


✔️ Subscription System Optimization: To overcome the complexity of the subscription system, our team opted to leverage our own database system instead of relying on Shopify’s database. This decision not only simplified the implementation but also ensured a more tailored and efficient subscription experience for our customers.
✔️ Shopify API Customization: For working with Shopify’s API, our team meticulously tailored the integration to meet project-specific requirements. By understanding and addressing the unique demands of SlikEkspressen, we crafted a solution that seamlessly integrated with the existing ecosystem.


✏️ Requirements Gathering and Backlog Creation: The project commenced with a thorough requirements gathering phase. We meticulously identified and documented the project’s needs, breaking them down into product backlogs, and further into tasks.
✏️ Agile Planning and Scrum Methodology: Following Agile principles and Scrum methodology, we planned sprints with a focus on prioritizing tasks. The highest priority tasks were allocated to the initial sprint, ensuring a strategic and iterative development process.
Collaborative Tools: Confluence was employed for documentation, Bitbucket for repository and version control, and Slack along with Google Meet for seamless communication. These tools facilitated efficient task management and ensured a collaborative workflow.
