During my full-time work at Upshift, I had the opportunity towork on a diverse range of tasks. This included creating websocket events to enable real-time functionality, implementinglogic updates for already implemented features, and developing a feature that allowed users auto-favoring ofbusinesses. Additionally, I was involved in resolving bugs,making updates to the notifications and improving the overallcodebase by refactoring scopes and queries into queryclasses, as well as refactoring listeners and their events intojobs. Throughout my time at Upshift, I also learned aboutSegment and its event tracking capabilities to enhance theapplication's analytics and insights.

During the initial phase of my part-time job, I learned about theimplementation and progressed to working on minor bugfixes, improvements, and notifications. As I gained experience,I took on more challenging tasks such as resolving a bit moreserious bugs, writing complex queries, and creating reports. Ialso collaborated with colleagues from the frontend andmobile teams to implement a geofencing feature, allowingusers to clock in and out of shifts within a defined range.

During my internship, I had the opportunity to gain hands-onexperience and expand my knowledge in various areas of webdevelopment. I learned about the HTTP protocol, PHPprogramming, databases, the Laravel framework and Jira andSlack as collaboration tools. Working on a career progressionbackend application, I delved into models and theirrelationships, services, API controllers, authentication,authorization, validation rules, traits, notifications and cronjobs
