Experience
Development of a Stock Management App
An app for managing stocks developed with Laravel on the back end and React on the front end. I built a small application with a few reports that allows small local businesses an easy cloud solution for their stock management. It also allows multiple users for easy sales tracking and detailed reports based on categories.
CRM for the DACH Region
A project where I contributed as a full-stack developer, constantly creating new features. The main issue with the application was that all its main features were built in AngularJS, and we slowly converted to React. I was also a part of the team that built the automation module, which allowed for some neat functionalities that gave users a lot of value, for which we received a lot of praise.
Development of a Professional Certification Application
A huge professional certification application built in an old PHP framework. The app was appointed to the team, and we converted everything module by module, also creating new features that improved the user experience.
