   Senior Fullstack Developer

   Microniq Business Automation AB

   As part of a team, I work on developing a resource planning system that helps cleaning companies run more efficiently and simplifies their workflows. We tackle both the frontend and backend to create a solution that’s both reliable and easy to use. The frontend is built with React and Material UI, offering a clean, user-friendly interface, and we use Auth0 to make sure authentication is secure and simple.
   
   On the backend, we’ve put together a solid system using a PostgreSQL database and a REST API built with Express.js. We’ve also integrated the Fortnox.se API to automatically sync financial data with internal records. Real-time updates through WebSockets ensure users always have the latest information at their fingertips. The system cuts down on manual work and helps businesses save time while staying productive.

   Senior Fullstack Developer

   Trackpaw Scientific AB

   I developed the Vue.js application for the surveillance system for lab rats. The frontend application was integrated with the backend, which read the data from sensors located on the floor of the cages, where the lab rats lived. In this role I had a broad responsibility within the frontend development. I set the structure of the application and developed it solely on my own. My role also required me to take UI/UX decisions to develop the design.
