In my previous role at a startup, I was the sole Android Engineer responsible for the native mobile apps. I had the opportunity to create a new Android app. It was an app that allowed warehouse workers to scan barcodes on packages to create an electronic chain of custody. The client who requested this app was happy with the results. I exceeded expectations by delivering the app ahead of schedule (2 weeks vs. 1 month). The necessary features were in place, and the app was user-friendly. https://play.google.com/store/apps/details?id=ai.beans.isp.scan

Cover image for I recently watched a video

I recently watched a video of someone going on a trip to see the Northern Lights. At the end of the video, the person showed a timelapse of the Northern Lights, and I was in awe. Given the holiday season, I was curious to see what a Christmas tree under the Northern Lights would look like. I was able to find the following image (https://media.istockphoto.com/id/2224224036/photo/aurora-borealis-northern-lights-over-christmas-tree-strong-aurora-storm-yellowknife-northwest.jpg?s=612x612&w=0&k=20&c=1folij9hCKe3GGvXlHLu171g2uR_zUl52KZmNsGufPI=). I used this image as inspiration to create a festive EDM song on Suno: https://suno.com/s/y8UK3O8PNWftC0E9 With these themes in mind, I had Lovart generate a holiday card (second image in post). From me to you, Merry Christmas & Happy Holidays Hope you enjoy the song 🧑‍🎄
