From skincare and haircare to fitness, nutrition, and personal finance — Drop The Routine empowers creators across every niche to help their audiences follow through.

I built Didja — a minimalist habit tracking app — to help me achieve my longterm goals by holding me accountable to daily action. It lets users define their goals, create daily or weekly routines that support them, and stay accountable through simple, structured tracking that promotes action. I designed it to be clean, distraction-free, and genuinely enjoyable to use. I finished it a few months ago, but I still use it everyday!

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

https://suno.com/s/4uljwsdGoTEIMJ8U For this New Year Suno AI song, I was inspired by the New York ball drop (reference image (https://image.newyork.co.uk/wp-content/uploads/2023/10/New-Years-Eve-in-New-York.jpg)). Hope you have a Happy New Year 2026! Card created in Lovart.

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 🧑🎄
