hi, i'm oskar (osrott61)

android builder, open-source enthusiast, and homelab enjoyer based in mannheim. i'm into cars, bikes, football, homelabbing, and programming.

• currently working on lineageos 23.0 for various devices
• building extremerom-kebab for oneui 8 (private)
• passionate about open-source android development
• growing and maintaining my own homelab since january 2025

outside of tech, i'm heavily interested in cars and bikes, especially older vehicles. some of my favorite cars include the mercedes w123 and w126, audi a8 d2 and audi 80, and bmws like the e38 and e30. i also own a lowered and modified opel astra g, and enjoy learning about mechanics and tuning.

i'm also into bikes because my dad used to own a motorcycle repair shop and was active in racing until 2014. growing up around that environment got me into motorsports early on.

besides all that, i'm the stage technician at my school, handling lighting and tech for performances and events (sometimes until way too late — record was 3am).
