Syncing both worlds manually is painful.

Spring Data JDBC supports both approaches, and IntelliJ IDEA generates DB schema from entities and entities from schema 🔄
Two-way productivity unlocked!

I'm open to work!
People know me for my skills in Android, Kotlin, Compose, Gradle, Android Automotive, or for my hunger in eating issues for breakfast. You might also know me from my talks at @droidcon.bsky.social!
I'm proud to have worked with the best at @snappmobile.bsky.social. New adventures!

Yes it makes sense, for Desktop I am still using the Apple Mail, but I never liked it, maybe I will test the Thunderbird client.

Casey Muratori pretty much sums up how I feel about LLMs for coding:

"The AI will always be useless for me. I physically can't get what I want from programming when AI is involved, because what it is doing is robbing me of the experience that I wanted to have and the knowledge that I wanted to get"
