Hi, I'm Steffen. I build apps and SaaS on my own in Berlin.

🇪🇸 Carpincho: Spanish for the moments you actually land in. Every word in three accents. $794 last month.
💪 Kolibi: food + bodyweight training in one app. It's how I track my pull-up goal.
🤖 Erdi 2.0: a 3-minute morning briefing for founders. Waitlist open.
🗂️ Orivela: say it, type it or snap it, and it gets filed. Ask in plain language and it comes back.
🥗 GetaBite: vegan and vegetarian spots, with the dishes they actually serve.
🧱 Find My Stack: a few questions about your app idea, one honest recommendation on how to build it.
👩‍💻 erdibuilds: pick verified developers who have built apps like yours. Waitlist.

Building something too? Tell me what, I'll cheer you on.
