Hi, I'm Anselm Kessler, a mobile app developer with 5 years of experience building Android and iOS apps with Flutter, React Native, and native tools. I've worked across many industries, so I can match the right technology to your project instead of forcing one stack onto it.
I work in English, Portuguese, Spanish, French, and German, so you can brief me in your own language. Expect clear timelines, regular updates, and full source code.
Message me with your idea and I'll tell you honestly what it will take to build.
FAQ
Which platforms do you build for?
Android, iOS, or both. I use Flutter or React Native for one codebase on both platforms, and native Swift or Kotlin when the project needs it.
Can you build my app from scratch if I only have an idea?
Yes. Send me a short description, even rough notes or sketches. I'll suggest the features, tech, and a realistic timeline before you commit.
Do you include design?
Yes. I build clean, easy-to-use screens. If you already have Figma or other designs, I'll follow them closely.
Can you add logins, payments, or a backend?
Yes. I set up Firebase, REST APIs, user accounts, push notifications, and payment gateways such as Stripe.
Will I get the source code?
Yes. You receive the full source code and own it. Higher packages can include setup notes so another developer can continue the work.
Will you help publish the app?
Yes. I can guide you through submitting to Google Play and the App Store. You'll need your own developer accounts.
What languages do you work in?
English, Portuguese, Spanish, French, and German. Feel free to message me in whichever you prefer.
