Malte Schoppe – iOS Freelancer – iOS Freelance Developer from Germany

Malte Schoppe

iOS Freelancer from Berlin

Hi there!
I’m a mobile developer with experience building apps for the healthcare sector – work I’d like to keep doing, since it’s nice when the app you’re building matters.
This is backed by 8 years of iOS and 4+ years of Android development.
Have a look around to learn more about me, my projects and previous works.

TL;DR:

8 years of experience in iOS (UIKit & SwiftUI), 12+ apps released on the App Store
4+ years of Android development (Kotlin, Android Studio), 5+ apps released on the Play Store
Extensive knowledge of App Store & Play Store guidelines and the review process
Good understanding of mobile UI and best practices for the UX
Solid understanding in client-/ server architectures (HTTP, REST, WebSocket, XML & JSON)
Fluent in German & English

My Journey

I started programming within the Apple ecosystem in 2018 and have been pursuing it full time ever since.
I have been able to steadily expand my experience through publishing multiple apps on the AppStore, my time in an agency and in the past years as a freelancer.

After completing an apprenticeship as a mechatronics engineer in 2016, I taught myself programming while studying economics & IT in Passau, Bavaria. I liked the self-taught approach better than institutional learning at the university, so my priorities shifted quickly.

In 2021 I was able to elevate my skills to an intermediate/senior level at an agency in Berlin. The code quality continued to improve and working with new technologies and taking on responsibility and planning expanded my tech stack.
Following Scrum we accompanied and released several apps in a professional environment and project management.

Since 2022 I’ve been working as a freelancer, where healthcare projects have become the main focus, more of a happy coincidence than a plan, but one I gladly continue.

I’m still an iOS developer at heart, but Android development in Kotlin and preparing releases on the Play Store have become a solid part of my work.

Web Apps

These web apps run within a web view environment. While the basic setup is quick and straightforward, I list them individually because each one integrates native functionality.
Examples include QR code scanning, custom login and sharing logic, handling various API endpoints, and reading or writing cookie values. logic, sharing logic, different API endpoints or read and write of cookie values.
