Malte in wenigen Worten

I have 10+ years of experience in developing and designing apps, web experiences and backends. Currently, I’m primarily focusing on native iOS-apps (Swift).

Latest achievement: I’ve built the entire technical infrastructure for investment FinTech Vantik together with one other developer.


Projekt- und Berufserfahrung

Januar 2019 - Juni 2019 | Berlin, Deutschland


Fitness First Germany GmbH

Freelance app and backend developer (​via anywhereinside UG)​

Together with another developer I’ve built the fitness video portal “My Fitness Video” for Fitness First. The project was set up with high scalability and security in mind and was built entirely with various components of Amazon Web Services (AWS). It consists of three main parts. Firstly the backend, where one of the bigger challenges was, to implement the whole payment and subscription process. Secondly the web app, a server-side rendered vue.js single page application, and thirdly the content and customer management system for administrators.

Heavily mobile-optimized web app, user login, user registration with multi-step onboarding flow, reset & change password, change email, video streaming, payment integration (Wirecard bank), subscription management, voucher codes, video recommendation based on user’s behavior, training programs, campaigns, analytics, cms for static pages

After having helped out Vantik as a freelancer end of 2017, I joined full-time in 2018 to build up the entire frontend stack and team.

Since Vantik is a banking product, highest priority in all layers of the stack was security and compliance with the German federal financial supervisory authority (BaFin).

The Boston Consulting Group

Freelance iOS swift developer ​ (v​ia functionalaesthetics GmbH​)

Together with a team of developers put together by functionalaesthetics, I was working on the iOS swift app (universal - iPhone & iPad) for Boston Consulting Group’s client, a Swiss insurance company. The app was designed to help families planning their everyday life. The main part of the app is an elaborate calendar, heavily optimized for easy user experience on both the iPad and iPhone. Furthermore, family members have profiles and can easily communicate through private messages.

Features​ ​(excerpt)
Calendar component, create & edit events, comment, animated onboarding, create & edit task lists, import calendars, sharing, push notifications, user registration & login, reset & change password, family setup, private messages, change app theme

Wein & Spirituosen

Wine in Black GmbH

iOS swift developer

Together with another app developer I’ve built the native iOS swift (universal - iPhone & iPad) app for Wine in Black, a wine e-commerce company. Due to the fact that Wine in Black is a curated shop with a limited, constantly changing assortment, the app stores all active products on the device and synchs with the server on startup so that all interactions with products such as browse, search or filter are instant and do not require a network connection.
Besides working on the iOS app, another part of the job was building a new REST API. This was necessary because the existing shop system was being replaced during the project.

Push notifications, campaigns, product detail page, cart, checkout, order history, profile, filters & search, custom transitions, store country switching, user registration & login

Technologies used
App​: Swift, UIKit, iAd, Core Image, Fabric, Fastlane, OneSignal, Crashlytics, Analytics
Backend​: PHP, Spryker Commerce OS, MySQL, Integration tests

Soziale Netzwerke

universeiscool UG

iOS swift developer

For universeiscool, I built the social image sharing app FOYER. It enables the user to combine text and photos into a story and a layout algorithm takes care that stories look unique and good on any device. An integrated image editor provides an easy way to get the most out of the pictures and social features such as share, like and comment make sure that stories get the attention they deserve. The social feed channelizes the stories created or shared by followed users and the discover section in the app exposes stories of users from outside the user’s network.

Login, registration, animated onboarding flow, story page, story editor, image editor and picker, social feed, like, share, comment story, discover section (stories & users), profile, push notifications, web app for cross-platform use

Technologies used
App​: Swift, UIKit, Core Image, Core Graphics, Core Animation, Alamofire, MVC, Unit tests
Web​: Angular.js, Image proxy
Backend​: Node.js, REST, Koa.js, AWS S3, AWS Lambda, AWS Simple Notification Service, AWS Simple Email Service, Neo4j Graph Database, Integration tests
