Malte in a few words

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.




Digital Agency and IT company

Freelance iOS Swift Developer

Berlin, Deutschland

July 2019 - November 2019

CHAINWISE Group hired me to kick-start their product "Wombat" for iOS. For this greenfield project, I did both the architecture and the implementation of the beta version and later hired another developer who eventually took the project over.

The app is the first EOS wallet built for everyday use and simplifies the creation of EOS accounts through a three-step onboarding process. It automatically encrypts and stores the private key in the cloud and makes sending/receiving EOS tokens a breeze. One of the core features of the app is the DAPP Browser that acts as a proxy between DAPP and the EOS account and provides a streamlined user-interface to sign transactions.

Login, EOS account creation, Send/Receive EOS tokens, sign transactions, SDK for third-party apps, Manage EOS keys, Unlock private key, Prime subscription, EOS resources overview

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

München, Deutschland

May 2017 - January 2018

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.

Wine in Black GmbH

Wine & spirits

iOS swift developer

Berlin, Deutschland

December 2015 - May 2017

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

universeiscool UG

Social Networks

iOS swift developer

Berlin, Deutschland

January 2015 - December 2015

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.
