Malte in wenigen Worten

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

| 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.
Features 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. Vantik is an investment-based retirement savings product (private pension). 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).
Stack 1. Customer web app BaFin compliant multi-step user registration, deposit & withdraw money, payment history, multi-factor authentication, change linked bank account, tax exemption settings, account settings, account balance, customer login, reset & change password 2. Admin web app User management, payment management, voucher codes 3. Visitor website Static website generator fed by a headless CMS (Prismic) and hosted on AWS S3 4. App (iOS) Customer login, account balance, deposit & withdraw, account settings
Freelance iOS swift developer (via 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 smile.direct, 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.
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.
Features Push notifications, campaigns, product detail page, cart, checkout, order history, profile, filters & search, custom transitions, store country switching, user registration & login
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.
Features 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
