Ewald Horn
Remote Flutter Consultant. Dart and Flutter on Android and iOS.
Prototype to MVP and Production.
Cape Town Area, South Africa
Summary
Working 100% remotely, as a contract developer, I deliver solutions
using Flutter with Dart on Android, iOS, web and server.
In the past, I've worked in Kotlin, Python, C#, Xamarin, F#,
JavaScript (NodeJS), NativeScript, Java (Android, ME, SE, EE),
Scala, Swift, C, C++, PHP, HTML5, Pascal, Delphi, Objective-C and
some time ago, Cobol.
My remote work is done via technologies like Slack, Skype, Zoom
and Trello.
I'm very open to working with startups, even those that are in the
exploratory phase and in need of an app to go for a funding round.
Depending on your product, I might be tempted to work for partial
equity, up to 15% of my total fee.
I'm busy studying more machine learning, data analysis and data
science, using tools like R, RStudio, Pandas and TensorFlow.
Some things I've worked on:
- Payments systems like Postilion
- Social Media apps like Wyzetalk
- Video and media apps like Doozie and Over
- Mobile Games like Juicy Kaboom
- All kinds of fintech things like pension fund and employee benefits
managements systems
- An assortment of mobile apps for Android and iOS like HomeKick
I've been a Java developer, Mobile developer, Android developer,
Applications developer, Software Engineer, Support Technician,
Trainer, failed comic and rather bad barista. Through it all, one thing
remained constant - delivering results.

If you are here because of the Code.org volunteer program, I
am available to visit your school and assist your students with
programming challenges and assignments, completely at my own
expense, depending on my schedule.
Experience
NoFuss Solutions
For Hire - Remote Contract Mobile Developer
January 2005 - Present
International
I primarily deliver discreet solutions in the Android and iOS mobile space using
Java, Kotlin, Flutter, Dart and Xamarin.

focus using technologies like Dart, Vue.js, JavaScript, HTML and CSS.
I am available to assist you with prototyping your application for initial funding
rounds as well as delivering production-level mobile applications.
Over
Android Developer
January 2018 - June 2018 (6 months)
Cape Town Area, South Africa
Working on the Over Android application using fun technologies like Kotlin and
OpenGL ES.
Estalea
Senior Mobile Engineer
July 2015 - December 2017 (2 years 6 months)
Durbanville, South Africa
Working with C# (Xamarin), Scala, Android (Java), OpenGL, JavaScript,
HTML5, CSS, Ractive.js and a touch of Swift on iOS.
Check out www.estalea.com and www.doozie.com for more about the
company.
On Doozie, I worked as the lead Android developer, building a native video
capture and augmentation application. By using low-level API's, I was able to
Page 2 of 7
capture video live and apply different filters and effects. An added bonus is the
ability to pause and resume recording, from Android 4.4 and up.
One project was built on Xamarin technology, with a shared common layer
between the iOS and Android clients. I was mainly involved with the Xamarin
Android effort.
Most of the backend API's are written in Scala and I had to write many
services required for the mobile clients as well. The admin console is a Scala
Play application, relying heavily on Ractive.js for the templating.
At Estalea, each team member picks up whatever task needs doing. As
an example, I ended up porting comments from MySQL to DynamoDB, an
exercise that required Java and Scala skills, along with a fair bit of SQL.
I also built some tools we used for data manipulation in a technology called
NW.js, which is a NodeJS and embedded Chrome setup. It's ideal for building
HTML5 interfaces that need more access rights to the machine than what a
traditional web application would have.
As a partially distributed and remote team, we use Slack, Skype, Trello, and
Git to keep track of our work.
