App development for iOS & Android, from Salzburg.

I do developing, consulting, testing, analysing. I work hourly or project based. Agencies are welcome as well.

Special offers for MVP, prototype development and start-ups.

I like the concept of KISS (Keep it simple & stupid). In app-development, the most important goal is to get a highly re-usable & maintainable code. The quality of code starts already when defining features and creating the design of an app. Applying KISS helps in each of those steps to improve quality and lower the cost at the same time. You can even speed up the development process in general. If something is high maintainable and re-usable, it is fast to make changes, implement new features as well as find bugs and fix them. Unfortunately, in the most projects I do not see any KISS. I see complicated processes and predicted deadlines are not met.

How to KISS

Aka How to keep it simple & stupid

For product owners and designers

Do not overload screens, make a new one if really necessary. Keep your app small and light. Rule of thumb, one screen for one atomic! use-case.

⬩ Use styles and layout guidelines from apple and google.

⬩ Do not invent new view elements, use what is there as a default element.

⬩ Reduce individual product owner and designer wishes. Users often don't want do see 'fancy stuff'. Users love KISS as well!

For developers

⬩ Do not over-engineer code, means like keep a clean, clear and simple! architecture, but do not invest too much in patterns and ideas for not so relevant things. You might change it soon anyway.

⬩ Force a clean code not by making complicated patterns that 'no one can break', but try to optimize the development, test and release process. Take time for code reviews.

⬩ Try not to optimize code by making more rules, try to optimize code by reducing complexity. It will pay back soon.

For all

Talk to each other! Bring your desginers and developers to feature meetings, as well as developers should explain product owners and designers their obsticles.
