Frequently asked questions

What type of projects do you take on?

I specialize in designing for both mobile and desktop platforms, focusing on websites and applications. Additionally, I create marketing materials such as mockups, business presentations, and ad creatives. My goal is to deliver visually compelling and user-friendly designs that enhance your brand and engage your audience.

What is your hourly rate?

I only charge hourly for my ongoing projects that need work on the regular. One-time projects are charged upfront to keep it transparent and clean! My hourly rate is $70.

What time-zone do you work in?

I work Central European Time, but I'm always ready to help out in emergencies, no matter the hour.

What is the typical timeline for a project?

Depends on the scope of the project, really. Some projects take less than a week. Some take months. The best way to find out is to get on a quick call with me, and discuss it. No strings attached!

How do you charge for projects ?

I quote a price upfront--so that you know exactly what you're paying and for what, and there are no surprises later. The exact cost of your project depends on the scope and requirements!

What does your design process look like?

I take a problem-forward approach. Whether we're iterating on an existing product or building a new one from scratch, how to solve the user's problem in the simplest way possible is my first concern.

Send me an email to understand my process in depth!

What metrics do you use to measure success?

The best metrics are customer adoption, happiness, task success, and engagement. There are a number of frameworks such as the System Usability Scale that help us understand product performance and I'm happy to help with that.

What if I need help after the project is complete?

I always make sure to help out my clients one month after the project ends, for free. For any help post that, we can work out an ongoing arrangement!
