We Are a Mobile App Studio

[design]   <prototype>   {develop}












We wireframe your idea first. We iterate until the app structure starts to make sense. Then we craft each screen into a beautiful pixel-perfect UI.


I am a strategical and practical thinker with 15+ yrs of experience in a wide range of technology roles. What I do is not just my job, it’s my life’s work and passion. Next up, I love my cat Snowwhite and hiking.

App prototypes help you get early user feedback before spending big money on building the wrong features.


Single feature and custom animation prototypes illustrate behavior better than static designs.

Co-Founder / Developer

I am a full stack developer and a quick thinker. I fell in love with programming since my first class back in college. I can't imagine life without stimulating challenges and my drums.

Thracecode are a highly collaborative and supportive team to work with. They offered guidance and expertise every step of the process from planning to wireframes to app launch. I found them extremely knowledgeable about mobile apps and app design. Would highly recommend.

I hired ThraceCode Inc. to design an application for my real estate business.  This was something I had dreamed about for some years but thought it would be next to impossible to achieve due to the complexity of the subject matter.  Katia was encouraging and supportive from the start and throughout the process.  I am so pleased with the how the App turned out and on the whole I am very impressed with the quality of the design and the high level of client service!

Katia and Sami from ThraceCode helped us to develop an app idea we had. They did everything they said they’d do, they were fast and delivered high quality work. Lots of attention to detail and insights which we appreciated. We would definitely work with them again.
