Software developer & entrepreneur

I.am.addicted.to.coding. I once woke up from a solid 9 hour dream about me working on a new feature. I mean who does that?!

I love building products. I have managed the development of numerous web and mobile products. From a Fortune 500 corporation to a Y-Combinator startup, I have been an influential contributor in bringing products to market that improve and enliven everyday life.

To enrich my contribution to this process, I decided to learn how to code. I quickly fell in love with JavaScript and its libraries like Node.js and Angular.js.

I combine my international experience in business management and technical development to build product experiences that excite users. I recently launched my first AI product, I am passionate about fashion, veganism, community building & empowering women to pursue their dreams.

My peers describe me as bright, compassionate, determined to succeed. If you ever want to kick an idea around, feel free to do so!

Lets' build something!



Software developer

Every day i either write plain ol' javascript and i am using libraries like Node.js and Angular.js. to create exciting user experiences.

I have an exceptionally good eye for all things pixel and constantly update my designs based on user data and UI/UX best practices.

My previous management career definitely taught me a thing or two about process optimization, project management and being a leader. I manage engineers, plan (& execute on!) product road maps.

Kristina was great to work with. She always knew what needed to be done and how to do it. She led a small team to develop ground breaking software in a very short amount of time. She not only built the software from the ground up, but she was actively helping to develop other aspects of the business as well where we needed help. From culture to stats, she excelled at it all. She's fun to work with and super fast when it comes to picking up new skills. I would definitely work with her again.
