Ivana is a great engineer. I was fortunate enough to be able to work with her on one of her projects. I was blown away by not just the volume of work but the level at which it was executed at. I've seen teams with decent funding not achieve the level of work she did on her own. She doesn't stop there. It's truly a pleasure to work with her. She is very collaborative and incredibly receptive of all ideas. Ivana always manages to keep the goal in focus and push on to the next milestone. Lastly, she rounds out her skills very nicely by being able to push pixels. Ivana not only takes great care to make things work fluidly but at the same time, she ensures they look great too. 👌

I've been working with Ivana extensively for over a year now, on both the Counterparty and Symbiont teams, and have been very happy with the quality of her work. On top of being intelligent and able to figure things out on the fly, she's a very hard and diligent worker. The breadth of her skillset allows her to be very flexible, and to be able to adapt herself to most any situation she's put in. She's done a very good job on everything from marketing to software development for us. Highly satisfied.

Over the past year, I've worked with Ivana on a number of projects relating to digital currency, open-source software and non-profit organization management. She has proved herself diligent in the fulfillment of her duties and an all-around hard worker. She is a trustworthy and reliable employee.

Ivana was very professional to work with. Her large scope of skills made her a valuable team member. I urge any future employer to carefully consider Ivana who is a hard-working and top-performing Frontend Developer and General Manager.

Ivana's work as General Manager of the Counterparty Foundation is superb. Her breadth of skills as a designer, frontend developer, copywriter, and social media lead is very rare to find. I cannot recommend her highly enough.

Jurica Smircic

CEO, Rathmann


Ivana is a dedicated, ambitious and result driven professional who always goes above and beyond of what is asked of her. She is able to quickly pick up new skills, learn new frameworks and languages and continually deliver results. Her creative thinking, expertise, positive can-do attitude and drive made her an absolute pleasure to work with. I highly recommend her.

Ivana is very committed to what she does and takes work very seriously. She is a quick and creative thinker who knows how to ask the right question, open-minded and communicative, with high IT skills. As a team member, she is a very cooperative employee and a person you can rely on. Her main tasks (besides mentoring) were to explore new technologies and develop business solutions based on the Microsoft technology. Dealing with the issues of new technology tools is just one of many challenges for her.

Ivana is professional and highly skilled IT professional. She possesses superb skills and is an amazing person to work with. She is a leader in her field. I highly recommend her.

Ivana and I met through a mutual business connection about a year ago. Since then I have learned of Ivana's passion for social media and attention to detail. I highly recommend Ivana to anyone planning their social media strategy and wants to work with a professional who delivers 5 star service.
