What am I all about?

I have over 20 years of experience working in different roles such as a developer, software engineer, architect, tech lead, engineering director, and tech CEO. In the last 14 years of my entrepreneurial journey, I have led two software development agencies and three startups. Currently, I am leading a team of software developers at React Geeks and Smart Geeks. I started Zooc in Feb 2019, an async video communication tool for teams. I have over 7 years of MERN stack experience and consulted renowned brands like Klarna, Siemens, Allianz, ImmoScout24, Zapp and many smaller startups.


What values I bring to the table?

Frontend Development

With over 15 years of frontend development experience, I can help you build rich UIs. I am deeply knowledgeable and experienced React.js and React Native developer.


Backend Development

I have extensive backend experience using Node.js, PHP, Python and ASP .NET. Although I am highly focused on frontend development, but am also a mircro-services and cloud computing enthusiast.


Software Engineering

Along with my bachelor degree in computer science with specialization in Software Engineering, I have also led several teams in building highly scalable software solutions.


Agile Methodology

I have worked in several agile teams and have not only learned agile methodologies from some books but have also experienced it first hand. Therefore I will be a very good fit to your team.



After several startups and a few dozen books around the topics of the lean startup and entrepreneurship, I can clearly see the value of iterating fast while building an MVP.



I am glad to be in the age of information who witnessed the evolution of web technologies which brought us information sharing and am proud now to be a part of the new web (blockchain), value sharing.
