CoderDojo is a movement orientated around
running free not-for-profit coding clubs and
regular sessions for young people.

At CoderDojo NOVA (“CoderNova”), young people learn how to code, develop websites, apps, programs, games and more. CoderNova is set up, run by and taught at by volunteers.  CoderNova makes development and learning to code a fun, sociable, and cool experience. CoderNova also puts a strong emphasis on open source and free software, and has a strong network of members and volunteers globally.

Thomas Debass (@debass) and Gelila Teshome (@GelilaAmare) co-founded CoderDojo Nova in 2013, driven by their desire to expose their three daughters the universal language of the future: coding. We’ve now grown to host biweekly workshops with dozens of youth, and reach over 200 families across the Northern Virginia area.


We are a program of the 501(c)3 non-profit NVCC Educational Foundation; and we are an independent chapter, unaffiliated with any other organizations such as CoderDojo DC or CoderDojo USA.



CoderNova has just one rule: “Above All: Be Cool”, bullying, lying, wasting people’s time and so on is uncool.


CoderNova is made possible by an awesome set of partners, parents, and mentors.  If you would like to join us, please email us at
