Bio

Passionated about computers, Karen started coding when he was only 13 years old, and during high school, he was already successfully participating in competitive programming. He worked, first, at CodeSignal as a content engineer, where he solved many algorithmic problems and improved the processes of automatic grading and task generations. Now at Krisp, as a C++ software developer on the software development kit (SDK) team, Karen improved his knowledge in software development and deep learning.
