Meet WOVN's Developers

Jerome joined WOVN as a backend engineer. Keeping things performant was a big technical challenge, as they have hundreds of requests per second and billions of records in their database. To top it off, for a time it was just him and one other developer responsible for the backend.

Kseniya, a backend developer, was attracted to WOVN because it was a place where she could be herself, and wouldn’t be judged by her coloured hair, piercing, or tattoos. She found that flexibility extended to how they work, and people strived to create an emotionally supportive workplace too.
