Building teams
that ship reliably.

Venelin Velev - Software Development Team Lead in Sofia, Bulgaria. Engineering leader with 9+ years of hands-on experience, currently leading a cross-functional team of six developers and QAs. I combine technical depth with delivery ownership - I plan the sprints, review the code, carry the pager - and still ship production code.

Open to Engineering Manager roles - Sofia or remote.
