About Irina

15+ years in finance leadership. Deloitte audit roots. Ran the CFO office for a $20bn PE fund. Now I help growth-stage and mid-market companies fix what's not working in their finance operations — and I actually implement it, not just advise.
I've consolidated 70+ entities onto one platform, cut audit fees by 20%, reduced consolidation timelines from 3 months to 2 weeks, and saved $1M+ annually through process redesign. Currently consulting for a $400M+ fintech on revenue accounting and treasury optimization.

Luxembourg-based, remote across Europe
I'm at my best when the finance function needs both a strategic brain and someone willing to roll up their sleeves. If that sounds like what you need — let's talk.
