Iryna Sinkevich

I am the Head of Finance & Operations at YSecurity, supporting both YSecurity and CyberBase.ai — two technology companies founded in Silicon Valley and focused on cybersecurity innovation and AI-powered developer tools. I manage all core financial and operational processes across both companies, including budgeting, reporting, vendor management, compliance, accounting systems, payroll, contracts, and day-to-day operations. My work ensures that our product and engineering teams can move fast, innovate, and scale without operational blockers. Areas of responsibility: • Financial strategy & budget planning • Operational systems & internal processes • Contractor and vendor coordination • Payroll, invoicing, compliance • Financial analytics for founders • Supporting hiring and team growth • Ensuring smooth operations for both product lines I enjoy building strong operational foundations for fast-growing technology companies and helping founders scale efficiently.
