I'm a co-founder and business operations leader with 7 years of experience building company systems from scratch — sales pipelines, hiring processes, client workflows, quality control, financial planning, and cross-functional coordination. After years of running operations at an international scale, I've freed up capacity and I'm now bringing that experience to select clients who need a senior operator in their corner. 🚀 Where I add the most value: - Diagnosing what's actually blocking your growth and fixing it at the root - Building SOPs, workflows, and accountability structures your team will actually follow - Setting up KPI tracking and reporting so you always know what's happening - Turning founder vision into clear execution plans with defined owners and deadlines - Bridging the gap between strategy and day-to-day operations - Managing cross-functional teams, contractors, and vendors end-to-end 💻 My background: - 7 years co-founding and operating an international SaaS agency (10-person team, 40% net margin, 350+ projects delivered) - Built and documented SOPs for every core business function: sales, client onboarding, project delivery, HR, and finance - Worked hands-on with 20+ startups on go-to-market strategy, sales process, and operational setup - Supported clients in raising $175M+ in investment capital - Previously built and led sales operations at Creatio — a global CRM platform 🛠 Tools I work with: HubSpot · ClickUp · Notion · Asana · Google Workspace · Slack · 🎯 Best fit if you are: - A founder who's wearing too many hats and needs someone to take operations off your plate - A growing team that's outpaced its current systems and processes - A startup that needs operational infrastructure built before scaling Native Ukrainian speaker. Fluent in English. Based in Argentina — perfectly positioned between US and European time zones. 💬 If you need a senior operator who's been in the trenches and knows how to build systems that scale — let's talk.
