Guilherme Kulisky

At Ecowatt, I manage accounts receivable for a portfolio of 200+ clients, issue 500+ monthly invoices, and resolve billing discrepancies through systematic analysis across financial databases.

I also build financial KPI reporting, including a customer-service dashboard that centralizes outstanding balances and invoicing status while reducing manual lookups.

Previously at Hermit Crab, I defined campaign pricing strategies, ran A/B tests to identify profitable monetization systems, and presented data-driven recommendations to international teams. My forecasting work reduced the variance between forecast and actuals by up to 10%, strengthening pricing planning.

My experience also includes FP&A at Mercado Bitcoin and end-to-end finance at Wuzu, covering budgeting, cash flow, accounts payable, accounts receivable, payroll, reconciliations, and management reporting. I’m pursuing an MBA in Advanced Analytics and Business Optimization to deepen how I turn financial data into commercial decisions.
