About Sasha Ivan

ENGLISH

Certified Public Accountant with 3+ years of multinational
experience at John Deere, combining financial operations
with process analysis and a modern technical stack.

Background:
- SOX Internal Audit — 4 group entities across Argentina
and Brazil, working alongside Deloitte external auditors.
End-to-end process analysis, root-cause investigation, gap identification and improvement proposals.
- Treasury — Multi-currency cash flow management (ARS/USD/EUR), variance analysis (forecast vs. actual), daily reconciliations across bank statements, SAP ERP and internal workbooks. Consolidated reporting to US headquarters under US GAAP.

Over the past three years I have intensively specialized in the technical stack now central to modern finance:
Python, SQL, advanced Power BI (DAX, Power Query), and the application of AI in financial analysis workflows.

What I help with:
→ Variance analysis and financial reporting (US GAAP/SOX)
→ Cross-system reconciliation and data validation
→ Power BI dashboards for finance, treasury and AR/AP
→ Process automation with Python (reconciliations,
reporting pipelines, data preparation)
→ Excel/Google Sheets optimization for large datasets
→ Financial process improvement and standardization

Available full-time, CET or EST hours.
Remote from Argentina.
