transparent performance tracking by crop and field.
Calculated production costs by crop and field (seeds, crop protection products,
•
fertilizers, fuel, land lease, depreciation, labor) with per-hectare breakdown.
Conducted plan-vs-actual analysis and identified key cost and yield variance
•
drivers.
Identified cost optimization opportunities and improved machinery and
•

Prepared analytical reports to support management decision-making on crop
•
structure and budgeting.
Achievements:
Achieved an 18% increase in EBITDA per hectare over the season by optimizing
•
costs and refining the crop mix.
Identified inefficient expenses totaling UAH 1.5 million and initiated cost
•
reduction measures, directly improving overall margin.
2018 – 2021 Deputy Director, Garant-Agro 4
Monitored operational KPIs (cost per hectare, yield, margin, machinery efficiency)
•
and provided regular performance analysis.
Supported budgeting and financial planning processes through data modeling,
•
forecasting, and variance analysis.
Improved data accuracy and consistency by streamlining data collection and
