Sheet 4 of 5Experience

Four years at Cargill ran through three roles, each with its own centre of gravity: technical, financial, and people work. Rather than flatten them into one line, each is drawn as its own section.

Sections

Three roles  ·  one function

Cargill, July 2021 to August 2025, 4 years 2 months, Uberlândia, Brazil, hybrid. Three roles inside the same corporate tax function. Each section below cuts one of them, most recent first.

Section A – A  ·  Data analysis and automation

Data Process Lead

Latest of three
Automation and reporting

Embedded technical work inside a Fortune 500 finance operation. Identified workflow bottlenecks, measured their cost, and built automation pipelines that ran at team scale.

  1. Built automation pipelines for tax reconciliation between fiscal books and accounting ledgers using Python, SQL and KNIME, replacing manual spreadsheet checks with scheduled runs that surfaced only the exceptions worth a person's time. Adopted across multiple teams.
  2. Turned one-off analyses into reusable tooling for balance validation, tax reporting and financial auditing, parameterised so other analysts could run it against their own entities without touching the logic.
  3. Created Power BI dashboards on top of the reconciled data, surfacing financial accuracy metrics and period-over-period movement to support executive decision-making.
  4. Early adopter of AI for process automation, introducing AI-assisted workflows before it became standard practice in the organisation.
  5. Documented each pipeline with a runbook and a named owner, so nothing built depended on one person staying in the seat.

Section B – B  ·  Finance & commodities

Commodities Tax Analyst

Second of three
Reconciliation and audit

Core financial operations inside one of the world's largest agribusiness companies. Worked where tax law, accounting standards and regulatory reporting intersect, at enterprise scale, with real consequences for accuracy.

  1. Managed tax reconciliation between fiscal books and accounting ledgers across complex multi-entity corporate structures, carrying every difference to root cause before close.
  2. Owned the recurring close cadence: prepared and reviewed reconciling items, documented adjustments against their supporting evidence, and left an audit trail a reviewer could follow unaided.
  3. Supported RTR (Record to Report) processes in collaboration with international finance teams across multiple regions, working to their calendars and handing off with the context the next time zone needed.
  4. Built and maintained financial auditing frameworks for balance validation and corporate tax reporting, standardising the checks so accuracy did not depend on who ran the cycle.
  5. Drove financial accuracy and efficiency improvements across reporting cycles using structured analytical pipelines.

Section C – C  ·  Finance & people

Junior Tax Analyst

First of three
Training and client work

The client-facing and people side of the first role at Cargill. In a company of that scale, managing relationships and running training programs is its own full skill set, not a side task.

  1. Onboarding ownership. Designed and delivered onboarding training for new team members end to end, from curriculum and materials through shadowing and ramp checkpoints. No supervision required.
  2. Bilingual training programs. Led external initiatives spreading bilingual EN/PT training for high-performance professionals across Cargill's ecosystem, running sessions in both languages and writing materials that stayed useful after the session ended.
  3. Direct client negotiation. Managed expectations, handled escalations, and built trust across multiple client and stakeholder groups in a complex B2B environment, keeping people informed while a fix was still in progress.
  4. International team coordination. Bridged communication between Brazil operations and global finance units on RTR processes, translating local practice into terms a global team could act on.
  5. Process-to-people translation. Converted technical financial workflows into structured, accessible training materials for cross-functional audiences with no tax background.
