What I'm looking for

I’m looking for a role where I can own full-cycle bookkeeping and month-end close accuracy, while using analytics and dashboards to improve reporting timeliness. I want a fast-paced team that values data quality, process improvements, and clear stakeholder communication.

I’m a detail-oriented Bookkeeper with 4+ years of experience managing full-cycle bookkeeping, including AP/AR, reconciliations, and month-end close. I’m known for improving processes, ensuring data accuracy, and supporting financial reporting in fast-paced environments.

In my accounting roles, I handle General Ledger (GL), journal entries, cash & bank reconciliation, tax compliance, and audit support. I’ve managed full-cycle bookkeeping for 7+ clients, maintaining accurate financial records and strengthening internal controls through streamlined AP/AR workflows.

I also bring practical analytics skills to the finance workflow—data cleaning, validation, and business intelligence. I built forecasting and classification models (time series and churn prediction) using Python, focusing on feature engineering, hyperparameter tuning, and actionable insights.

Now, I’m excited to combine reliable bookkeeping and reporting with analytics and dashboarding (Power BI/Tableau/Excel) so stakeholders can make faster, better decisions. I take pride in translating complex results into clear stories and continuously improving data readiness, reconciliation accuracy, and reporting timeliness.
