Sunju Hwang

I’m a data analyst with 6+ years in multinational corporate environments, focused on turning fragmented operational and financial data into clear, decision-ready insight. I build automated reporting pipelines and interactive dashboards that move teams from manual entry to strategic analysis.

At Organon, I owned the full data and reporting lifecycle using Power BI and Power Query, automating Sales, Gross-to-Net, and Returns workflows on top of SAP. I re-engineered manual reporting with Power Query, reducing manual workload by ~40% and shifting the team toward higher-level analysis and margin visibility.

I also supported end-to-end Order-to-Cash (O2C) and revenue assurance by monitoring AR/AP processes and collaborating with the Shared Service team to optimize invoice processing. In addition, I managed treasury and compliance activities, including monthly netting payments and Bank of Korea filings, while ensuring 100% compliance in tax reporting (VAT, Withholding Tax) and month-end close (accrual / open-PO reviews).

Previously, I acted as a cross-functional bridge between Finance, HR, and Procurement, led annual AR balance confirmations, and supported tax filings and internal audits with a consistently strong record of timely submissions. I’m comfortable with asynchronous, self-managed work in remote-first, distributed teams, and I’m based in Seoul (KST) with strong APAC and global overlap.
