A product tool that automated recurring PDF report creation from complex datasets. The work covered data shaping, frontend integration, visual reporting, and implementation of a repeatable export flow.
Overview
An internal reporting tool built to automate monthly client-facing PDF report creation for a Tokyo-based sales team. The project focused on turning a manual, engineer-dependent workflow into a structured UI flow for data selection, chart preview, and multi-page PDF export.
The sales team needed to prepare tailored reports for 20–30 clients each month, with each report spanning roughly 20–100 pages. The process depended on a team engineer manually working across a large internal financial database, PowerPoint, and Excel, which consumed significant time and introduced inconsistency risk.
The core challenge was to transform a manual, error-prone reporting process — tightly tied to raw SQL and spreadsheet-based preparation — into a repeatable, user-friendly workflow that could eventually be handled by non-technical team members.
