Overview
A high-performance sales analytics dashboard that visualizes mission-critical business metrics through real-time charts, filterable data grids, and scheduled export utilities. Designed to empower executive leadership and sales teams to make data-driven decisions without relying on static spreadsheets.
Problem
Sales operations depended on manually compiled spreadsheets that were updated weekly. Data was consistently delayed, fragmented across departments, and prone to human calculation errors. Management required a single source of truth delivering live revenue trends, regional performance, and conversion metrics in an intuitive interface.
My Role
As the Frontend Developer, I designed the modular component architecture, developed complex data visualization widgets, and optimized client-side rendering for large dataset manipulation. I collaborated closely with backend engineers to establish typed API contracts.
Technical Challenges & Solutions
Challenge: Client-Side Lag with Large Datasets
Rendering interactive charts containing 10,000+ data points caused significant browser thread blocking and frame drops on mid-tier hardware.
Solusi: Implemented intelligent data downsampling and aggregation algorithms based on the active viewport zoom level (hourly, daily, monthly). Combined useMemo optimizations with lazy loading for off-screen charts, reducing Time-to-Interactive (TTI) from 4.2s to under 1.4s.
Challenge: Complex Multi-Parameter Filter State
Managing combinations of date ranges, product categories, sales representatives, and geographical filters while preserving shareable URLs was prone to desynchronization.
Solusi: Built a type-safe URL state synchronization layer where all active filter configurations are reflected in URL query parameters. This enabled zero-reload navigation and effortless link sharing for cross-team reporting.
Result & Impact
- Slashed report generation and data lookup time from 30 minutes to instant real-time queries.
- 100% adoption rate across the 25-person sales and executive team within 2 weeks of rollout.
- Reduced financial reporting discrepancies by 80% through automated centralized data aggregation.
- Adopted as the primary dashboard for weekly executive strategic reviews.
