Finance Dashboard

A real-time investment analytics dashboard aggregating multi-account portfolio data into one view — built for a fintech client whose users were previously piecing this together across three different broker exports.

The Challenge

Users were manually piecing together portfolio performance across three different broker exports in spreadsheets, with no single real-time view of allocation or risk.

The Approach

Built a purpose-built time-series data layer for sub-second historical queries, aggregated multi-account portfolio data into one live dashboard, added interactive allocation/performance/risk charts, and automated daily and monthly PDF/CSV reports by email.

What Was Built

  • Live portfolio valuation aggregated across multiple linked brokerage accounts
  • Interactive charts for allocation, performance, and risk exposure over custom date ranges
  • Automated daily and monthly PDF/CSV reports delivered by email
  • Sub-second query performance on historical data via a purpose-built time-series layer
