Investment Dashboard With Daily Returns

I’m building a client-facing dashboard that lets investors track their portfolio growth day by day. The page must automatically display each day’s return in both percentage and absolute currency, then visualise the cumulative progress with easy-to-read bar charts.

Core functions
• Securely pull or accept uploaded data (CSV, Google Sheets, or a lightweight database you recommend) and refresh the figures once daily.
• Render an interactive bar chart that updates in place, allowing clients to hover for exact values and filter by date range.
• Show today’s change prominently, then list historical returns underneath so users can trace the growth over time.
• Clean, mobile-responsive layout so the dashboard looks just as good on a phone as on a desktop.

I’d like to see a concise yet detailed project proposal in your bid: the tech stack you plan to use (React, Vue, Django, Laravel, etc.), how you’ll handle data security, and a brief milestone schedule from setup to final hand-off. Links to any similar dashboards you’ve built will help me choose quickly.

The finished deliverable is a polished, self-hosted webpage (or small web app) with source code and deployment instructions, ready for my team to point at live data and share with clients.
