Crypto Portfolio Chart Integration

@gigadevca

Hello, I’m Asad Jahangir, Founder & CEO of The Coding Company, a Silicon Valley–based software development firm. We can build this as a clean, responsive crypto portfolio widget for your website that shows exactly what matters: what you paid, current value, and profit/loss, with live price updates. To keep it simple and maintainable, we’d recommend a React-based front-end module using Chart.js. The widget would connect to a market API such as CoinGecko for live prices and use your holdings data (or a simple editable config/admin input) to calculate: • Total portfolio value over time • Allocation by coin • Profit/loss per asset and overall • 24h / 7d / 30d change Since you mentioned Coinbase and Tangem, we can either: 1. Start with a manual holdings editor where you update quantities and cost basis yourself, or 2. Explore API-based syncing later if needed. We’ll make sure it works smoothly on iPhone Safari, supports dark/light mode, updates automatically without page refresh, and is easy to embed into your current site. Best regards, Asad Jahangir Founder & CEO The Coding Company LLC

Hi there - your goal to deliver a clean, interactive crypto holdings chart that updates live, is fully responsive, and iOS-friendly is exactly what I deliver. This maps directly to my experience in data visualization and frontend integration for live price feeds. I'm Iosif Peterfi, 15+ years delivering reliable web experiences for fintech and crypto clients, with a practical, business-first mindset. I'll deliver a self-contained front-end chart module that consumes your wallet balances JSON, merges it with live prices through a small, swap-friendly data layer, and renders a time-series portfolio value line, a current allocation donut, and 24 h/7 d/30 d change badges. It will be responsive, tested on iOS Safari, support pinch-zoom, tap-to-view, and dark/light theme switching, and update without a full page refresh. You'll get an embed snippet and a step-by-step integration guide, plus a brief README showing how to point to a different API later. The solution will stay lightweight, accessible, and drop-in ready, with risk mitigations like debounced updates and a stable feed wrapper to prevent glitches on rotation or theme change. Last month I helped a crypto fintech deploy a mobile-friendly portfolio chart that merged wallet balances with live prices; we cut update latency to under a second and boosted portfolio page engagement by 40%. Let's chat - I can walk you through my approach in 15 minutes. Portfolio: https://www.freelancer.com/u/iosifpeterfi

Hello, I hope you're doing well. I understand you're looking for an interactive portfolio chart to display your cryptocurrency holdings on your website. This is crucial for providing transparency on your investments, especially since you'll have most of your audience viewing it on iPhones. With my experience in API integration and data visualization, I can create a fully responsive chart that supports smooth pinch-zoom and tap-to-view functionality. I’ll ensure it pulls live price updates from a reliable crypto market API, while keeping the logic flexible enough for future changes. The deliverables will include a time-series line chart for portfolio value, an allocation pie chart, and easy-to-read percentage changes. To ensure seamless integration, I will provide an embed snippet, a detailed setup guide, and a README on how to switch API feeds. I'd like to have a chat with you at least so I can demonstrate my abilities and prove that I'm the best fit for this project. Warm regards, Natan.

Hello, Will the real-time data feed require integration with both Coinbase and Tangem wallets to accurately display your cryptocurrency holdings? Do you have specific security requirements for handling wallet balance data and live price updates securely within the chart component? Additionally, will the chart need to support multiple cryptocurrencies or only specific ones from your portfolio? I take full ownership of ensuring a stable and production-grade delivery of the interactive portfolio chart. Communication will be direct and efficient throughout the project. Let’s align on the details and move forward. Best regards, Vitalii
