Frontend developer working on a complex Bitcoin calculator for sats. Dealt with insanely complex mathematical formulas to help users track their Bitcoin goals.
SatsGoal needed a Bitcoin savings calculator that could handle precise calculations with satoshis, the smallest unit of Bitcoin. The math had to be exact since even tiny rounding errors could compound into significant amounts over time. They also needed to handle multiple currencies and Bitcoin price fluctuations in real-time.
Built a React-based calculator using BigNumber.js to handle precise decimal arithmetic without floating-point errors. Implemented real-time Bitcoin price fetching from multiple exchanges with fallback sources. Created visualizations showing how regular sat purchases compound over time. Added the ability to factor in different DCA strategies and compare results. All calculations are done client-side for privacy since users are entering financial goals.
React with TypeScript for type-safe calculations. BigNumber.js for precise decimal arithmetic. Multiple cryptocurrency API integrations with fallback logic. Chart.js for visualizing accumulation over time. All calculations run client-side for user privacy.
Tell me what you are building and when it needs to launch. I will come back with next steps.
