Live Pulse
An operations panel that watches the world's pulse live: earthquakes, currency, crypto, weather and GitHub activity on one screen.
Problem, approach, evidence.
Problem
Showing scattered public data sources (earthquakes, currency, crypto, weather, GitHub) live on a single screen without server cost.
Approach
A server-side proxy and cache for each source; periodic refresh on the client, numbers that change as they stream, and live points on the map sized by magnitude. If a source doesn't respond, the last known data is shown silently.
Evidence
Lighthouse 98 and 1.0 s LCP on desktop; layout shift 0.001. On mobile it is 69 because of the map; I'm working on improving that area.
Five sources, five rhythms.
Staying live without hitting limits.
↑ The browser never touches the external API; the rate-limit problem is solved here.
Evidence in numbers.
Let's do the next one together.
