The Lab
Interactive experiments — each module is a small, shippable engineering slice. Live code, typed from boundary to render, documented alongside.
Who Am I?
Real-time visitor intelligence — IP, location, browser, device, fingerprint tiers with granular consent.
Server Metrics
SSE-streamed server telemetry — CPU, memory, RPS, error rate with 60-second sparklines and exponential-backoff reconnect.
Weather Dashboard
Open-Meteo powered — current conditions, hourly and 7-day forecasts, sunrise/sunset arc, EU AQI bands.
