Performance & Analyticsby SoftwareCrafting

Service Overview

We make web applications fast in the way that actually counts, which is field data from real users on real devices and networks, not a lab score from a developer laptop on office wifi. Work starts with measurement: Core Web Vitals from your actual traffic, segmented by device class, connection, and geography, so you know whether your problem is Largest Contentful Paint on mid range Android, layout shift from late loading images, or interaction latency from too much JavaScript on the main thread. Then we fix in order of impact, usually image and font strategy, bundle size and code splitting, third party script governance, caching and rendering strategy, and server response time. We pair that with analytics that answer product questions rather than producing vanity dashboards, including conversion funnels, event tracking with a schema your team agrees on, and privacy compliant setup that does not depend on cookie consent to be useful.
