Performance Optimization

A fast app keeps users happy and gets more of them to sign up or buy. I look at the whole picture: page loads, database queries, caching, AI features, and the backend. You end up with an app that's quick and can handle growth.

Real-World Expertise

  • I kept the WidgIq widget tiny. It's a single JS file of about 10 to 15 KB, with no npm install, no build step, and no framework, so it doesn't slow down the site it sits on.
  • Replies stream in token by token, so visitors see an answer start right away instead of waiting for the whole thing. Standard mode is quick for simple questions, while Smart and Advanced spend more time when accuracy matters more.
  • Widget settings are cached with Next.js and revalidateTag, so a color or font change shows up on the live site instantly, with no redeploy.
  • Knowledge base updates are targeted. Owners can refresh a single page instead of re-crawling everything, and only pay credits for what's new or changed. Search runs on pgvector, so lookups stay fast.
  • Redis rate limiting and Inngest background jobs keep things stable as traffic grows.
