The SRS Classes

Overview

The SRS Classes is an educational web application for students preparing for competitive exams. I built and shipped it as a solo freelance contractor — from first feature to live deployment — and it now serves 1,500+ daily active users with stable, cross-device performance.

The challenge

Exam aspirants browse on whatever device they have, often on slow connections — and a sluggish learning platform quietly costs engagement. The site needed to feel fast and stay reliable as daily traffic climbed into the thousands, all delivered on a freelance timeline by one developer.

Performance work

The headline result was a ~30% reduction in page load times. That came from a deliberate set of optimisations rather than one trick:

$ ./optimise --report

  page load time   ████████████░░░░░░░░   -30%
  SSR first paint  ██████████████████░░   fast
  daily users      ████████████████████   1,500+
  cross-device     ██████████████████░░   stable

Owning the lifecycle

As the sole contractor, I owned every stage: feature development, cloud deployment, monitoring, and post-launch maintenance. There was no team to hand off to — which meant decisions had to be sound the first time, and the codebase had to stay maintainable for the person who'd return to it: me.

Outcome
