I’m Pirasanth - but call me PJ.

About me section

I'm a QA automation lead. I like tests that fail for good reasons.


At CoinCover I grew the QA team from 1 to 3 engineers, took E2E coverage from 0% to 90%+ and moved releases from monthly to weekly. Nothing glamorous: good tests, sensible quality gates, and a lot of patience with flaky ones.

…and lately I've been building AI tools that diagnose failing tests, and a dashboard that helps decide whether a release should go out.

Portfolio section

I lead QA and test automation. Every project here starts from a testing problem I had to solve. Open one to see how I approached it and what it proves.

AI writes tests quickly. Who checks the AI?

Test emails with Cypress.io

We will be discussing a topic that has been talked about when it comes to E2E testing. 
It's vital to cover complete E2E testing, even if the user receives an email confirmation.
