I build Playwright and TypeScript test automation for web apps and APIs, fast and stable enough to gate every release.

Based in Pune, India. Also growing into backend development with Java and Spring Boot.

Running the suite in Chromium, Firefox, WebKit and a phone

  1. [chromium] Visitor sees who owns the site on Home
  2. [firefox] Visitor switches theme and the choice sticks across reloads and pages
  3. [mobile-chrome] Visitor downloads the résumé as a PDF
  4. [webkit] every link to another website opens in a new tab, safely
  5. [chromium] a Case study tells its Problem, Approach and Outcome
  6. [mobile-chrome] a chosen theme applies before any deferred script runs, so there is no flash

Every test must pass

before a build is promoted to production.

Track record

  • 4.5+ years

    building Playwright and TypeScript automation for web apps and APIs.

  • 90 min

    for a full regression run, down from 4 hours after a Selenium-to-Playwright migration.

  • ~55% fewer

    flaky failures, from auto-waiting locators, reusable login state and fixes found in traces.

The site you're reading. No change reaches production until it passes the full Playwright suite in three browsers and on a phone, and the results are public.

Case study

Testing payment flows across microservices

A payment platform's authorisation, reconciliation, settlement and rollback steps ran across several services, and UI tests alone couldn't show where a transaction went wrong.

6 hours of manual reporting saved every sprint

  • TypeScript
  • API testing
  • AWS Lambda

Case study

Moving a legacy Selenium suite to Playwright

A large regression suite on a legacy Selenium framework took four hours to run and had frequent flaky failures, which made every red run slow to triage.

Regression runs: 4 hours → 1.5 hours
