01 · About
Lead - Software Quality Engineering at VitalHub
Innovations Lab
Starting as an intern in 2019, I quickly learned the bugs that mattered most weren't in tickets. They lived in requirement gaps, flaky pipelines and the quiet places where teams stopped asking "but what if?"
Seven years on, I lead the test automation efforts at VitalHub Innovations Lab, building reusable frameworks across Selenide, Playwright, Cypress and REST Assured, and designing AWS native performance harnesses running hundreds of concurrent browser sessions on Fargate.
But the work I’m most proud of isn’t the code. It’s shortening release cycles, mentoring junior engineers into confident automation owners, and embedding accessibility checks directly into pipelines making quality impossible to bypass.
Looking ahead, I'm exploring how AI can eliminate repetitive work and raise the bar for quality. To me, quality isn't a phase, it's a posture.

PVT Docker Framework
Performance Verification Testing on AWS Fargate
Problem
Performance load testing was capped by local machine resources and couldn't
realistically simulate the concurrent browser sessions of video conferencing platform seen in production
both
patient and clinician sides of a live video call simultaneously.
Solution
Contributed to an AWS native framework that packages Playwright scripts into
Docker images, spawning hundreds of ECS Fargate tasks across 7 AWS regions in parallel. PowerShell scripts
drive task definition generation and service orchestration, with run configs and screenshots aggregated
centrally in S3.

Selenide BDD Automation Framework
End to end test suite for a patient flow healthcare management system
Problem
A complex, multi tenant healthcare platform with clinical workflows spanning
scheduling, referrals, assessments, and encounters. And no automated regression safety net. Every release
was a manual testing bottleneck.
Solution
Built a UI BDD framework using Maven, Selenide, Cucumber, and TestNG
with a Page Object Model, Allure reporting and a Dockerised Selenium Grid for parallel cross browser
execution
across multiple client environments.

Rest Assured API Regression Suite
Automated contract validation across microservices
Problem
REST API contracts were verified manually through shared Postman collections.
Endpoint changes broke integrations silently, with failures surfacing days later during E2E UI testing rather than at the source.
Solution
Built a Rest Assured framework in Java with TestNG, covering auth flows, schema
validation, and negative path scenarios. Environment agnostic config let the same suite run locally and in CI without modification.

K6 Performance Testing Framework
Dual layer load testing — protocol and real browser
Problem
Protocol level load tests miss what users actually feel. Client side
regressions in metrics like LCP and CLS never surface in pure HTTP load tests, so teams discover them
only after release.
Solution
Built a TypeScript K6 framework that tests two layers side by side:
k6/http for document and asset delivery, and k6/browser for real login flows measuring Core Web
Vitals. Smoke, load and stress profiles ramp from 1 to 200 virtual users against custom thresholds,
with HTML/JSON reports and live Grafana dashboards via Prometheus.
