Afrin Ameer Khan — QA Engineer & SDET

01 About

A QA engineer who thinks like a developer.

I design test strategies that catch defects early and automation frameworks that scale with the product — written, reviewed, and maintained like production software.

Over the past four years, I've shipped critical software in regulated domains where reliability isn't optional. From validating EHR communication and insurance eligibility flows in healthcare, to securing payment gateway transactions in FinTech, to verifying real-time IoT telemetry over Kafka streams in automotive — I've learned that quality is a discipline, not a phase.

I take ownership of the test pyramid end-to-end: writing maintainable Selenium and Appium frameworks in Java, integrating them into Azure DevOps pipelines, validating APIs with REST Assured and Postman, and mentoring junior QAs along the way. Lately I've been exploring how prompt engineering and AI tooling can accelerate test data generation without sacrificing edge-case rigor.

Where I've delivered.

Jan 2024 — Jan 2026 Healthcare & Automotive Current

Quality Assurance Engineer

UST

Designed and led the automation strategy for the Patient Inquiry & Appointment System, reducing regression cycle from 3 days to 4 hours per release.
Built a Selenium WebDriver TestNG framework (Java, POM) covering Patient Registration, Claims, and Inquiry validation modules.
Implemented data-driven testing with Apache POI to validate patient and insurance data from Excel sources.
Validated APIs for eligibility checks, insurance lookup, and EHR communication using Postman + Newman CLI.
Integrated UI & API suites into Azure DevOps pipelines with nightly regression triggers — 40% reduction in manual effort.
Added SonarQube static analysis to the pipeline, improving automation code quality and reducing tech debt.
Automated IoT telemetry validation over Apache Kafka — verifying engine status & GPS streams from vehicle sensors to cloud.
Applied prompt engineering to generate synthetic patient profiles, accelerating coverage of complex healthcare scenarios.
Led KT sessions and mentored junior engineers on automation frameworks and QA standards.

Jul 2022 — Dec 2023 E-commerce & Banking

Test Engineer

WhiteRabbit Group

Owned full STLC across requirement analysis, test planning, design, execution, defect tracking, and RTM under Agile/Scrum — supporting bi-weekly releases and reducing post-production issues by 35%.
Designed end-to-end e-commerce test cases (Registration → Login → Cart → Checkout → Payment → Order History) — improving stability by 35% across web and mobile.
Applied EP, BVA, and Decision Table techniques for auth and OTP scenarios — 40% drop in login/registration defects.
Validated cart/checkout integration: pricing, shipping, coupons, sessions, cross-browser — 28% fewer checkout failures.
Tested FinTech payment gateways: success, failure, timeout, rollback, OTP expiry — 30% drop in payment incidents, 32% less defect leakage.
Performed API validation with Postman to ensure data consistency across UI, API, and DB layers.
