About

Professional summary

I am a Software Development Engineer in Test with more than eight years of experience building scalable UI and API automation solutions for banking and e-commerce platforms.

I specialize in Playwright, JavaScript, Java, Cucumber, and CI/CD-driven quality engineering. My work includes end-to-end, regression, integration, cross-browser, microservices, and API validation.

In my current role, I own SIT/UAT test strategy and release readiness for a commercial client onboarding platform. I work closely with engineering and product teams to drive early validation, triage defects, and improve release confidence.

I have modernized automation frameworks, expanded UI and API coverage, improved regression reliability, and reduced test execution times through parallelization, synchronization improvements, and dependency analysis.

I also develop AI-assisted testing workflows, including automation agents that translate requirements into test plans and automated scenarios. I enjoy creating reusable testing capabilities and sharing practices through technical sessions, code reviews, and mentorship.

I am experienced in investigating complex defects using application logs, AWS observability tooling, browser debugging, and structured test reporting. I focus on shifting quality left and enabling developers to validate features earlier in the delivery lifecycle.

Career history

Software Engineer in Test JPMorgan Chase & Co.

I own SIT/UAT test strategy and release readiness for a commercial client onboarding platform. I drive early end-to-end validation, defect triage, and collaboration across engineering and product teams.

I led automation modernization from Java/Maven/Playwright/Cucumber to a standardized Playwright, JavaScript, and Cucumber framework with reusable page objects and utilities. I expanded UI and API automation coverage by 70%, improved regression reliability through synchronization, retries, parallel execution, and CI reporting, and reduced a critical end-to-end test from 60 to 40 minutes.

I developed an AI-assisted automation agent that translates JIRA requirements into test plans and scenarios, identifies existing coverage, and supports automated test generation and reviews. I also mentor QA engineers, build reusable onboarding automation skills, and investigate complex defects using AWS logs, observability tools, and browser debugging.

QA Engineer Deckers Brands

I developed JavaScript automation scripts using Selenium WebDriverIO, Mocha, and Cucumber for e-commerce platforms. I performed end-to-end functional and regression testing across Salesforce Commerce Cloud to support web and mobile customer experiences.

I optimized test execution using Shoppers APIs and OCAPI, reducing runtime by 35%. I validated order lifecycle workflows, analytics tracking, and third-party APIs while analyzing nightly regression results and conducting exploratory testing to identify release blockers.

I mentored junior QA engineers on automation practices, test case design, and defect management. I also facilitated code reviews and QA guild meetings to improve automation quality across teams.

SDET 4Stay

I built Java-based automation frameworks using Selenium, TestNG, Maven, Page Object Model, and data-driven testing practices.

I developed SQL queries for database validation and used Postman for backend API testing. I also leveraged Selenium Grid to execute tests across multiple browsers and environments.

SDET BookIT

I developed BDD and TDD automation scripts using Java, TestNG, and Cucumber.

I participated in requirements analysis and automation feasibility studies. I logged defects in JIRA and collaborated with developers to resolve critical issues.
