What I'm looking for

I’m looking to help teams ship safely with automation that embeds into CI/CD, targets microservices and distributed failure modes, and uses performance gates (k6/JMeter) to improve reliability—preferably remote or hybrid in Canada.

I’m a Senior QA Automation Engineer with 5+ years of hands-on experience designing test automation strategy for microservices-based, distributed systems in fintech and enterprise environments. I focus on Playwright/TypeScript, BDD/Cucumber, API and contract testing, and performance engineering to keep quality measurable and reliable.

At Zensurance, I built the QA automation capability from the ground up—owning the full test strategy for a distributed microservices insurance platform. I reduced end-to-end regression cycle time by 40%, improved backend integration reliability by 35%, eliminated 100% of recurring onboarding-flow defects across three releases, and cut flaky test rate from 18% to under 3% by targeting distributed workflow timing and async failure modes. I also mentor engineers and set quality standards across cross-functional teams by embedding automated testing into CI/CD pipelines.

Previously at Railz, I expanded REST API test coverage from 52% to 91%, detected 23 critical data consistency defects before production, validated event-driven pipeline correctness with fault-injection scenarios, and reduced API regression execution time by 55% through parallelized collections. Earlier at Infosys, I decreased regression execution time by 30%, uncovered 40+ cross-system data integrity defects, and guided manual QA analysts into automation using Selenium/Java and PyTest. I’m also deep in performance and reliability work—building k6/JMeter suites, SLA baselines, and real-time CI gates to catch issues fast.
