Test Automation
Expertise in building and owning end-to-end test automation frameworks using Playwright, Cypress, Selenium WebDriver, REST Assured, Cucumber, and Gherkin across frontend and backend systems in regulated fintech, blockchain, and logistics environments.
API & Contract Testing
Strong proficiency in REST API testing, Pact-based contract testing, microservices testing, and blockchain interaction validation, ensuring reliable integrations across complex distributed architectures.
CI/CD & DevOps Integration
Hands-on experience integrating automated test suites into CI/CD pipelines using Jenkins, Azure DevOps, and GitLab CI, with containerized testing via Docker and observability through Datadog, Sentry, and Kibana.
Performance Testing
Practical experience in performance and load testing using k6 and JMeter to validate application resilience under varied load conditions.
Programming Languages
Proficiency in TypeScript, JavaScript, Java, and Python for writing clean, maintainable automated test code across multiple projects and platforms.
Shift-Left Testing & Test Strategy
Proven track record of driving shift-left testing approaches, defining test strategies, test planning, and introducing automation-first cultures within development teams.
Visual & Cross-Browser Regression Testing
Experience with visual regression testing using BackstopJS and cross-browser/cross-platform testing to ensure consistent UI quality across environments.
AI-Assisted QA
Early adopter of AI-assisted testing tools including Claude Code for AI-driven unit test generation and QA tooling Proofs of Concept, achieving over 80% unit test coverage across multiple components.
Agile/Scrum Practices
Extensive experience working within Agile and Scrum teams, collaborating with developers, product owners, and compliance teams to deliver secure and stable releases.

Project history
Sole QA engineer holding end-to-end quality ownership across every product surface including KYC, dividend flows, tokenization, and the core platform API for a blockchain platform for compliant asset tokenization and regulated secondary trading. Built and owned the entire testing strategy from the ground up, led a full framework migration from Cypress to Playwright (TypeScript) cutting regression time by more than 60%, increased unit test coverage to over 80% using AI-assisted test generation with Claude Code, and led Proofs of Concept for QA tooling including API testing for microservices and blockchain interaction validation.
Drove a shift-left testing approach within the Risk & Compliance domain for a payment solutions provider powering 2,500+ platforms globally. Developed and implemented robust end-to-end automated tests using Playwright and TypeScript, migrated existing Cypress tests to Playwright achieving a 50% improvement in test execution speed, and validated application resilience under load using k6 with performance monitoring through Kibana.
Owned and evolved the QA test strategy for the Order Processing Team on a shipping automation platform connecting 80+ carriers via API and 50+ integrations. Implemented contract tests with Pact and Python, E2E automated tests with Playwright and TypeScript, monitored releases in a high-velocity CI/CD pipeline using Datadog and Sentry, and tested features against containerized applications with Docker.
