Piyush S.

Software Development Engineer in Test with 5 years of experience building test automation frameworks that catch real bugs before they ship to production. WHAT I DO I specialize in Playwright with TypeScript for modern web and SaaS applications. My work covers the full QA lifecycle — designing test strategy, building automation frameworks from scratch, integrating tests into CI/CD and delivering release-ready quality assessments to product teams. Recent work includes: - Leading a Selenium-to-Playwright migration of 100+ tests at my current role, focused on eliminating flakiness through resilient selector strategies, proper test isolation, and CI-first design. - Running end-to-end QA on a UK-based healthcare SaaS engagement covering authentication flows, role-based access control, multi-tenant data validation, and third-party integrations (Stripe-adjacent payment flows, Firebase, third-party APIs). - Building a custom QA dashboard that surfaced bug visibility across product modules for the founding team. WHERE I ADD VALUE Framework architecture. I build test suites that scale — proper POM design, custom fixtures, parallel execution, cross-browser coverage, and clean CI integration via GitHub Actions or Jenkins. Flaky test rescue. I've made a career out of turning brittle Selenium suites into stable Playwright ones. If your CI is red more than it's green, that's a solvable problem. AI-driven product testing. I hold the ISTQB Testing with Generative AI certification and have hands-on experience validating LLM outputs — hallucination detection, semantic validation, consistency thresholds, and property-based testing for non-deterministic systems. API testing. Playwright APIRequestContext for modern stacks, REST Assured with Java for enterprise. Public frameworks for both on my GitHub. MY STACK Primary: Playwright, TypeScript, JavaScript, Node.js, GitHub Actions Secondary: Selenium, Java, REST Assured, TestNG, Postman, Jenkins, Docker Tooling: VS Code, Chrome DevTools, Jira, Confluence, Sentry, Allure Reports I also have earlier experience in industrial networking QA from work on Belden's Eagle routers and Hirschmann switches — familiarity with protocol-level testing (ARP, NAT, VLAN, VRRP), Scapy for traffic manipulation, and network security fundamentals. Useful for teams working on network security products, IoT platforms, or industrial applications. CERTIFICATIONS - ISTQB Foundation Level Certified Tester - ISTQB Testing with Generative AI PORTFOLIO Three public production-quality frameworks on GitHub: github/PiyushSinghal-QA - playwright-automation-framework — Full UI automation with POM, fixtures, parallel execution, cross-browser (Chromium/Firefox/WebKit) + mobile viewports, GitHub Actions CI - playwright-api-tests — API testing with Playwright's APIRequestContext + JSON schema validation using Ajv - rest-assured-api-tests — Enterprise Java stack with REST Assured, TestNG, Allure reporting HOW I WORK I show visible progress every day I'm on a project. Daily or weekly updates depending on your preference. Bug reports include clear reproduction steps, expected vs actual behavior, evidence (screenshots, network captures, console logs), and severity classification. I ask questions early when scope is unclear rather than making assumptions. Available full-time (40+ hours per week). Based in India (IST), comfortable overlapping with US, UK, EU, and APAC business hours. Happy to jump on a quick call to discuss your project.
