Senior engineer, 10+ years, ex-Google, top 1% on Upwork. I'm Peter. I own the testing process end to end, the part that keeps products from breaking in front of real users. I also develop production software full-stack, so I can build what you need, not just test it. What I build: - QA: test strategy, Playwright, Selenium, Cypress, Postman, web, API and mobile testing, CI/CD gates, flake reduction - Software: full-stack products, Supabase, clean integrations, AI features where they actually earn their place - Automation: workflow automation with n8n and Make to take repetitive work off your team What that has looked like: - Trusted by Braze, Nestlé and 40+ SaaS companies shipping on tight, frequent release cycles - Playwright suites running in CI that gate every release - An ISTQB-certified team behind me, all held to one quality bar - Products live in production, like a recruiting agent that screens candidates end to end and a flight search bot running on WhatsApp and Telegram Who I work with: startups and mid-sized teams across SaaS, fintech, telecom, medtech, accounting and hospitality. I know where these products break. Payment edge cases, permission boundaries, flaky releases, silent data bugs. I test and build to keep them out of production. You deal with me directly, every time. When scope grows I bring in a small senior team I trust, held to the same bar. Tech-agnostic is in the DNA, I pick the stack that fits your product. Whether you need someone to keep your releases from breaking or to build something that survives real users and not just a demo, send me a message. I'd like to hear what you're working on.
