Insurance Inbound Voice AI Appointment Setter Petr showed a good understanding of the requirements, but the project took longer than expected, and due to our client’s delivery timeline we had to adjust our approach and move in a different direction. I appreciate his effort and wish him success in future collaborations; we might work together again in the future under less time-sensitive conditions.

AI Automation + Playwright QA Engineer | n8n, Claude, GDPR
75% Job Success
5.0  (7 reviews)
Ceske Budejovice, Czech Republic - 6:32 am local time
I build production systems that don't break at 2 AM — Playwright test infrastructure, AI automation that survives real users, and cookie/consent compliance audits with evidence you can hand to a lawyer.

For the last 4+ years I've owned production Playwright + TypeScript test infrastructure across 6+ major Czech media websites at Devcity: smoke tests, post-deploy checks, shadow monitoring, E2E suites, AI-assisted failure triage, Grafana + OpenSearch dashboards, GitLab CI/CD, Slack reporting, and Better Ads Standards compliance testing. I also publish open-source developer tools and AI products under my own name.

────────────────────────
WHAT I OFFER ON UPWORK
────────────────────────

→ Playwright Production Monitoring — smoke + critical-flow tests, CI integration, Slack alerts, HTML reports, flaky-test triage. Recurring retainer available.
→ Cookie / Consent Compliance Audit — I test whether your banner actually blocks cookies before consent. Evidence screenshots, cookie tables, risk summary, engineering fixes. GDPR / ePrivacy / TCF.
→ AI Exploratory QA Audit — 25 AI personas explore your app in real Playwright browsers, surface edge cases and risks, output deduplicated reports + Playwright starter tests. Powered by my open-source tool breakit.
→ Custom AI Automation — voice agents, chatbots, lead workflows, document pipelines. n8n, Claude API, OpenAI, VAPI, Twilio.

See my productized projects below for fixed-scope pricing.

────────────────────────
PROOF, NOT JUST DEMOS
────────────────────────

- Complicer — production compliance SaaS with bounded AI (Playwright engine, 65 rules, audit trails, SARIF artifacts)
- breakit — open-source AI exploratory testing with Playwright + 25 AI personas
- KindLM — YAML behavioral regression tests for LLM agents (CI-native, JUnit XML, EU AI Act mode)
- pw-doctor — published npm CLI that heals broken Playwright selectors (5 repair strategies + AI fallback)
- N8Calls — 19 live AI automation templates (voice agents, chatbots, lead workflows)

Linked from my Upwork portfolio and GitHub (under "Linked accounts") for code samples and demos.

────────────────────────
STACK
────────────────────────

Web — Next.js (App Router), React, Tailwind, Cloudflare Workers, D1, KV, R2, Postgres, Prisma, Supabase
Compliance — GDPR / ePrivacy cookie audits, TCF v2, Better Ads Standards, accessibility (WCAG), evidence-based reporting
Crypto / Web3 — early adopter and ambassador (Nxt Cryptocurrency 2014-2017, Blockchain Evangelist 2015-2020). Open to crypto, web3, DeFi, exchange, and on-chain projects.

────────────────────────
HOW I WORK
────────────────────────

- Fixed-scope productized offers below — clear deliverables, set price
- Custom builds: working demo in 48 hours before you commit budget
- Full documentation + handoff — you own everything, no lock-in
- Retainer available for monitoring, triage, and ongoing changes
- Available 30+ hrs/week, EU & APAC-friendly hours, average response 0–4 hours

I'm Czech-based, fluent in English (Czech native, German conversational), and open to both short fixed-price projects and longer engagements / contract-to-hire.

────────────────────────
NOT A FIT IF
────────────────────────

You need gambling/sports-betting, adtech tracking workarounds, or "rebuild Twitter in two weeks." I prefer focused work where quality matters — production reliability, audit trails, real testing.
