Stefan Florescu

QA Automation & Game QA Engineer

Profile

8+ years in QA: 4.5 years on FIFA Mobile at Electronic Arts, then full-spectrum manual QA at Iron Sheep (scripted, exploratory and A/B testing) that grew into AI-driven test automation and game QA for a US social & sweepstakes casino platform. I build Playwright automation, re-calculate game results from the rules to prove payouts are right, and use AI agents (Claude Code) to make testing faster, with the judgement about what counts as a bug kept human. AI-assisted QA is where I want to grow next.

Experience

QA Automation & Game QA Engineer · Iron Sheep (Quality Analyst)

Remote · Dec 2022 – present
ZOOT (formerly Enigma Lake) · US social & sweepstakes casino platform and its in-house games
  • Full-spectrum manual QA (scripted, exploratory, A/B) that grew into AI-driven test automation and game QA.
  • Built and maintained an end-to-end Playwright suite: ~350 tests in 61 spec files, 301 catalogued test cases, covering the platform and 44 game specs (Mines, Plinko, Tower, Crash, sports games).
  • Set up Smoke and Regression runs with TestRail reporting and a test-run dashboard; cut the Plinko suite runtime by 26% with no new flakiness.
  • Tested new games against their spec documents (~90 checks per game) and wrote GO / NO-GO release reports; a NO-GO with evidence on a feature that broke the play limits gave the team a clear basis for the launch decision.
  • Wrote independent math verifiers that re-calculate every round from the rules: 4,000+ real rounds across 6 games, 0 maths mismatches; statistical sanity checks (chi-square, z-score, Monte Carlo) on hit rates and RTP.
  • Ran release checks for batches of up to 66 games (currencies, banned wording, mobile and desktop views, max exposure) and audited the advertised max win across 144 games.
  • Tested on real Android devices over wireless ADB and the Chrome DevTools Protocol; compared ported games with the original provider versions.
  • Built and shipped the QA Companion Chrome extension (Manifest V3) used by the QA team: round log, balance checks, banned-wording scan, checklist export.
  • Defined the QA process as 10 reusable AI agent playbooks (Claude Code) for spec-based testing, release checks and test scaffolding.
  • Built Claw Machine with ZOOT’s AI game builder (Forge) from prompts and reference images; it became the template for two further games, Autumn Claw and Midnight Claw (all playable in the public ZOOT archive).
