QA Engineer

Six years in QA on products that don't forgive mistakes: iGaming, blockchain, LLM agents. Leading 14 engineers at SprutGaming — 21 microservices, Go, Kafka, payment flows with real money. Came from frontend, so I read code and find root causes — not symptoms. First in the company to introduce AI-assisted QA as a formal standard. I build quality as a system property, not a pre-release checklist.

• –I read code, not just UI — came from React/Next.js frontend. I find the root cause of a bug in minutes, not hours.
• –Tested non-standard products with no existing playbooks: L2 ETH DEX, LLM chat with agents, crypto platforms — wrote the approaches from zero.
• –iGaming scale: 21 microservices, payment integrations (crypto invoice, H2H, fiat), Go services, Kafka, Kubernetes. Bugs in payments are real money.
• –First in the company to introduce AI-assisted QA: LLM DB migration verification, Cursor IDE + Claude + Figma MCP. A company standard since 2025.
• –Built QA from scratch twice: zero coverage to full cycle — checklists, test cases, AC review, smoke + e2e, DoD — in 6 months.

   QA Lead · SprutGaming

   Team of 14 (9 core + 5 contractors). Built processes from zero, onboarded 8+ engineers, syncs with CTO 3× a week.

• →Become a public voice on AI-assisted QA — it's a hot topic with almost no quality content yet.
• →Shift-left as a cultural norm: quality is designed into requirements, not patched after release.
• →Grow engineers who think in systems and risks — not ones chasing task counts.
• →Cut escaped defects and MTTR through observability, automation, and ownership culture.
• →Build teams that run without my hands-on control — because good processes scale, managers don't.

• AI-assisted QA — company regulation, not a pilot
