Senior QA. AI-accelerated.
No agency overhead.

One engineer. Thirteen years of shipping quality. Here's who you're actually working with.

Serhii Kryvokhatko

Senior QA Engineer & Consultant

Seven years building QA teams at PAR Technology — growing a 25-person function from the ground up — taught me one thing: quality at scale is a judgment problem, not a headcount problem. You can staff ten engineers and still ship bugs if nobody's making the right calls.

When AI tools started changing what one person could realistically do, I didn't see a threat — I saw a different kind of practice becoming possible. The leverage that unsettled large QA departments makes a solo senior engineer genuinely formidable: faster coverage, sharper analysis, independent execution — without the overhead that makes enterprise-grade quality unaffordable for most teams.

Most people in this industry are still deciding how to react. I'd rather build at the front of the shift than follow it from behind. HeyQA is that choice — AI as a real tool, not a label, in the hands of someone who's been doing this long enough to know the difference.

AI tools. Human judgment. No shortcuts.

Every deliverable is AI-accelerated and human-validated. Here's exactly how that works.

AI does
  • Generates test scenarios from user stories
  • Identifies coverage gaps across the codebase
  • Speeds up script writing and code generation
  • Flags patterns in large test result sets
  • Self-healing selectors on UI changes
I do
  • Decide what risk actually matters for your business
  • Architect the framework for long-term maintainability
  • Review and validate every AI output before it ships
  • Write the reports that tell a real, actionable story
  • Make the judgment calls AI cannot
Together
  • Faster coverage without sacrificing judgment
  • No "AI theatre" — every output is validated
  • Senior-engineer quality at a pace that was not possible before
  • You get the benefit of both, the overhead of neither
