Work experience

QA Engineer · AI Architect

from 03.2023 to now (3 years 5 months)
Thrivestate, Дистанційно (IT)

I build the AI that does the QA.

Most teams shipping LLM and GenAI features hit the same wall: their existing QA breaks. Non-determinism, hallucinations, evaluation gaps. The deterministic playbook doesn't translate.

I design orchestrated multi-agent systems that run the testing lifecycle and hold quality in production, release after release. The outcome teams feel: releases that ship faster, and a QA budget that stops growing with the headcount.

My background runs from enterprise QA (Deloitte, Tietoevry, Infopulse) to AI-first products, where I built an AI-driven QA test-management system from scratch. On a live product the same QA team roughly doubled its throughput, bugs reaching production dropped about 80%, and manual validation effort about 70%.

What I can build for you:
• Evaluation frameworks for LLM features: precision, recall, hallucination rate, drift
• Multi-agent test pipelines that handle non-deterministic output
• Quality gates from prototype to production
• Test automation: Java/Selenide UI, RestAssured API, CI/CD
• Risk analysis at the edges of AI reliability
