OLEH FEDORTSOV
QA Engineer with 8+ years of hands-on testing across worldwide enterprise products — mobile, web, and API systems spanning AdTech, FinTech, Enterprise SaaS, social gaming, and AAA game development. Currently leading regression strategy on a global advertisement platform with ML/AI integrations at SoftServe, mentoring a six-engineer team.
Quality assurance practice spanning eight years across five industries — from AAA game development through FinTech, Enterprise SaaS, social gaming, and large-scale advertising platforms. The work covers the full QA cycle: requirements analysis, test design, manual execution across mobile, web, and API surfaces, defect lifecycle management, regression strategy, and quality metrics that inform roadmap decisions.
Focus areas include test architecture for distributed microservices, validation of integrations with ML/AI services, and end-to-end coverage of business-critical flows where data integrity is non-negotiable.
Responsibilities extend beyond execution: leading a team of six QA engineers, conducting technical interviews, onboarding new team members, and standardizing documentation templates that scale across the organization.
