Data-driven, risk-based QA for financial systems, data migrations and digital transformation, with 15+ years of international experience in fintech, banking, energy and telecom. I bridge data engineering teams and business stakeholders, and I check that systems, data and AI-generated output actually do what they claim.

How I work
- Detail-oriented and precise: I follow specifications closely and catch the inconsistencies others miss.
- Self-motivated and reliable: I deliver consistent quality without supervision.
- Independent and asynchronous: I manage my own schedule and workload, with experience on fully remote teams across time zones.
- Research and root-cause analysis: I trace issues back to source systems and cross-check findings before reporting them.
