I've owned full test cycles for non-custodial Bitcoin and TON wallets, covering Playwright automation, API validation, on-chain transactions, Ledger hardware-wallet integration, and cross-platform releases across mobile, web, desktop, iPad, and browser extensions.

Previously, I tested gambling and logistics platforms at Godel Technologies Europe, validating REST APIs, JSON, SQL databases, distributed microservices, and external-system integrations. I bring 6+ years of functional, regression, integration, and end-to-end testing, collaborating closely with developers, business analysts, product managers, and business owners through Agile delivery and UAT.
