What I'm looking for

I'm looking to continue testing Web3 and fintech products, especially cross-chain, DeFi, wallet, API, and smart contract flows, while growing further in Web3 security and secure protocol design.

I've tested cross-chain transaction flows, wallet integrations, and API behavior at CrossCurve / EYWA, a decentralized trading and liquidity aggregation protocol spanning multiple blockchains.

I investigate production issues reported by users and partners, reproduce integration failures, and use RPC logs, API calls, blockchain explorers, and Dune Analytics to understand on-chain behavior. I also create test plans, regression suites, and edge-case scenarios while acting as a QA bridge between support and engineering teams.

Previously at Geniusto Fintech, I tested payment, onboarding, payment gateway, and identity-verification flows, maintained test cases for more than 100 core banking workflows, and mentored junior QA engineers.

I'm expanding my Web3 security knowledge through Cyfrin, with a focus on smart contract vulnerabilities, secure protocol design, and DeFi risk analysis.
