Quality Engineer (Web3 / Blockchain)

Quality Engineer specialized in the reliability and correctness of Web3 systems, focusing on wallets, transactions, swaps, and multichain environments.

I validate end-to-end transaction flows, from construction and signing to network submission and on-chain confirmation, identifying failure modes that could lead to silent errors, degraded UX, or irreversible user loss. My work spans both EVM and non-EVM networks, including complex multichain scenarios and edge cases.

Contributed to a major wallet revamp (XDEFI → CTRL), ensuring transaction safety, wallet behavior consistency and transition, also regression coverage across critical user flows

My hands-on testing also includes hardware wallets such as Ledger and Trezor, comparison with different hot wallets, and Walletconnect.

While focus is on manual and system-level QA, I am definitively open to gradually expanding into automation over time, complementing my practical understanding of real system behavior.

Maintains a quiet, rigorous, and dependable approach, with strong attention to user safety, fund protection, and product trust, and collaborates closely with teams to ensure practical outcomes (product owners, developers, designers, and customer support).
