Rahul Nair

I am a remote QA Engineering Manager and Senior SDET with 10+ years of hands-on experience building backend automation frameworks from the ground up. For the last 5 years, I have worked exclusively for a blockchain product company, securing multichain self-custody wallets, stablecoin systems, and NFT marketplaces.

My core technical focus covers:

• Web3 / Blockchain Core: Running local validators and simulation tools (Tenderly, Hardhat local forks, Solana Test Validator, Blockfrost) to catch complex on-chain edge cases like gas spikes, re-orgs, indexer lag, and slippage deviations.

• Integrations & Hardware: Protocol-level verification for Ledger and Trezor hardware wallets (USB/BLE), dApp connectivity (CIP-30), and multi-hop fiat-to-crypto payment rails.

• Backend & UI Automation: Architecting multi-step API chaining and E2E suites using Playwright, TypeScript, Rest-Assured, Maestro, and Docker-based setups.

• AI Infrastructure: Building agentic testing workflows using Claude Code and Model Context Protocol (MCP) to autonomously generate and maintain dynamic regression code.

Beyond code, I spend my time running open-source experiments around self-healing test frameworks and LLM-as-a-judge evaluation sandboxes. I actively manage and participate in the crypto market as an investor, which allows me to approach protocol quality assurance with a deep understanding of user friction, security bugs, and decentralized transaction structures.
