👋 Hey, I’m — @sd0xdev

AI-native engineering leader with an “AI as default” delivery system. Since 2025, I’ve standardized spec-driven implementation, automated reviews, and test generation using Claude Code/Codex/ChatGPT—turning ideas into production reliably with measurable quality gates.

Full‑stack architect & polyglot engineer with 8 + years building and scaling cloud‑native SaaS across GCP, AWS & Nutanix. I combine multi‑stakeholder communication, cost mindfulness, and a quality‑first mindset to deliver products that embody Excellence & Integrity.

Current — Backend Engineer @ OneKey · owning foundational backend services and onchain infrastructure, driving reliability, scalability, and production-grade delivery for blockchain-facing systems. Led a 200K+ LOC refactor, expanded automated coverage by thousands to tens of thousands of tests, and standardized an AI-first spec-to-implementation workflow with measurable quality gates.
