Senior Full Stack Engineer

I’m a Senior Software Engineer, Web3 Product Engineer, and AI-Augmented Product Engineer with 7+ years of software engineering experience, specializing in full-stack product development, blockchain systems, AI agent workflows, and developer-facing platforms. My work spans React, Next.js, TypeScript, Solidity, NestJS, Hono, Go, Python, Playwright, Synpress, Wagmi, Viem, Ethers, Hardhat, Foundry, PostgreSQL, Docker, Vercel, GCP, and Kubernetes — with experience shipping production features across Web3 infrastructure, DeFi integrations, AI-powered products, admin dashboards, blockchain explorers, and internal tooling.

Most recently, I contributed across AltLayer’s ecosystem on products such as Wizard, Autonome, Rumour, 8004scan, AltLLM, and AltClaw, covering frontend implementation, backend/API work, architecture refactoring, responsive UI, E2E testing, MCP/Web3 tool integrations, and production support. I’m strongest when turning ambiguous product requirements into reliable, maintainable systems, working closely with founders, product teams, and engineers to ship fast without losing engineering quality. I’m especially interested in teams building at the intersection of Web3, AI agents, DeFi, developer tools, and product-led engineering.
