What I'm looking for

I’m looking for a Full Stack role where I can build scalable products end-to-end—modern React/Node systems, EVM smart contracts, and AI workflow automation. I want to grow in system design, performance, and real-world agentic experiences.

I’m a Full Stack Developer focused on building scalable web applications and blockchain-based systems. I enjoy turning complex product requirements into reliable frontend and backend implementations.

Recently, I developed an agent payment and API marketplace (afx402) using TypeScript, Next.js, Solidity, and EVM smart contracts. I implemented the x402 (HTTP 402) payment flow for pay-per-call APIs, prepaid balances, subscriptions, and autonomous agent transactions.

I also built an ecommerce platform featuring secure OAuth authentication, product and shopping cart flows, MongoDB-based data storage, and a Razorpay-integrated checkout experience. For interactive learning, I created a Wireless Communication Visualizer using React + Vite with D3.js, p5.js, and Three.js.

I’m equally comfortable with system design, performance optimization, and REST API design. I’m especially interested in AI workflow orchestration and agentic AI systems—bringing automation to real products with thoughtful architecture.
