Cover image for MCP Market is the financial

MCP Market is the financial operating system for AI agents. Launching end of February 2026, it's the first platform that lets autonomous agents actually buy and sell stuff—think Stripe meets AWS billing, but for intelligent software. It solves the extension payment crisis (Chrome killed their payment system), enables agent-to-agent commerce with crypto rails, and meters AI resource usage down to fractions of a cent per API call. Developers can monetize their agents with granular pay-as-you-go pricing while users get "kill switch" budgets to prevent rogue agents from draining their wallets. It's cloud-grade billing infrastructure accessible to individual devs, bridging local AI runtimes with global payments through both fiat and USDC.

Luxury Jewelry E-Commerce Website – Gemsparx Front-End & Full-Stack Developer (React & Node.js) Gemsparx is a luxury jewelry marketing and e-commerce website designed to showcase diamonds, fine jewelry, and custom design services with a high-end user experience. I developed this project using React for a fast, responsive front end and Node.js for backend functionality.

The website features structured product categories, promotional sections, custom design workflows, and a modern UI optimized for both desktop and mobile users. This project demonstrates my ability to build premium marketing websites that align with luxury brand aesthetics and business goals.
