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.

Cover image for A full-stack personal productivity app

A full-stack personal productivity app built for daily use ,not as a demo, but because I actually needed it. The app has a three-part daily journal (morning planning, midday check-in, evening reflection), a meal planner, a habit tracker with streaks, a recipe journal, and a weekly summary view. Every tab has a built-in AI assistant powered by Claude that knows your context ,what you planned, what you ate, what habits you're tracking — and gives grounded, specific help instead of generic responses. Built with Next.js, TypeScript, Drizzle ORM, Neon (serverless Postgres), and the Anthropic Claude API with streaming responses. Designed mobile-first as a PWA so it installs on your phone like a native app. The kind of project that only gets built when you're solving a real problem for yourself.
