Building Systems
That Actually Ship

I'm a Full Stack and Desktop Developer who architects and ships complete production systems. My focus is on real-time WebSocket architectures, serverless cloud infrastructure, and native desktop applications.

Building at Amagle Software, where I architected a healthcare QR emergency ID platform. Also shipped PrintStudio — a B2B SaaS print automation platform with Cloudflare's distributed backend, Razorpay billing, and an Electron desktop client.
