Building real-time, distributed & AI-powered systems.

I'm a Full Stack Software Engineer at Leadchain Systems, where I build scalable real-time, distributed, and AI-powered systems — spanning WebRTC/Mediasoup infrastructure, WhatsApp messaging, BullMQ/Redis background processing, AWS S3 media pipelines, multi-tenant SaaS architecture, and RAG/conversational AI systems. Outside of work, I'm building nerdShare — a privacy-first P2P file-sharing platform — and Kebo, a keyboard-first command interface for Chromium browsers.
