Hi there, I'm Jafin Jahfar 👋

I'm a Principal Engineer and AI Consultant who loves building end-to-end software solutions that solve real-world problems. My journey started as a self-taught developer from India 🇮🇳, and has led me to architecting scalable systems and building AI-powered products.

🚀 What I'm Currently Building:

• B24: A multi-tenant WhatsApp sales-automation SaaS — an AI sales agent and a full lead pipeline that runs on each business's own WhatsApp Business number. It captures every lead, qualifies and quotes, follows up automatically, and hands warm leads to a human team — in 5 languages, with a per-tenant RAG knowledge base so the AI answers only from the business's own content.

• SellScript AI: An AI co-pilot that turns customer reviews into actionable product insights for E-commerce sellers. I'm currently leading the development of the MVP, which is set to launch by the end of 2026.
