## 1. Executive Summary & Core Identity

VISTAR is a founder-led engineering studio based in New Delhi, India. We engineer high-performance web applications, bespoke business platforms, WhatsApp conversational workflows, and interactive 3D WebGL experiences.

Unlike traditional marketing agencies that assemble fragile templates or deliver slide decks, VISTAR operates as a focused technical partner. Every project is engineered directly with modern tools (Next.js, TypeScript, PostgreSQL, Tailwind CSS), deployed on edge-native cloud infrastructure (Vercel, AWS, Cloudflare), and handed over with complete GitHub repository rights on day one.
