01 — About

I'm Vashisth Bhushan — a full stack engineer and founder based in Gurgaon, India. I've spent nearly a decade at the intersection of product engineering and design, building things that actually ship and scale.

Most recently as SDE-3 at Beem (Line Financial), I led a team of 7 building fintech infrastructure for 5M+ users — AI-driven personalisation, dynamic pricing, multi-LLM pipelines, and real-time lending systems. Before that, I worked across Web3, blockchain, and consumer platforms.

In parallel, I run A Design Guy (ADG) — a full-service web & product studio awarded Best Bespoke Agency 2024, South Asia. And I built CallsupAI — an AI customer support platform with RAG pipelines, voice AI via ElevenLabs, and multi-tenant architecture.

I'm fluent across the stack: React Native to Node.js backends, LLM integrations to Shopify Plus — and I hold a B.Tech in Information Technology from Manipal University.
