About me

I'm a Computer Science (AI/ML) undergraduate at MAIT, Delhi, but most of what I know comes from shipping. I started with freelance MERN builds and internships, then moved toward the parts of software I enjoy most: backend architecture, data models, integrations and AI that has to work on real traffic.

Today I co-lead engineering at Evoc Labs, where I took Orbit 360 from an empty repository to a platform with a merchant dashboard, admin console, storefront and API, built with a team of more than twenty contributors. Alongside it I build voice and multi-agent AI systems in Python.

Orbit 360 overview

  1. 01 · The brief

    From hello world to production

    Small D2C brands in India stitch together a store builder, a courier aggregator, a payment gateway, an ads manager and WhatsApp tools, then reconcile data across all of them by hand. Orbit puts those workflows on one platform with one data model, so a merchant can go from sign-up to a live branded storefront and run daily operations in one place.

  2. 02 · Brands

    Merchant dashboard

    Catalog, orders, logistics, marketing, website editor, wallet and Seller AI.

  3. 03 · Evoc Labs team

    Admin console

    Brand onboarding, support tickets, merchant credentials and platform analytics.

  4. 04 · Shoppers

    Storefront

    The storefront is a static shell that renders whichever brand owns the incoming hostname. It resolves the subdomain, fetches that store's catalog, theme, navigation, announcements and legal pages from the public storefront API, and renders them. A new brand needs no new deployment.

  5. 05 · All three apps

    API & workers

    One Express API and one PostgreSQL schema serve three Next.js apps, a merchant dashboard, an admin console and a storefront that resolves the tenant from the request's hostname.

  6. 06 · Seller & Customer AI

    AI that only sees what it should

    Both assistants use a tool-calling loop over a shared LLM client. The model never writes SQL. It picks from a small set of validated, read-only tools, and the server injects the merchant or store identity.

  7. 07 · Integrations

    Built for Indian D2C

    Cloudflare domains, PayU, Shiprocket and iThink logistics, Meta and Google Ads, and WhatsApp, wired into one data model.
