Principal Developer, MASGARTI

Hari Sankar

Full-stack engineer who designs, ships and runs whole products, from the mobile app to the cloud it runs on.

At MASGARTI I own the architecture and delivery of the product portfolio. Before that I led an engineering pod at Rocket (formerly Mr. Cooper), one of the largest mortgage platforms in the United States, and built the core platform of Dinify, a contactless dining startup in Vancouver, as its Senior Software Engineer.

What I bring

Senior engineering that ships and stays up

Zero to production

Takes a product from architecture to a live release on iOS, Android and web, then keeps it running. Six MASGARTI products are live today.

Money and identity

Payments, loyalty, digital identity and role-based access across multi-tenant platforms, the parts of a product where mistakes cost real money.

Applied AI

Retrieval-augmented assistants and agent workflows built with Claude, LangChain and LangGraph, used where they cut cost, errors or time to decision.

Enterprise discipline

Event-driven services, Kubernetes, infrastructure as code and security reviews, carried from a regulated US lender into a startup's speed.

Experience

From a regulated US lender to a startup studio

    Current

    AI, Venture, Core and Robotics studio

    Owns architecture, delivery and production running across MASGARTI's product portfolio: six live products spanning identity, loyalty, commerce, workspaces and applied AI.

    • Sets the technical direction per product and takes each from first design to a production release on mobile, web and API.
    • Built the shared foundations the portfolio runs on: multi-tenant data models, role-based access, payments (Adyen, Stripe, Razorpay) and identity.
    • Brought applied AI into the portfolio: retrieval over company documents with Claude and vector search, and an AI-led operating review for small businesses.

    Rocket (formerly Mr. Cooper)

    Enterprise

    US mortgage lending and servicing, now part of Rocket Companies

    Led a five-person pod on mortgage origination inside one of the largest mortgage platforms in the United States.

    • Built C#/.NET back-end services on an event-driven Kafka architecture, with React front ends.
    • Built PyroAI, a document assistant that answers questions from platform documents (LangChain retrieval, LangGraph agent loop), and a document-ingest pipeline into Google Discovery Engine.
    • Deployed and operated services on Rancher-managed Kubernetes, provisioned AWS infrastructure with Terraform and integrated Microsoft Entra ID sign-in.
  3. Senior Software Engineer

    Dinify (YagnoTech Inc.)

    Startup

    Contactless dining and takeout for restaurants, Vancouver

    Built the core platform for a contactless dining startup: diners order and pay from their own phones, and restaurants run tables, menus and orders from one console.

    • Engineered the Node.js and Express API on MongoDB that both apps run on.
    • Built the React diner ordering app and the React restaurant management console.
    • Implemented sign-up and staff verification on AWS Cognito with Lambda triggers, plus payment, POS and messaging integrations (Stripe, Clover, Twilio, SendGrid).
