I take ideas from a blank page to commercial products. Backend systems, applied language AI, and the product judgment to know what is worth building.

The short version

I have spent my career inside young companies, building the first working version of things that did not exist yet.

That path runs from IoT hardware, through language models and a recruitment automation product, to the logistics platform I now lead as CTO. Along the way I started a fintech venture of my own, which taught me to think about a product from the balance sheet backward as well as from the code forward.

What ties it together is a habit. I start from what the customer and the operation actually need, make the technical call that serves it, and keep the result reliable enough to run a business on.

Currently building

June 2026 to present · CTO and Product Lead

Pinak AI Solutions

Products currently in development

QuickGlobalquickglobal.in International shipping platform. It supports the operation from first dispatch through final delivery, with shipment tracking and clean data flow at every step. QuickLookquicklook.in Built alongside QuickGlobal. It carries the same dispatch-to-delivery tracking and data flow, so shipment information stays accurate end to end.

As CTO and Product Lead, I am responsible for the engineering and product direction of both platforms. The objective is a shipping system that is reliable, scalable and ready for commercial use, with every stage of a shipment traceable from dispatch to delivery.

How a shipment moves through the platform

  1. 01DispatchShipment enters the system with the data it needs to travel.
  2. 02TrackingStatus is captured and surfaced as the shipment moves.
  3. 03Data flowInformation reaches every part of the platform that depends on it.
  4. 04DeliveryThe loop closes with a clean, end-to-end record.

What I own

  • Technical architecture and backend systems
  • Product direction, from concept to shipped feature
  • The trade-off between customer needs, operations and growth

Outside work

I keep building software for fun, usually to solve a small problem I ran into. When I am away from the keyboard I read, run, meditate, make music and vlog.

Let's talk

Have something that needs to exist?

I am open to senior software engineering and product roles, and to conversations about building something new.
