Four things worth reading about.
Enterprise systems, from the data model up.
At Vertiv I work on a multi-tenant infrastructure cloud and a long-running monitoring platform — NestJS services, PostgreSQL modelling, a dual REST and GraphQL API surface, graph traversal in ArangoDB, and a query layer designed for AI assistants to use reliably.
Enterprise work — visuals abstracted and details generalised for confidentiality.

GraphQL asset graph
Natural-language questions resolve into structured infrastructure queries through an introspectable schema.
Asset hierarchy — traversal model

Multi-hop questions across this hierarchy are expressed as graph traversals in AQL rather than recursive SQL — and the same shape is what an assistant queries through GraphQL.

VRRentals.in
A VR hardware rental and immersive technology business serving events, exhibitions, product demonstrations, corporate activations and training. It is also a product I built — catalogue, booking, payments, dashboards and admin workflows.

Building beyond screens.
I'm increasingly interested in software that interacts with the physical world — immersive training, spatial interfaces, simulation and real-world workflows.

Build things that leave the screen.
Software gave me a way to build systems. Entrepreneurship showed me how people actually use them. XR made me interested in what happens when software moves beyond a browser and becomes part of the physical experience.
That's the intersection I'm increasingly interested in exploring.
Let's build something interesting.
Building software, exploring immersive training, planning a VR deployment, or working on something unconventional? I'd like to hear about it.
