About me

Building at the frontier
of human–computer
interaction

I'm a multidisciplinary engineer working at the intersection of immersive technology, artificial intelligence, and autonomous robotics. My work spans from crafting precise AR/VR experiences to shipping AI-powered products at scale.

With a background in software engineering and robotics, I care deeply about systems that are both technically rigorous and genuinely useful to people. Whether it's a real-time spatial computing app or a deployed ML pipeline, I focus on things that work.

Currently based in Bristol, UK — open to remote collaboration globally.

Selected work

Projects & experiments

A collection of work spanning immersive tech, AI products, and robotics systems.

WebXR

FireXcape

A WebXR fire safety training tool that simulates real-time fire spread and escape route navigation on a 3D Gaussian Splat scene rendered in the browser. Built for building managers and safety officers who rely on static PDFs and repetitive drills — FireXcape shows what actually happens when fire spreads and panic sets in.

AtithiXR

A personalised AI travel planner for Meta Quest that profiles your travel persona and suggests three tailored journeys. Explore each destination in VR — its history and charm through interactive experiences — then receive a detailed itinerary straight to your inbox.

ARchive — AR Time Travel Explorer

A smartphone AR tourism app that reconstructs historical ruins at their original site using your camera. Scan a monument, see the original building rebuilt in AR, watch a simulated history of the site, then ask an AI voice guide anything — like talking to a human expert on location.

WebXR

MemoReal — 2D Image to 3D VR Scene

A WebXR app that converts single 2D photos into walkable 3D point-cloud environments rendered on WebGPU, letting you relive memories in VR with others. The demo narrates a story through memory fragments — each image unlocking a reconstructed immersive scene.

War of Tarot — Multiplayer AR Battle Game

A multiplayer AR card battle game where tarot cards come to life as 3D characters in your physical space. Players engage in strategic real-time combat, casting spells and activating unique abilities to defeat opponents — all anchored to the real world via AR.

RiseVR — Multiplayer VR Racing Game

A fast-paced multiplayer VR racing game in a vertical 3D arena with Mario Kart-style gameplay. Players navigate using jetpacks and grapple guns, competing with power-ups to reach the finish line first — built with full game-state synchronisation across players.

360° Film

Beyond the Grey — 360° Short Film

A short 360° POV film narrating the lived experience of an international student arriving in an unfamiliar city — shot with the Insta360 ONE X2 and edited in Insta360 Studio and DaVinci Resolve.

Magic Mirror — 3D Spatial Audio in VR

A VR experience exploring 3D spatial audio design. A magic mirror in a washroom changes the acoustic environment based on items the player picks up — grabbing a broom transforms the space into a concert hall; a tube transports you to a Star Wars desert soundscape.
