QuadQR
A different way to encode information. Four colors, a denser data layer, and optional encrypted payloads in a QR-inspired format.

Useful software, built with a curious mind.
01 / Selected work
Open-source libraries.
Applications that solve real problems.
A different way to encode information. Four colors, a denser data layer, and optional encrypted payloads in a QR-inspired format.
A place for the prompts worth keeping. An offline-first Android workspace with on-device AI, cloud models, reusable templates, and chat grounded in your prompt library.
QuadQR beyond JavaScript. A reusable Rust implementation with native bridges for Android and Flutter, plus an experimental WebAssembly adapter.
Files from here to there. A private, open-source sharing app that connects your devices over a local network, even without the internet.
Give a familiar square some character. An Android library for branded QR codes with custom patterns, finder shapes, logos, and backgrounds.
Jewelry, before the fitting. A browser-based try-on experience that tracks hands and positions 3D rings and bracelets on live video or uploaded images.
From vendor feeds to a usable catalog. Internal WordPress tools that normalize and synchronize more than one million diamond SKUs with WooCommerce.
Custom jewelry storefronts and product tools. WordPress and WooCommerce plugins, ring-building workflows, flexible product filters, and R&D into realistic 3D jewelry viewing.
02 / Behind the code
Hello, I’m Akansh. I like understanding how things work. Then asking how they could work differently.
I’m a software engineer working across backend systems, web applications, and Android. My own projects are where curiosity gets room to run — from simpler file sharing to an entirely different kind of matrix code.
I care about thoughtful software: useful in everyday life, clear in its purpose, and built with attention to the details.
