WhatsApp Floating Button

Let customers reach you on WhatsApp in one tap — from any Shopify storefront

The problem

Shopify merchants in emerging markets rely on WhatsApp for customer support and sales. There was no native way to add a WhatsApp button to a storefront without custom code or bloated apps that tracked customer data.

The solution

A lightweight Shopify theme extension that injects a floating WhatsApp button. One tap opens WhatsApp with a pre-filled message — zero middleware, zero tracking, zero customer data stored. Free tier + Starter paid plan.

Female Fitness Finder

A verified directory connecting women with safe, women-only fitness spaces across the UK

The problem

Women looking for safe, women-only gyms and fitness classes had no centralised platform to discover and verify such spaces in the UK. Existing directories were generic and unverified.

The solution

A full-stack directory platform with location-based search, verified facility listings, gym owner registration, and a personal trainer directory — built for trust and ease of use on all devices.

MatrixInn PiP

One-click Picture-in-Picture for every video on every website

The problem

Switching browser tabs kills your video. Chrome's built-in PiP is buried in right-click menus and blocked on Netflix and Disney+. Users had to install heavy extensions or use workarounds.

The solution

A Manifest V3 extension that adds a hover PiP button to every video. Removes the disablePictureInPicture restriction on streaming platforms. Auto-PiP and keyboard shortcut included.

Privacy for WhatsApp

Blur your chats, contacts, and media in WhatsApp Web — one toggle

The problem

Using WhatsApp Web in public exposes your messages, contacts, and media to anyone nearby. No native privacy mode exists, and turning a laptop screen away is not always practical.

The solution

A Chrome extension that blurs all sensitive content in WhatsApp Web with a single shortcut. Per-feature controls, hover-to-reveal for selected elements, and an auto-blur mode when the mouse leaves the window.
