CodeHorizon is a one-person software studio. I make Chrome extensions, Android apps and websites that do one job really well, keep your data on your device, and keep getting better after launch.
Each one started as something that annoyed me. All six are live and you can use them today. (the previews move, too)
01 / 06Chrome extension + web
ShopGrade
A one-click audit for any Shopify store.
It checks performance, mobile usability, trust, buying friction and SEO, then turns what it finds into a prioritised report that an agency can hand straight to a client.
It looks like a calculator. It's actually a vault.
Enter your PIN and press equals, and the calculator opens an encrypted vault. The keys stay in the Android Keystore and your fingerprint unlocks it. Nobody picking up your phone would know it's there.
Small steps taken every day will carry you further than a big leap taken once.
Companion AI
04 / 06Chrome extension
TubeFocus
YouTube, without the rabbit hole.
It hides recommendations, Shorts and anything else designed to keep you scrolling, and you choose what stays. The built-in focus timer keeps counting even when Chrome puts the extension to sleep.
Highlight any text on the web and pin a note to it. The notes are anchored to the exact words, so they line up when you come back, and you can search, sort and export them.
Good research is mostly remembering what mattered. Anchoring notes to exact text ranges means they are there when you come back, even after the page changes.

02 / How it's made
From itch to app store.
My own products and client projects follow the same road. It's rarely a straight line, which is how it should be.
01
Feel the itch
It starts with real friction, like forty lost tabs or an audit spread across five tools.
02
Sketch and prototype
I design in Figma, build fast, and use it every day until it feels right.
03
Ship it properly
That means store review, CI/CD, a real product page, and no loose ends.
04
Keep caring
I keep sending updates and fixes and keep up with platform changes. Launch day is where the work really starts.
03 / Services
What I can build for you.
I give client work the same care as my own products, from Figma to a live release, and I stay around afterwards. Everything below is something I have already shipped.
01
Websites
Fast, responsive sites and web apps in React and Next.js, designed in Figma, with CI/CD and edge hosting set up from day one.
CodeHorizon started with a simple itch. I kept running into small, annoying problems: forty tabs I couldn't find, a YouTube feed built to eat my evenings, and a store audit spread across five different tools. So I built the fixes myself, then shipped them so anyone could use them.
I care about the small stuff: an animation that feels right, an app that works offline, and data that never leaves your phone. I also have hands-on e-commerce experience, so I know how much a slow page or a clumsy checkout really costs.
Everything here is designed, built and looked after by one person. When you write in, you're talking to the person who made it.
