A platform for divers: dive log, live depth and vitals, marine-life tracking. On the team I own the web app, the backend and the store releases.
See it on the App StoreApps that actually ship.
I build mobile apps, websites and e-shops for businesses, and take them all the way to the App Store, Google Play and the web.
Things running today
From apps for divers to museum ticket desks, built together with their teams. Where a client prefers not to be named, I describe what the app does.

Every vehicle in and out is reported to the Greek tax authority (AADE), even with no signal. The camera reads the number plate.App + server · Flutter, Laravel

From idea to launch
Mobile apps
iOS & Android from one codebase, including publishing to the stores and keeping them updated.
Websites & e-shops
Fast pages that work properly on phones and help customers buy from you or find you.
Whole products
App, web and server designed together so they talk to each other, and to AADE where needed.
Project rescue
Is your project stuck? I take it over, find what's wrong and get it live.
What happens after you write
- 1
Talk
You tell me what you want in your own words. I ask until it's clear what's needed and what isn't.
- 2
Proposal
I send you in writing what will be built, what it costs and when it will be ready, before we start.
- 3
Build
You follow progress on a test version on your own phone and give feedback while it's being built.
- 4
Launch
I publish it to the App Store, Google Play or the web, and stay around for fixes and updates.
Got an idea in mind?
It doesn't need to be finished. Two lines are enough to start.
Frequently asked
How much does it cost?
It depends on what we build. A website and an app with a server are very different projects. After our first talk I send a written proposal with cost and timeline.
How long does it take?
A website usually takes a few weeks, an app with a server a few months. The dates go in the proposal.
Who owns the app?
You do. The app is published under your business's developer account and the code is handed over to you.
Can I change texts and products myself?
Yes, if you need to. I build a simple admin so you can change prices, photos and texts without calling me.
What happens after launch?
We can continue with maintenance: updates for new iOS and Android versions, fixes and small changes.
I already have an app that got stuck. Can you help?
Yes. Send me what exists: code, store access and whatever was handed over. I review it and tell you what it takes to get it live.
What should we build?
Write a few words about your business and your idea. No technical terms needed.
