Software for businesses and individuals, straight from the developer
I build mobile apps, web systems and AI features, or automate repetitive manual work. I have been developing since 2015. I lived in Bolton, England, for ten years and worked for British and international companies. I work alone: whatever I take on, I build myself.
What I take on
I've worked in these areas for years, and I show earlier jobs for each. If I won't take a job on, I'll say so. Where I can, I'll still point you in a sensible direction.
I build apps for iOS and Android from one shared codebase. Where needed I also add device connections, face or fingerprint login and offline data.
I build customer portals, admin interfaces, reports and online shops. I make sure they run quickly and stay easy to fix later.
I plan how data is stored and who can see it, then connect the systems you need. I also write down how they exchange data.
I set up hosting so that the system can be updated and restored after a failure.
I help sharpen the idea, plan the build and decide how we will measure the result.
I build features on top of language models, and I write down how I checked them.
Work
A selection from my work since 2021. For each job I describe the task, my own role and the decisions I made. Where there are figures, I show the results too.
SafestWay · Founder Engineer
SafestWay shows the safest route, not the fastest one. To do that it works through millions of records on crime, street lighting and cameras.
When this could help you
If you have a lot of map data to process and want one developer who designs everything from the mobile app to the database, this is the work to look at.
Monument (UK digital bank), via Nearform · Product Platform Engineer
Five screens can be updated without releasing a new app version, and every release can be traced back.
When this could help you
If you want your team to change content or rules themselves, without booking a developer every week, this is how it can work.
Tether Data (QVAC programme) · AI Product and Cross-Platform Runtime Engineer
The same interface runs on desktop and mobile, in five different environments, even without internet. The tests I handed over can be run by the client themselves.
When this could help you
If customer data, or health or legal data, has to stay on the device, I know how to make AI run on it without a cloud.
Florio GmbH (a Sobi subsidiary, Munich) · AI-First Lead React Native Developer
The medical software handles patient data without internet and connects to Bluetooth smart injectors. Every release can be traced.
When this could help you
If your app connects to a measuring device, a gate, a printer or a sensor, I can also build the code on the phone that talks to it.
Credo Therapies · Lead Product Engineer – Mobile, AI UX & Delivery
I added personalised AI suggestions to a therapy app. I measured how fast they responded, and the cost of using them could be tracked.
When this could help you
If you want an AI feature, I will plan how we measure what it costs to run, how fast it responds and what people use it for.
ComAve · UI/UX Frontend Engineer
I made a Figma design, then a React/Next.js interface, and checked in the browser that it worked.
When this could help you
If you do not have an interface design yet, I can take on the design as well as the build.
Process
I put in writing what I promise, show you the finished work every week and invoice by phase. The source code is yours, and the domain and accounts are in your name.
Tell me what is not working or what you would like. You can email me or book the call. After a call I write up what we agreed.
I write down what I will build and how I will divide the work into stages. I explain the risks and what I need from you. If no discovery is needed, I send the itemised proposal after the free call. Otherwise, you receive it at the end of discovery, together with the written plan.
We write down what the work includes, what is left out, what is one-off and what is monthly. I invoice by the agreed stages and I do not ask for a large deposit.
Each week I show you what is finished, and you can try it yourself. If we change the plan, we put that in writing.
I hand over the source code in your own repository, with the documentation. The domain and accounts are in your name. You can ask me to run it for you, but you do not have to.
The first 30-minute call is free. Tell me when you're free and I'll reply with a time →
How I use AI
I use AI tools every day. The time I save lets me run more tests and review the work more closely.
What I put in writing
Prices
Here you can see what you get for a code review and for discovery, and what a first development phase starts at. For regulated data, device connections or a very large project, the free call is followed by paid discovery. Otherwise we decide on the call whether you need it. If you don't, I send you a final itemised price in writing afterwards. If you do, you get it at the end of discovery, together with a written plan. If you carry on with me, I credit the fee for the code review or discovery against the price of the next step.
These amounts are illustrative. The price list is not final yet.
In two working days I go through your system or app and recommend in writing what to do with it. The first 30-minute call is free.
You already have a system or an app, and you want to know what state it is in.
At the end you get the written material, and then you decide whether to continue. If we don't, the material is yours and you can take it to someone else. Net prices. VAT is not included.
You are planning something larger, or it is not yet clear exactly what needs building.
At the end you get the written material, and then you decide whether to continue. If we don't, the material is yours and you can take it to someone else. Net prices. VAT is not included.
You already know what you want and you want the first version in front of real users as soon as possible.
Net prices. VAT is not included.
If you're not sure which one fits, book a free 30-minute call and we'll work it out.
A deadline or a budget doesn't change the price of the same work. With a tight deadline fewer features fit, and with a tight budget I suggest a smaller first phase.
| Example | Time | Estimated price |
|---|---|---|
Field app for 40 technicians | 6–13 weeks | €9,600–22,700 |
Internal system instead of Excel | 6–15 weeks | €9,600–25,900 |
Automating manual admin | 2–4 weeks | €3,000–7,000 |
Health app with a device connection | 7–16 weeks | €11,400–28,500 Discovery needed: regulated sector, device connection |
These are illustrative estimates, worked out with the same fixed rules I use for every estimate. They are not proposals. To get one for your own project, book the free 30-minute call.
Billed in euros.
About
I have been writing software since 2015. I lived in Bolton, England, from 2016 to 2026 and worked for British and international companies, on site, hybrid and remote. I worked at Missguided and PrettyLittleThing. Through Nearform I built for a digital bank, and I took part in Tether's QVAC programme. I have also worked on medical software and on a live sports streaming platform. As SafestWay’s founding engineer, I am building an app that suggests safe routes for walking at night. I am now based in Kecskemét, Hungary, on CET, which overlaps the UK working day, and I take on work for British, Hungarian and other clients.

Questions
At an agency, the person you talk to is usually not the one who builds. Finding an experienced in-house developer can take months. With me you talk directly to the person doing the work. I look after the mobile app, the web interface, the back end and the hosting, and I am responsible for the result. If a job needs more people, I will tell you up front.
We work under a written contract and I invoice stage by stage. The code sits in your own repository, with documentation. If I will be out of reach, I tell you beforehand. Another developer can take the work over.
You do. The domain, hosting, App Store, Google Play and cloud accounts are in your name, and the source code is in your own repository.
Because I need to know the job exactly before I can give a final price. For a code review or discovery, I write down in advance what you get. The prices on this site are illustrations. For the first stage of a build I show a starting price, for other work an estimate, and I explain what moves the figure. The sample estimates follow the same fixed rules I use for every estimate. To get one for your own project, book the free call. If no discovery is needed, I give you the final itemised price in writing after that call. If it is needed, you get it at the end of discovery, together with the written plan.
Yes, every day. I put the time it saves into testing, review and documentation. I am still responsible for the decisions and for the finished work. The fee covers that work and that responsibility.
Yes. English has been my working language for ten years, in British and international teams, and I use it every day. Hungarian is my first language, so I work in that too. I do not claim to write like a native English speaker, but the documentation comes in plain English.
Yes, if the website is an important part of how your business runs. I design it around your business, plan how it looks and make sure it loads quickly. If a template site is enough, there are cheaper options, and I will say so.
Contact
The first 30-minute call is free. Tell me when you're free and I'll reply with a time. If you'd rather write, email me. I reply within one working day.
