// what I build

I build custom, production-grade software end to end: I scope it, design it, build it and run it myself - AI agents, web and mobile apps, webshops, blockchain, backends and infrastructure, right down to the OS layer. Not templates, not slideware - real systems you own. Every line below is shipped work; open a project and see it run.

> AI & AGENTS

Models, chatbots and autonomous agents that do real work.

> BLOCKCHAIN / WEB3

Smart contracts, tokens and on-chain apps - audited and shipped.

> TELEGRAM & BOTS

Bots and automations that run the business while you sleep.

> WEBSITES & WEB APPS

Fast, beautiful sites and full web platforms.

> WEBSHOPS & PAYMENTS

Online stores with real checkout, payments and inventory.

> BACKEND & SERVERS

APIs, databases and pipelines - the engine behind the app.

> MOBILE APPS

iOS & Android from one codebase, app-store ready.

> SECURITY & SYSTEMS

Pentests, exploit research and hardening - down to the OS.

// how it works

01

Tell me the problem

In plain words. No tech jargon, no spec document required. A friendly conversation is enough to start.

02

I design & build it

I scope it, design it, and build it - you watch real progress from the person writing the code, not slideware and promises.

03

You own the result

Working software, shipped and documented. It's yours - code, accounts, the lot. And I stick around if you want me to.

// questions, answered

Straight answers to what people ask before starting a project.

Who is behind DField?
Me - Dezső Mező, a Budapest-based software engineer. I design, build and run production-grade software end to end, myself - AI agents, web and mobile apps, web shops, blockchain and cybersecurity. One person from idea to a running system you own, no juniors learning on your budget, in English or Hungarian.
What does DField Solutions build?
Custom software across six areas: AI (chatbots, RAG search, autonomous agents), websites and web shops, mobile apps, blockchain and smart contracts, cybersecurity audits, and bespoke backends and SaaS. Real systems you own, not templates or slideware.
Where are you based, and who do you work with?
We're based in Budapest, Hungary, and deliver all over the world. We have shipped work in Hungary, Germany, Austria, the Netherlands, the United Kingdom, France, Italy, Spain, Malta, the United States, Mexico and the UAE. Every project runs in English or Hungarian.
How does a project start, and how fast?
It starts with a free 30-minute intro call. You describe the problem in plain words; we scope it, send a written estimate with a timeline, and usually ship a working prototype within the first two weeks.
How much does a project cost?
It depends on scope. A focused project starts around EUR 2,000; enterprise-scale work runs EUR 15-30k. You get a fixed written estimate with scope and timeline after the intro call - no surprises.
Can I try DField's products before buying?
Yes, right on this page. Every product has a live demo running in the browser: autoszoftver's deal feed and margin calculator, JuriSafe's sourced legal Q&A, SimulSpeak's real-time voice translation, the UseAIEasily support agent, a shift-cost planner for alkalmimunkaero and a stay finder for legjobbnyaralasok. They return real output, not scripted mockups, and each product has a free way in - free tiers or no-registration trials.
Which product fits a clinic, law firm or accounting office?
Clinics and practices: UseAIEasily handles bookings and patient questions on chat, email and phone, self-hosted so data stays yours. Law and accounting firms: JuriSafe answers with the exact statute cited and drafts contracts or NDAs. Car dealers: autoszoftver prices EU imports before you bid. Anything custom on top, I build to order.
Can you build private AI that doesn't leak our data?
Yes - AI is a core practice. We build private, EU-hosted assistants that answer only from your own documents, plus RAG search, workflow automation and multi-agent systems, engineered so they don't leak data or hallucinate.
Does DField do original AI research?
Yes. Dezső Mező has published three openly-licensed AI papers on Zenodo (CC BY 4.0): two co-authored with Noaber AI, on agent safety (The Hardened Shell) and on self-adapting language models (Fewer, Better Self-Edits), plus a solo practitioner report on optimizing production retrieval (RAG) for accuracy, speed and cost at once. The AI we ship is grounded in research, not hype.

When you write, it's me who answers. No sales team, no account managers, no runaround. Tell me what you're trying to build and I'll tell you honestly what it takes.
