Two co-authored, openly-licensed papers. I don't just use AI, I research it.
Research paperZenodo · CC BY 4.0
Fewer, Better Self-Edits
Self-edits and distillation in Self-Adapting LLMs (SEAL)
Co-authored research on Self-Adapting Language Models (SEAL), where a model writes its own training data and folds it into its own weights via LoRA. We show a single well-chosen self-edit matches SEAL's union-of-five using a fifth of the data, and that KL-distillation from a frozen teacher cuts prior-knowledge loss roughly 4x at equal injection. With Joran van Beek of Noaber AI.
Read the paper →Research paperZenodo · CC BY 4.0The Hardened Shell
Safety & sovereignty in the OpenClaw agent architecture
Co-authored research on the "Agentic Paradox" — how autonomous agents inherit outdated trust assumptions once they read private data, run shell commands and keep memory — and what hardens them against prompt injection. With Joran van Beek of Noaber AI.

Fewer, Better Self-Edits: How Many Self-Edits and Which Loss in Self-Adapting Language Models
Co-authored research on Self-Adapting Language Models (SEAL), where a model writes its own training data and folds it into its own weights via LoRA. We show a single well-chosen self-edit matches SEAL's union-of-five using a fifth of the data, and that KL-distillation from a frozen teacher cuts prior-knowledge loss roughly 4x at equal injection. With Joran van Beek of Noaber AI.

The Hardened Shell: Evaluating Safety and Sovereignty in the OpenClaw Agent Architecture
Co-authored research on the "Agentic Paradox" — how autonomous agents inherit outdated trust assumptions once they read private data, run shell commands and keep memory — and what hardens them against prompt injection. With Joran van Beek of Noaber AI.

Two Android phones rooted. One car-tablet won.
A hands-on reverse-engineering teardown: what it actually takes to break into locked-down hardware, and why the difference came down to the device, not the skill.

// 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.

// 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.
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.
