    “New shop, more orders in the first week.”

    We had a template shop that looked like everyone else's. Dezső rebuilt it from scratch. Fast, clean, looks great on a phone. We sold more from the first week, and the work landed on time, no surprises.

    “Built an always-on scraper that does the lookup and the maths, and pushes the deals to Telegram”

    We were checking five auction sites with a spreadsheet at midnight and still missing the good lots. The studio built a system that watches the auctions for us, compares each car to the actual Hungarian used-car market with the import tax and shipping already in, and sends the real deals to our Telegram. We open the app from the message, the deal's already calculated. We've stopped guessing.

    “Internal automation tool for a print studio. Orders and invoicing now run themselves.”

    Order tracking, client approvals, invoicing. The things that ate my evenings. Dezső built one internal tool in a month and now they just happen. Nothing fancy on the surface, but I got my evenings back.

    “Built a radar that reads open-ended answers and tells the teacher which misconceptions are running the room”

    Our open-ended questions used to be the part of the assessment we'd skim, because reading 60 answers for a pattern was a whole evening. The team built a system that does the reading for us and tells us, per question, which misconception is running the room - and what to do about it, not just that it's there. We stopped over-prescribing 'more practice'. We started reteaching the right thing.

    “Automated video-editing pipeline. Three ready-to-post clips in the time it took to make one.”

    Raw footage goes in, ready-to-post clips come out. The system catches mistakes before anything goes public. I'm not editing less carefully, I'm just not doing the boring repeat work anymore.

    “Built an AI app that reads your watch data. It actually tells you when something's off, in plain everyday words”

    Our smartwatches were collecting data nobody actually read. The studio built a system that connects the dots, sleep + heart rate + activity together, and tells you in plain words what changed and why it matters. The week we started using it, it caught a pattern I'd missed for years. The team also handed back a manual so we can keep adding new sources without rebuilding everything.

    “Took an AI from demo to production. Now it serves real customers.”

    We had an AI that looked great in a demo but kept breaking with real users. Dezső took it through to a real product, with checks at every step so nothing odd reaches a customer. Nine weeks later, live traffic, no fires.

    “Built an AI 3D-tour generator for property listings. Photos go in, an explorable first-person walkthrough drops out in seconds”

    We honestly didn't think this was possible. Someone types in a property description, and a moment later there's a 3D model of the apartment that you can walk through in first person, like a video game. Our designers can still tweak it by hand, and within two weeks it was hooked into our listing site. Buyers actually call us back because of these tours.

Working software, shipped and documented. It's yours - code, accounts, the lot. We stay on if you want us.

// questions, answered

Straight answers to what people ask before starting a project.

What is DField Solutions?
DField Solutions is a Budapest-based custom software studio that designs, builds and runs production-grade software end to end - AI agents, web and mobile apps, web shops, blockchain and cybersecurity. One partner from idea to a running system you own, 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 across Hungary, the EU, and remotely worldwide - including the UK, US and 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 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.
is your big idea ready to go wild?

Let's buildyour thing.
