What does DField Solutions do?

We build custom software end to end: AI automation, cybersecurity, blockchain, full-stack web and mobile, generative AI pipelines and web performance work. Most projects use two or three of those at once rather than one in isolation.

Who will I actually be working with?

Dezso Mezo, who runs the studio, and who is also the person who answers the phone. There is no account manager between you and the person building the thing.

Where are you based, and do you work remotely?

The studio is in Dunakeszi, just north of Budapest, Hungary. Clients are anywhere: the work is remote by default and we work in English, Hungarian and German.

How long does a project take?

The standard engagement is eight weeks. Weeks 1 to 2 are discovery, audit and quick wins already deployed. Weeks 3 to 5 build out the site and the AI workflows. Weeks 6 to 7 are security hardening and integrations. Week 8 is documentation, training and handover.

How does it start, and what does the first conversation cost?

A free 30-minute intro call. No obligation and no sales pressure. Describe the problem in plain words — you do not need a written specification to book it.

What we build

Six things we do well. Most projects use two or three of them at once.

AI automationThe repetitive half of your week, handed to software that does not get bored. Inbox triage, follow-ups, reporting, data entry between tools that were never meant to talk.Click to explore

CybersecurityPurple Team: the same person writes the exploit and closes the hole. Most agencies only harden, which means hardening against a threat nobody tested.Click to explore

BlockchainSolidity on Ethereum, Polygon, Base and Arbitrum. Anchor programs on Solana. Written with tests first, because a redeploy is not a hotfix once value is on the line.Click to explore

Full-stackIf you can describe it, we can build it. React and Next.js on the front, Python or Node behind, Postgres underneath, shipped to somewhere you can afford to run.Click to explore

Generative AIStable Diffusion and ComfyUI wired into the place where your content actually gets made, with a model fine-tuned so everything comes out looking like you.Click to explore

Web performanceA rebuild that loads on a phone on mobile data, in the country your customers are actually in. Core Web Vitals are the measurement, revenue is the point.Click to explore

About

The person you talk to

No account manager between you and the engineer. Dezső scopes it, builds it and answers the phone.

Dezso Mezo runs DField Solutions from Dunakeszi, just north of Budapest, and works with clients anywhere. He builds with PyTorch, LangChain and MCP on the AI side, Solidity and Anchor on chain, and Next.js, FastAPI and Postgres for everything else.

Purple Team means he runs the attack and then closes the gap. Most agencies only do one half.

He likes shipping, the occasional CTF, and starting things.

What clients say

From LinkedIn DM to live site. Two tiny tweaks, then shipped.
I found Dezső on LinkedIn, sent over a short brief, and what landed in my inbox was straight off the bat exactly the site I had pictured. We made two very minor changes and shipped it. No long calls, no decks, no waiting on revisions. Honestly the cleanest hand-off I have ever had with a developer.
Outcome: Cleanest developer hand-off he has had
Michael J Ringer
Founder · Vilya Protection
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.
Outcome: More buyers from the same traffic
Müller Márk
Managing Director · GeekCorner
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.
Outcome: AI in front of real customers
