The proprietor

MeetDezso

AI and GenAI engineer, Purple Team security, full-stack EVM and Solana, and the person who 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 you get when you hire the studio

You talk to the engineer: No account manager, no offshore hand-off. The person on the call is the person writing the code, so decisions take minutes and nothing is lost in translation.
Quick wins in the first two weeks: Speed fixes, the first automation, the security basics — live before the engagement is half done, so you see it working rather than hearing about it.
You own everything: Source, credentials, documentation, the n8n instance — handed over at the end. No lock-in, no retainer you did not ask for.
Built AI-native and AI-secure: The same person who builds the agent also breaks it: prompt-injection testing, tool-permission review and an audit log are part of the build, not an add-on.

What clients say

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

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

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.
Outcome: Got his evenings back

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.
Outcome: 3× as many videos out the door

Live in two weeks. Looks like a label is behind me.
I wanted something that didn't look like a typical 'musician's homepage'. The site loads instantly, works on a phone, and the streaming numbers actually went up after we shared it. Two weeks from kickoff to live.
Outcome: Live in 2 weeks · streaming numbers up
