One team. Production code in 14 days. Security audit on every build.

From the founder

Why we built the studio. In four minutes.

Dezső on how a 30-minute call becomes production code in week two.

Excellence shipped. That's why they stay.

Same bar on every project · regardless of brief size or NDA. Named and NDA clients both rate us five.

5.0 / 5

One bar. One quality. Every project.

    HU

    Our webshop went from 'looks like everyone else' to ours.

    We had a template shop that nobody could tell apart from the next ten. Dezső redesigned it from scratch · animated, fast, looks great on a phone. We were selling more in the first week. Calm communication, on time, no surprises.

    AI-correlated lifestyle plan by Friday

    AIHealthIQ went from a wearable-data dump to a coherent recommender in one engagement · the correlation engine is what we couldn't build in-house. The team handed back the runbook and the ingest can be extended without re-architecting the AI layer.

    The boring back-office work finally runs without me.

    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.

    Walkable 3D in seconds

    We needed walkable 3D from prose specs, with a manual escape hatch for designers. The studio shipped both, plus the API · listing portal integration came in under two weeks once the pipeline was stable.

    I used to edit one video. Now I ship three in the same time.

    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.

    Site, courses, contact in one flow

    We needed a credible-looking site fast for the AI-security launch · the studio shipped on time, the brand reads exactly as we discussed, and inbound calls started within the first week.

    We had AI that worked in demos. Now it works for paying customers.

    Our AI sat in notebooks · brilliant, fragile, never quite ready for real users. Dezső took it through to production · with checks at every step so nothing weird reaches a customer. Nine weeks later, real traffic, no fires.

    One quiet dashboard in

    We came in with an email + spreadsheet workflow and a hundred edge cases. The studio scoped it down to four pipeline states · the creators stopped asking 'what's the status' on day one of the rollout.

    AnonymousAnonymousNorth Star Creator

    My launch site felt like a real label was behind it.

    I wanted something that didn't look like a 'musician's homepage'. The site loads instantly, it works on a phone, and we measured the streaming numbers actually go up after we shared it. Two weeks from kickoff to live.

    Get a private chatbot, on your server, in 5 minutes

    We had a hard GDPR constraint and a 6-week deadline. The chatbot stack landed on the customer's box, end-to-end, in week 5 · the embed snippet went live on day 38 with zero data leaving their server.

    AI-tailored ones land · and teach

    We needed a phishing-sim platform that does the NIS2 paperwork as a side-effect of running the campaigns. PhisGuard does · CISO export went straight to the auditor without a manual rewrite.

    MCP Security checks intent · then decides

    We had AI agents calling production tools and no good story for the auditor. MCP Security gave us one layer · the audit log + YAML policy passed regulator review on the first round.

    Get a ready-to-import n8n JSON in 2 minutes

    Our PMs were asking devs to build n8n flows for them. Now the PMs ship the JSON in chat and we just review the diff · saved roughly two engineering hours per workflow.

    Or read one feed that scores them all

    We wanted a news product that doesn't pretend bias doesn't exist. The studio shipped the score engine and the diff view together · readers actually click the bias ribbon to see why a piece scores how it does.

    Four agents · cross-checked decisions

    We tried single-bot strategies and got chopped on the next news cycle. The quorum approach hasn't eliminated drawdowns, but it eliminated the catastrophic drawdowns · which is what we needed.

    Math, not gut feel

    We were copy-pasting odds across four tabs and screwing up parlays in Excel. BetEdge collapses that into one screen with the rationale visible · the only thing left to do is decide whether to place.

    Or one Ethereum tx with NFT proof

    We needed a marketplace that an external auditor could actually sign · the studio shipped the contracts, the indexer, and the threat-model document together so audit prep was a week, not a month.

    One character's journey, end to end

    We wanted something nobody else in the market had. The studio shipped a scroll-bound narrative the brand still uses two years on · we never replaced it because nothing local came close.

    Solana NFT tickets · QR check-in

    We had a forged-ticket problem at the door of every event. The Solana program ended that conversation · scanner says spent or fake, no debate.

    Animated table · real-time sync · mobile-OK

    Browser poker products usually feel like a spreadsheet. This one doesn't · the animation budget is right and the sync is stable across mobile + desktop seats.

    GlowUp · 2-minute mornings, every day

    We'd been through two self-improvement app builds that died in store review. The studio shipped this one through review on the first attempt and the streak engine actually keeps users · the 2-minute floor was the right call.

    SYSTEM shell · 4 seconds

    We'd had a 'firewall closes everything' policy and a forgotten PaperCut server. The PoC walked SOC through the actual blast radius in four seconds · the patch + segmentation conversation finally landed.

    Audit

    Security check before every launch

    Real-world security testing runs before anything goes live. Not a separate invoice you forgot to ask for.

Why one engagement, not three vendors

Website agency + automation consultant + security firm = €20,000–60,000, three timelines, three invoices, and nobody accountable for the whole thing. The 8-week program delivers all of it under one contract at a fraction of the combined cost.

08FAQ/ 09
FAQ

Common questions, direct answers.

Most of these we've been asked already · if yours isn't here, email us.

  • DField Solutions is a Budapest-based engineering studio that ships production-grade AI, web, mobile, blockchain and cybersecurity work for SaaS, fintech and e-commerce teams across the EU. Founded 2023 by Dezső Mező, an ex-fintech CTO. Senior engineers only · no junior subcontracting on your project.
  • Code shipped to production. AI agents with eval harnesses, RAG pipelines on Hungarian or English content, smart-contract audits with fix-PRs, multi-tenant SaaS on Postgres with FORCE RLS, iOS / Android apps ready for store submission, NIS2 / SOC2 / AI Act readiness packs. Every engagement ends with something running, not a deck.
  • Yes · /pricing has the three tiers: fixed-price audit from €4 000, build sprints from €15 000, embedded retainer from €9 000/month. Net-30 invoicing in EUR / HUF / USD. EU B2B reverse-charge VAT. New clients pay 50% upfront; repeat work runs on net-30 only.
  • Two weeks. Our smallest engagement is the 14-day audit · you get a clickable prototype, a written report, and concrete fix-PRs against your repo by the end of week two. Build sprints run 4-12 weeks with fortnightly demos, so you see real output every two weeks regardless of sprint length.
  • Agencies sell hours and rotate juniors through your codebase; freelancers can't carry the full stack from AI down to compliance paperwork. We do both: production engineering across every layer, with the security review baked in (most agencies bolt it on at the end, most freelancers skip it). And we only do senior · the founder still ships code on every engagement.
  • Budapest, Hungary. We deliver across the EU (Vienna, Berlin, Amsterdam, London) plus remote-EU engagements. Daily client communication in English or Hungarian; the codebase and docs are always in English so the work travels with you. Time-zones up to GMT-5 work fine async with one weekly sync.
  • We write the code. No outsourcing, no sub-contractor chain, no offshore sweatshop. The team that scopes the engagement is the same team that ships the PRs · and the founder reviews every release. You can verify on /authors and /uses · no ghost-team trick.
  • Yes. Every engagement carries a documentation pack: GDPR DPA, AI Act risk classification (when AI is in scope), NIS2 readiness checklist, SOC2 / ISO 27001 alignment notes. Data stays in the EU, processed by a Hungarian EU member state. We've shipped this on fintech, SaaS and Web3 projects · we don't subcontract the compliance work to a separate auditor.
  • Yes. Visit /case-studies for shipped work with named clients (where NDA permits), measurable outcomes, and before / after numbers. /projects shows live URLs you can click through.
  • Yes. Send your template (we sign yours if the contents are standard) or use ours. We can also sign before scoping discussions if your project is sensitive.
