WHY US
What we ship · why it's different.
Production-grade AI, web, mobile and security from one team · with a hard deadline, a concrete deliverable, and a real invoice.
PROTOTYPE01
14 daysWorking code at the end of week two
Our two-week audit / build engagements end with something you can click through · a working prototype, fix-PRs, or both. Not a deck, not a mockup.
ENGINEER02
SeniorSenior-only · no junior subcontracting
Founder is an ex-fintech CTO. Everyone on the team has shipped multi-year production systems · no apprenticing on your project.
COMPLIANCE03
EUGDPR + AI Act + NIS2 paperwork on every engagement
Data stays in the EU, invoiced from a Hungarian EU member state via SEPA. We carry the regulatory pack so you don't have to.
ON EVERY BUILD04
AuditSecurity review baked into every shipment
Pentest + threat-model isn't an optional add-on · it runs before every production release. You don't outsource the security work to a separate lab.

Six disciplines · six concrete outcomes.
Not a feature list · measurable shipments. Every engagement ends with something running. The list below is what we typically hand over.

“Full webshop redesign · conversion went up.”
Redesigned the GeekCorner webshop from scratch · custom design, animated, mobile-first. Measurable conversion lift within the first week. Clean communication, delivered on time.
(02)Mexico
“Our workflow finally runs on itself.”
Dezső built us a tight internal tool in a month · order tracking, client approvals, invoicing. Nothing flashy, just work that stops needing a human.
(03)Budapest
“The AI pipeline keeps up with us now.”
Raw edits in, publish-ready clips out. Evals sit between every stage so nothing junky goes live. Saved me hours per day.
(04)International
“Production AI, not a demo.”
They pulled our agent stack out of notebook-hell, put it behind evals, and added real observability. Nine weeks later, live traffic.
(05)Hungary
“The launch site looked like a label built it.”
Next.js landing with streaming widgets, a fan form, and analytics. 98 on PageSpeed out of the box, and we measured the streams actually climbing.

Five main services, each broken down into concrete things. If the exact thing you need is on the list · that's what we do. If it's not, ask anyway · chances are we still handle it.

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.
