    “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.

    “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.

    “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.

    “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.

    “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.

    “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”

    “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.

    “Or one Ethereum tx with NFT proof”

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.
