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.

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.
