Software Development for Hungary, With AI Agents Under Review

A team in Hungary working with Ankara loses less of the day than expected: Ankara is two hours ahead in winter and one hour ahead in summer, so 7 or 8 hours of a standard working day overlap. The harder question sits in the contract. Engineers in Türkiye who can open systems holding your users' personal data are in most set-ups receiving a GDPR transfer, and national rules add a data protection act and a supervisory authority, NAIH.

Curiosive is a studio in Ankara, Türkiye, building with AI coding agents under senior engineer review. We build a product end to end or join as an embedded partner on a monthly engagement. Agents do the volume: scaffolding, migrations, test coverage and refactors across hundreds of files. Engineers design data models, authentication and permissions, and read every change before it merges. The code is yours from the first commit.

Hungary supplements the GDPR with Act CXII of 2011 on the right to informational self-determination and on the freedom of information, and its supervisory authority is the Nemzeti Adatvédelmi és Információszabadság Hatóság (NAIH), which runs a dedicated online portal for controllers to notify personal data breaches. As of 2 October 2026, Türkiye is not on the European Commission's adequacy list. EDPB Guidelines 05/2021 treat remote access from a third country as a transfer when the three transfer criteria are met, even if data is only displayed on a screen for support. That calls for another Chapter V tool, such as the Standard Contractual Clauses in Implementing Decision (EU) 2021/914; if you are the controller and the studio acts as your processor, that is the controller to processor module. Under Clause 14 both parties warrant they have no reason to believe the destination country's laws and practices prevent the importer from complying. It is worth confirming the module and annexes with your lawyer.

Shared working hours between Hungary and Ankara, winter and summer

Ankara is on UTC+3 all year because Türkiye does not use daylight saving time, while Hungary moves between UTC+1 and UTC+2. In winter Ankara is two hours ahead. Our 09:00 start is 07:00 in Hungary, our 18:00 finish is 16:00, and your 09:00 is 11:00 in Ankara, which leaves 7 shared hours in a standard 09:00 to 18:00 day. In summer the gap narrows to one hour: our day runs from 08:00 to 17:00 Hungarian time, your 09:00 is 10:00 for us, and 8 hours overlap. Work runs on Türkiye business hours, so a question sent after 16:00 your time in winter, or after 17:00 in summer, waits for our next morning. Decisions are written down, a releasable increment ships every week and one short weekly call covers the rest.

Software that reports receipt data to NAV in Hungary from 2026

One recent change lands directly in the codebase of any system that issues receipts. Since 1 September 2026, businesses that issue manual or computer-generated receipts must report receipt data to NAV, the National Tax and Customs Administration, within three calendar days of issue, totalled per day and split by VAT rate. The routes are a cash register app such as NAV's free ePénztárgép, manual entry on the KOBAK portal, or a machine-to-machine interface from your own systems, which NAV suggests for larger businesses, webshops and other online sellers and service providers. NAV said it will not fine businesses from 1 September to 31 December 2026, and fines for faulty or missing reporting may apply from 1 January 2027. Engineers design the daily aggregation and the reconciliation against sales records; agents write the client, retries and test fixtures around it.

How the agentic engineering loop runs on your codebase

Each piece of work starts as a written task: acceptance criteria, plus the files and decisions the agent is not allowed to touch. Claude Code or Cursor works inside your repository, reads the surrounding code, plans, implements and updates tests, then runs the type checker, linter and test suite before it proposes anything. A senior engineer reads the diff. Agents never merge their own work, and continuous integration repeats the checks. This makes repetitive engineering cheaper, but it does not make review optional: the more code an agent writes, the more the reviewer matters. Data models, authorization, payment paths and anything touching personal data stay with engineers. Work at scale is familiar ground: we rebuilt Zing Coach (zing.coach), AI fitness coaching for more than a million users, in full from Webflow to Next.js for a client in the United States.

Contracts, currency and supplier security for companies in Hungary

Hungarian companies contract with Curiosive cross-border. The country is outside the euro area and uses the forint, while our published prices are US dollar starting points, so the invoicing currency is something to agree in the written scope. Work runs as AI-accelerated development, starting from $2,000 per month, with scope agreed in writing. If your company is a medium-sized or larger entity in a NIS2 sector, such as cloud computing or managed services, Article 21 asks you to address supply chain security with direct suppliers and service providers, so expect to document supplier access. Every change we make is read for secrets handling, input validation, access control and dependency risk. We maintained the Detailed SEO Extension, used by 600,000 SEOs, for a UK client through its acquisition by Ahrefs.

Questions

The things people ask before starting.

Can a Hungarian company outsource software development to Türkiye under GDPR?

Yes, with a GDPR Chapter V transfer tool in place. Türkiye has no EU adequacy decision as of 2 October 2026, so a tool such as the Standard Contractual Clauses in Decision (EU) 2021/914 is needed. Remote access to personal data can itself be a transfer, so put the clauses in place before engineers get production credentials.

How many working hours overlap between Hungary and Ankara?

Seven hours in winter and eight in summer, out of a standard 09:00 to 18:00 day. Ankara stays on UTC+3 while Hungary switches between UTC+1 and UTC+2, so a call at 09:00 your time is 11:00 for us in winter and 10:00 in summer.

What does a software development monthly engagement cost for a team in Hungary?

Work runs as AI-accelerated development, starting from $2,000 per month, with scope agreed in writing. Both are published starting points in US dollars, not quotes, and the figure for your project follows a discovery call.

Who owns the code AI agents write for a Hungarian client?

You do, from the first commit. Repository, database and hosting accounts are opened in your name or connected to accounts you already hold. The code is typed, tested and documented, and nothing in it ties you to the coding agents or other tooling we use.
