United Kingdom
Detartech is a software company whose Istanbul team delivers web platforms, AI integration and DevOps for companies across the United Kingdom. The working language is English, Istanbul is three hours ahead in winter and two in summer, and systems that process personal data are designed with the UK GDPR and the Data Protection Act 2018 in mind. World Summer Schools, the platform we built from scratch for BYA Consultancy, is featured on this page.
We built World Summer Schools from scratch with Next.js and .NET, bringing hundreds of programmes into one catalogue that can be filtered by age, country and dates. We decide on the rendering strategy, multilingual architecture and content management up front. Documentation and handover documents are in English.
View serviceAt World Summer Schools an OpenAI integration turns the raw data entered by content managers into summary and category suggestions. In an AI integration we define up front what data goes to the model, how accuracy is measured and where the data boundary sits under the UK GDPR.
View serviceFor World Summer Schools we set up CI/CD automation with Jenkins and a scalable Ubuntu-based infrastructure. We design the pipeline less for fast releases and more for safe rollbacks. Environment and secret management, observability and a written handover are included.
View serviceFor a UK start-up, the scope of the first version, the question to validate and the acceptance criteria are written in English. Meetings are planned to fall in the UK morning; progress is visible on a test environment, and the code and accounts remain yours.
View serviceBefore a product built with Lovable, Replit or Codex goes live, it passes through an audit, fixes and a CI/CD security gate. Holes close to personal data covered by the UK GDPR come first; the audit usually takes three to five business days.
View serviceWe build iOS and Android apps from one team with Flutter or React Native, and publish to the App Store and Google Play through your own accounts. Documentation and release notes are prepared in English.
View serviceOn a site targeting the UK, mapping English versions to the right market with hreflang, indexing and Core Web Vitals are handled together. If there is a migration, a 301 map is prepared; we do not guarantee rankings.
View serviceAI engines answering English questions pick their sources from a very large pool; whether your site is readable in that choice depends on structured data, E-E-A-T signals and an llms.txt file. We build that preparation; we do not guarantee being quoted.
View serviceEnquiries from Meta Lead Ads, LinkedIn forms and site forms flow into the CRM through one line, and the sales outcome returns to the ad platform through the Conversions API. Because lead data stays on your server, documenting its route under the UK GDPR is simpler.
View serviceFor a company preparing for a funding round, we put questions such as account and domain ownership, open-source licences, which country the data sits in and the UK GDPR position in writing before the round opens. We sit in the technical part of hiring interviews and leave the decision to you.
View serviceIf your traffic peaks during UK working hours, we find the bottleneck with measurements taken in those hours. Database and query optimisation, cache layers and queues are applied with a migration plan that can be rolled back.
View serviceIstanbul uses UTC+3 all year. The United Kingdom is on GMT (UTC+0) in winter and BST (UTC+1) in summer, so Istanbul is three hours ahead in winter and two hours ahead in summer. A 09:00 start in the UK is 12:00 or 11:00 in Istanbul. Shared working hours fall in the UK morning and the first half of the afternoon, and that is where we schedule daily meetings.
The process is designed for remote collaboration: a discovery meeting online or in person, a written architecture proposal and project plan, two-week sprints and a working demo at the end of each sprint. Progress is tracked on a Jira or Linear board, there is a weekly status meeting, and a direct Slack channel stays open for urgent matters.
For UK clients, meetings, sprint reports, technical documentation and handover documents are all in English. Our project management and documentation already run in Turkish and English, so this needs no special setup. If your product will publish in other languages too, the multilingual architecture is built in from the start.
After leaving the EU, the United Kingdom carried the GDPR into its own law as the UK GDPR, which applies alongside the Data Protection Act 2018. On the software side this framework turns into concrete architecture decisions:
The legal assessment is settled with your adviser; we make sure those decisions are implemented correctly in the code and the infrastructure. On the Turkish side, where our team works, KVKK applies.
BYA Consultancy wanted to connect families and students with summer school programmes around the world. The existing process relied on manual content management, email correspondence and scattered information sources. World Summer Schools, which we built from scratch, answers that need:
At World Summer Schools, AI is used to speed up content entry: the model produces summaries and category suggestions, and content managers work with those suggestions. In a similar integration we first decide which data is sent to the model, which data stays inside the system and how the accuracy of the output will be measured. Where personal data is involved, that boundary is designed together with UK GDPR requirements.
On delivery, full ownership of the source code passes to you, and the transfer is written explicitly into the contract. Thirty days of post-launch support are included, after which monthly maintenance packages are available. For pricing you choose between a fixed-price and a time and materials model, and the proposal is sent in writing after the discovery call.
Wherever you are, the first meeting is free, online or in person.
