Detartech is a software company whose Istanbul team develops the digital signature and business process platform of Tegoly, a company based in Witten in the Ruhr area. We added new screens and modules to a live product, improved page load times on Azure and increased its search engine visibility. Meetings with companies in Witten are held in English and can be online or in person.
We added digital signature, document management and integration modules to Tegoly's live platform without disrupting existing users. On an inherited web product we review the code and architecture first, then move in small steps that can be rolled back.
View serviceAt Tegoly we improved page load times by working on the cache layer and server configuration. We start performance work not by adding servers but by measuring where the slowness comes from.
View serviceAt Tegoly we increased visibility through meta descriptions, content and technical SEO changes. For a product that sells into several markets, which page should appear for which search has to be planned. We do not promise rankings.
View serviceOur work with Tegoly was on an existing product; for a Witten company that wants to start a product from scratch, the process runs differently. The question to validate is written down, the scope is limited to it, and a working version can be seen on a test environment every two weeks.
View serviceFeatures added quickly with Cursor or Claude Code to a platform with live users carry extra risk. The audit checks access control, secrets, dependencies and input validation one by one, and findings are closed with small pull requests that do not break the live system.
View serviceWhen a web-based platform needs a mobile app, we can build an iOS and Android client with Flutter or React Native without rewriting the existing .NET services. Store release and version compatibility are planned from the start, and meetings run in English.
View serviceIn areas like digital signatures and document management, AI can speed up repetitive work such as classifying and summarising documents. In such an integration we limit the data sent to the model under the GDPR and move forward with measured accuracy.
View serviceWhether AI engines describe a platform selling to a global market correctly depends on its structured data and consistent content. GEO steps that could follow on from the SEO work at Tegoly are llms.txt, schema markup and a robots.txt policy.
View serviceWe carry B2B enquiries from LinkedIn Lead Gen Forms and Meta forms into the CRM without loss, and send the sales team's qualification decisions back to the ad platform. The automation layer runs on your server; the monthly report covers match quality and lead-to-sale conversion.
View serviceTegoly's platform runs on Azure; in a similar cloud environment we set up the CI/CD pipeline, environment and secret management and rollback steps, and hand them over in writing. The goal is to release without affecting live users.
View serviceTegoly is one of the cases on our CTO as a Service page: advisory work ran together with new screens, modules and performance work on the running product. For a company in Witten we likewise start with decision records, a technical debt inventory and a check of whose name the accounts are opened under.
View serviceWitten is a city in the Ruhr area of North Rhine-Westphalia, Germany. Our client Tegoly is based there; our team is in Istanbul.
The advantage of a city-level engagement is that the counterpart and the decision chain are clear. We work with one product, one team and an explicit priority list. Meetings are held in English and can be online or in person. Decisions and open questions stay written on the project board, so a topic raised in one meeting does not get lost by the next sprint.
Tegoly runs a digital signature and business process platform aimed at the global market. When we took it on, the system already worked; the need was to strengthen the user experience, close some integration gaps and become more visible in search engines. So the job was not to build a product from scratch but to grow a live product without breaking it.
New interfaces were designed around customer needs, and digital signature, document management and integration modules were developed. The front end runs on React and the server side on .NET Core, with data held in MSSQL and MongoDB.
The platform runs on Azure. Cache mechanisms and tuned server configurations improved page load times, and data protection was strengthened with the security layers of MSSQL and Azure.
Meta descriptions, content adjustments and technical SEO improvements increased the platform's visibility in search engines. For an international product, that means the right page can be found for the right search in more than one market.
Changing a system that users rely on every day, such as digital signatures, needs a more careful plan than building something new. On inherited projects like Tegoly we follow this order:
Istanbul is one hour ahead of Witten in summer and two hours ahead in winter. That gap is small enough for both teams to share most of the working day. On data protection, the GDPR framework applies to Tegoly's customers and users, and infrastructure and access decisions are made with it in mind. We cover the country-level details on our Germany page.
Development moves in two-week sprints. Priorities are set together at the start of each sprint, and a working demo is shown at the end. Work is visible on a Jira or Linear board, and a weekly status meeting and a sprint report keep both teams looking at the same picture. A direct channel stays open for urgent matters.
On a live product this rhythm has one more benefit: every change that goes out is recorded along with the sprint and the reason it was made. When the project ends or the team changes, those records and the technical documentation become a written handover package, so the product stays maintainable regardless of who built it.
The first meeting is free, and we reply within 24 hours. If you already have a product, the first step is to look at the codebase and the infrastructure together. After that we prepare a written proposal on either a fixed-price or a time and materials basis. On delivery, full ownership of the source code passes to you.
Wherever you are, the first meeting is free, online or in person.
