Solve problems. I help agencies and in-house teams investigate technical problems, review security and infrastructure, and finish work that has stalled. I work directly with code, configuration and servers, either alongside your team or as white-label support for a client project.

Visible problem **“The AI-built prototype works locally, but not in production.”** 2. Actual cause **Error handling, configuration and deployment are incomplete.** 3. Right assignment **Review the existing code, close the gaps and put the application into reliable operation.** Services ## Where I can step in. ### Agency and white-label technical support I can take on a defined part of a client project, work through an existing codebase or help your team with integrations and internal tools. I can collaborate directly with the agency or work behind the scenes within your client relationship. ### Security review and troubleshooting I investigate faults, review code and configuration, assess security issues and implement the agreed fixes. The result may be a corrected application, a safer setup or a clear technical finding your team can act on. ### Infrastructure and ongoing support I configure Linux servers and services, troubleshoot hosting, and improve deployments, backups and monitoring. This can be a defined infrastructure task or recurring support for agreed systems. ### AI project repair and completion I review existing code, fix faults, complete functions and integrations, then improve deployment, security and maintainability where needed. What can be reused depends on the existing code and the project requirements. [Discuss your AI-built website or application →](https://contegus.com/en/#contact) [Repair and completion details in German →](https://contegus.com/leistungen/ki-projekte-fertigstellen/) For agency work, I can handle one defined task, support delivery behind the scenes or stay available for recurring technical work on agreed systems.

A completed Shopware store had never launched because a consumer checkout did not match the sales process. I built a separate catalog where customers can search, filter and collect products for one inquiry.

My background in security research shapes how I approach them: I check what is happening, explain what matters and implement the work we agree on. I read every inquiry myself, do the technical work and stay your direct contact throughout the project. How I approach the work 1. **Investigate**Assess code, configuration, logs and dependencies. 2. **Implement**Fix faults, secure systems or complete missing functionality. 3. **Verify**Test the change, document the result and hand it over cleanly. You work directly with me throughout the project. Contact ## What do you need help with? Email me about the application, infrastructure or client project involved and what needs to be fixed or finished. If this is agency work, tell me whether you need direct collaboration or white-label support. For an existing problem, include what has already been tried. A few sentences are enough. I will reply personally and tell you whether I can help. [Email kontakt@contegus.com](mailto:kontakt@contegus.com)
