[See pricing](#preis) 175 € per hour, regular, net Concept first your approval before we start Human + AI including security review What for ## Custom things. Custom problems. When standard software, plugins and agency packages do not fit, this is the way. ### Custom websites & web apps Sites, portals and tools you cannot get off the shelf: booking, customer areas, configurators, dashboards. ### Interfaces & integrations Shop, CRM, payment provider or tracking not talking to each other? We connect them cleanly and traceably. ### Automation & AI workflows Automate recurring work in mail, data and processes, with clear rules and human approval where needed. ### Internal tools & data Reports, admin interfaces, import and export. The tool your team actually needs. ### Bugs, legacy & migrations Something is broken, slow or has to move to new tech? Analysis, repair, migration. ### Technical website & tracking problems Load time, technical SEO, measurement that is off: we find the cause and fix it. The team ## Three layers. One accountability. ### Specialised AI agents Built in-house, not public. Agents for analysis, code, tests and review work in parallel. That makes the build fast without paying for typing time. ### A human who is accountable A developer steers the agents, reads every change, makes the decisions and is your contact. AI proposes, the human approves. ### Security review A separate review round before handover: access rights, inputs, keys, dependencies, data protection basics. Findings are fixed and documented. The security review is a quality check, not a certified penetration test. Results depend on the task and environment.
