Apps and web services
Mobile, desktop, websites, APIs, servers, and business platforms built as one reliable product.
Hi, I’m Alexander Diener — a senior software developer.
AI accelerates delivery. I stay responsible for architecture, testing, and quality.
Available for freelance projects
I am a multidisciplinary senior developer who turns ideas into reliable software—quickly, pragmatically, and with a clear focus on the result.
AI is a practical accelerator in my workflow. I use it for research, prototyping, implementation, tests, and documentation, while every result still passes through engineering review and verification. This combination lets me deliver substantially faster without trading away quality.
You bring the goal. I select the right technology and take the project from the first concept to a working release.
My experience spans web and desktop systems, Android apps, servers, ERP platforms, cloud integrations, simulations, machine vision, AI workflows, and robotics. I work comfortably across front end, back end, infrastructure, and physical systems.
That range means I can take on both a focused small assignment and a technically demanding product. The scope may change; the working principles do not: transparent communication, maintainable architecture, automated checks, and a solution that is ready for real users.
I am currently accepting freelance projects from any field—from a simple app or website to AI software and robotics. If the task is unusual, that usually makes it more interesting.

Process
We define the result, priorities, constraints, and the fastest sensible first version.
I build in visible increments, use AI to accelerate delivery, and keep the architecture under control.
Testing, fixes, documentation, deployment, and a clean handover for real-world use.
Have a project in mind?
From a focused MVP to a complex AI or robotics system.
