Custom software development in Cape Town
Xiaoyao Systems designs and builds software that fits the problem — web applications, backend systems and complete products for founders and businesses in Cape Town and across South Africa.
Who this is for
Founders and businesses who have a specific way of working, a product idea, or an operational problem that generic tools only half-solve. If the software has to match your domain — not the other way around — this is the work.
We work from Cape Town with teams anywhere in South Africa. The collaboration is direct: clear writing, careful engineering, and a shared picture of what should exist when the work is done.
Problems we take on
Custom software is useful when the process is yours, the users are real, and the cost of a clumsy workaround keeps growing. Typical starting points include a product that needs a proper first architecture, a web application that has to stay fast and understandable, or a backend that other tools and people will depend on.
- Web applications that people will use every day
- Backend systems, APIs and data models that can evolve
- Product software with a clear shape, not a pile of features
- Replacing spreadsheets, inboxes and disconnected tools with one system
How we work
We start by making the problem smaller. What has to be true for this software to be useful? Which parts are load-bearing, and which can wait? That conversation happens before a large build, so the first version has a reason to exist.
Then we design the system, implement it, and keep the surface area honest. We prefer small, thoughtful systems that work well over unnecessary complexity. Modern AI belongs in the product only where it genuinely improves the result.
- Shape the problem, users and constraints
- Propose an architecture and a first useful slice
- Build, review and refine the working software
- Leave you with a system you can understand and continue
What you receive
You receive working software, not a slide deck of possibilities. The exact deliverables depend on the engagement, but they are always concrete: a product or system you can use, with the engineering quality to keep using it.
- A working web application, backend, or product increment
- A clear model of how the system is put together
- Source code and the context needed to maintain it
- A practical next step if the product needs to grow
