I will create a high performance desktop application


About this gig
I build C++ desktop applications from the UI down to the database layer.
I've delivered a complete desktop app end to end: C++/Qt interface, C# backend, SQL Server database, Docker/Nginx deployment, and a CI/CD pipeline for zero-downtime updates. I don't just write code I handle the full stack of a desktop project so you don't need three different freelancers.
What I work with:
- C++ desktop applications (Qt, GTK, or other frameworks depending on your needs)
- Client-server architectures with relational databases
- CI/CD pipelines and automated deployment
- Low-level systems programming in C/C++
- Modernizing or refactoring existing applications
I currently work in R&D at a connected systems company, writing C/C++ daily in a technical, production environment.
I care about code that's still maintainable in ten years, not just working today. minimal dependencies, clear architecture, no unnecessary complexity.
Message me before ordering if your project doesn't fit the packages below I can scope it properly first.

FAQ
Do I get the full source code?
Yes, you receive complete, commented source code with every order. No locked-in dependency on me to maintain it afterward.
I'm not sure which package fits my project. What should I do?
Message me with a short description of what you need before ordering. I'll tell you honestly which package fits, or if your project needs a custom quote.
Can you work with an existing codebase instead of starting from scratch?
Yes. modernizing or refactoring existing C and C++ applications is something I regularly do. Share the codebase (or a description of it) in a message first so I can scope the work accurately.
What if I need changes after delivery?
Each package includes a set number of revisions (see package details). Additional changes outside that scope can be arranged separately.
