# Custom Desktop Software Development (C# / .NET)

> I have been building desktop software since my first corporate C# project, written on request before I started university. Highlights include an award-winning UAV ground control station, a software-distribution platform for Otoeko that automates licensing and installation, a sales and stock-tracking program that runs without any database engine, and an event-management app for Bursa Technical University’s SKS unit.

## Problems it solves

- Stock, sales, customer or event tracking still lives in spreadsheets or on paper.
- You need software that talks to a device, a sensor or a flight controller (serial, TCP/UDP, MAVLink).
- The program must run fast and reliably on a local PC, without an internet connection.
- You want to license your software to customers and ship it with a one-click installer.
- An old program has become hard to maintain and needs restructuring.

## What you get

- A Windows desktop application (C#, .NET, WinForms) with a modern UI
- Layered, SOLID architecture, with multi-threading where needed
- Database or file-based storage, reports and charts
- Device / hardware communication (serial, TCP/UDP, MAVLink)
- Installer, licence management, source code and documentation

## How we work

1. **Free discovery call:** I listen to your need, your current system and your goals, and we talk openly about what is technically feasible.
2. **Scope and quote:** A written scope, milestones, an exact price and a timeline. No surprise costs — what is included is clear from the start.
3. **Build and regular demos:** We agree on the screens and flows first; at every milestone I share a build you can install and try.
4. **Test and handover:** Testing with your real data, then handover with an installer package and user documentation.

## Tech stack

C#, .NET, WinForms, Multi-threading, SQL Server, MS Access (OleDb), MaterialSkin, Serial / TCP / UDP

## FAQ

### How much does custom desktop software cost?

The price depends on the scope; there is no fixed price list. The easiest way to start is Discovery & Feasibility: requirements analysis, technical roadmap, rough plan and proposal document. Discovery and feasibility are free. The price and timeline of the project itself depend on its scope and come as a firm quote at the end of that work.

### Should I build a desktop app or a web app?

Desktop fits when you need offline use, local hardware communication or high performance; web fits when people need access from different places and devices. Hybrids are possible too.

### Can the program work without the internet?

Yes. For example, the Hızlı Satış (Quick Sale) program runs fully locally and file-based, with no database engine at all.

### Do you build software that talks to devices or hardware?

Yes. The ground control station talks to flight controllers over MAVLink, and the C# interface of the GPS object-tracking system processes data arriving over XBee. Serial, TCP/UDP and HTTP communication are routine work for me.

### Is it Windows only?

My desktop projects are mainly on Windows and .NET. If you need Linux support, we evaluate cross-platform options with .NET Core in the discovery call.

### Do you work remotely, and in which languages?

Yes. I am based in Türkiye (GMT+3) and work remotely with clients worldwide; meetings are held in Turkish or English and scheduled around your time zone.
