About this gig

Need custom software built for Windows, not something patched together from a template?

I build desktop applications in C# clean, functional, and built around exactly what your workflow needs.

Whether it's a small utility to automate a repetitive task, a business tool to manage your data, or something more complex with a full UI and database, I write maintainable code that actually works the way you expect it to.


What you get:

  • Custom-built C# (.NET) desktop application
  • Clean, functional UI (WinForms or WPF depending on project)
  • Local data storage or database integration where needed
  • Installer/setup file for easy deployment
  • Source code included


How it works:

  1. Message me with what you need the software to do
  2. I'll confirm scope and the package that fits
  3. I build, sharing progress at key milestones
  4. You test and give feedback, I revise
  5. Final delivery with source code and a walkthrough of how it works


I take the time to understand exactly what you need before writing a single line message me first so I can scope your project accurately.

I'm a full stack developer based in Lagos, Nigeria, building fast, production ready websites, web apps, and backend systems. Since 2024 I've shipped real platforms, university admissions and payment processing, AI powered content pipelines, secure REST APIs with authentication, and e-commerce systems with live payments. I work with React, Next.js, Node.js, and FastAPI, and I build things that hold up under real users, not just demos. I'm new to Fiverr, not new to building things. My work is already live and running. Let's talk about what you're building. WAT (UTC+1) timezone.
