Hire the Best Windows Forms Developers
in Romania

Hello friends, please call me Claud. I have been working as a Software Developer & Automation Engineer since November 2006, building up solid knowledge in both software and hardware topics. What I can help you with: ☑️ software solutions for complex and niche automation projects; ☑️ desktop, web, and cross-platform applications; ☑️ consulting, support, documentation, and suggestions. I am proficient with the use of the following technologies: ✔️ C# language and .NET Core(or .NET Framework); ✔️ Classic WinForms or WPF/XAML using MVVM pattern; ✔️ ASP .NET with Blazor and RazorPages; ✔️ Relational Database using Entity Framework; ✔️ TPL, multithreading, asynchronous I/O; ✔️ Custom controls, styles, and templates for UI/UX Design.

I’m a software developer mainly working with C# and .NET, focused on building practical desktop and mobile applications. Most of my experience comes from working on personal and long-term projects where I handled everything myself: data modeling, business logic, UI/UX, and overall structure of the application. I’ve worked mostly with WPF and MAUI, building data-heavy apps for things like inventory management, billing, reporting, and subscriptions. Besides .NET, I also build web applications and tools using PHP and JavaScript. I’ve developed and deployed my own web tools platform, which gave me hands-on experience with backend logic, frontend interaction, and real usage. I’m comfortable working independently, adapting to new problems or technologies, and navigating existing codebases, documentation, and third-party tools. I use Git/GitHub as part of my regular workflow. I have an Electrical Engineering degree and a Master’s degree in Computer-Aided Design. My master’s thesis was an OCR application for detecting and extracting text from images, which is also how I got deeper into document processing and structured data extraction. I also hold a system programming certification in JavaScript. Some of the projects I’ve worked on: - A veterinary clinic management system (desktop & mobile) covering patients, treatments, inventory, billing, reports, and subscriptions - A web directory platform where users can submit and list their websites, making it easier to discover and showcase online projects - Custom desktop applications with offline logic and custom UI systems What I can help with: - C# / .NET desktop and mobile applications (WPF, MAUI) - Application logic, data modeling, and persistence - PHP and JavaScript web applications or internal tools - OCR and document-processing related features - Improving, fixing, or extending existing codebases I prefer clear communication, realistic expectations, and writing code that’s easy to understand and maintain.
