Is your Windows application giving you trouble, and the developer who built it is no longer available? Get in touch and let's see how to fix it — no need to rebuild everything from scratch. I develop and support Windows desktop applications in VB.NET and C#, connected to MS SQL Server or MySQL. I'm particularly interested in maintaining software that's already built, since it can often keep working well — it just needs some extra work to stay useful for its users. There's a lot of software out there with real potential that just needs some adjustments to reach it. For example: a small tech or services company that needs to maintain their VB.NET, C#, and SQL Server applications. In cases like this, I can help with: Error diagnosis and bug fixes New feature implementation (forms, reports, validations, exports and more) SQL Server / MySQL query fixes, stored procedures, and performance optimization Data grid and report adjustments I've successfully built software for a hospital and a bakery, designed for daily use. These experiences taught me to design with the mindset that the system can't fail, because people's work depends on it. I work with intellectual honesty and follow-through: if something's wrong, I'll tell you directly, and I stay accountable until it's actually fixed — not just until it looks fixed. I'm a Systems Analysis and Development Technologist (SENA Virtual), where I first learned VB.NET along with the fundamentals of building and maintaining software. If your system has bugs or needs new features, send me a message — I'll be happy to take a look before we agree on anything.
