Hi, I’m a software engineer with a strong focus on desktop and web applications, especially WPF and .NET technologies. I’ve rebuilt legacy systems, designed scalable components, and mentored teams to adopt new frameworks and best practices. I enjoy solving complex problems, collaborating with cross-functional teams across time zones, and delivering reliable software at scale. Outside of work, I’m passionate about teaching through my YouTube channel (WPF and programming topics) and exploring side projects like a RuneScape server emulator and network packet analyzer to deepen my understanding of system design and debugging.…Hi, I’m a software engineer with a strong focus on desktop and web applications, especially WPF and .NET technologies.
