πŸ’« About Me

Enterprise Windows application developer with 2.25 years of experience building and maintaining a large-scale corporate email client. Specialized in Windows App SDK, UWP, MVVM architecture, and high-performance desktop systems.

πŸ”­ Currently Working On: Building and refining real-world software systems, with a focus on clean architecture, performance, and practical automation.

πŸ‘― Looking to Collaborate On: Projects that value solid fundamentals, system thinking, and long-term maintainability over quick demos and hype.

🌱 Currently Learning: Modern development workflows, automation, and agent-based approaches, while continuously strengthening core CS and engineering fundamentals.

πŸ’¬ Ask Me About: C#, .NET, Windows app development, software fundamentals, and how to learn new tech without getting lost in buzzwords.

⚑ Fun Fact: I enjoy breaking down complex ideas into simple mental models and questioning things that "everyone just accepts."
