• Ability to design and implement systems that are effective, intuitive, and maintainable, with attention to code clarity and operational simplicity.
• Solid understanding of complex data structures, object-oriented principles, exception handling, and memory management techniques in C.
• Adaptability and eagerness to learn new technologies, with comfort working in evolving technical environments and embracing feedback.
