What I'm looking for

I am seeking opportunities that allow me to leverage my mobile development skills in a collaborative environment, focusing on innovative projects that challenge my abilities and foster professional growth.

I am a highly experienced .NET and Mobile Application Developer with a strong focus on Xamarin.Forms and .NET MAUI. My career has been marked by a proven track record of designing, developing, and optimizing robust mobile applications that enhance performance and user experience. I have successfully transitioned legacy systems to modern frameworks, delivering scalable, secure, and user-friendly solutions across various industries, including logistics, education, and finance.

Throughout my freelance projects, I have demonstrated my ability to migrate and optimize mobile applications effectively. For instance, I migrated a logistics mobile app from Xamarin.Forms to .NET MAUI, resulting in a 30-40% performance improvement and a significant reduction in crashes. My expertise in offline-first mobile applications has allowed me to design seamless synchronization solutions, ensuring data consistency even in low-network conditions. I am also a regular contributor to open-source projects, which reflects my commitment to continuous learning and community engagement.
