Senior iOS Engineer | Advancing in AI/ML



About

As a Senior iOS Engineer specialized in Swift and Objective-C, I’ve dedicated my career to crafting high-performance mobile applications with a focus on superior user experiences. I am now exploring the realms of Artificial Intelligence and Machine Learning (AI/ML) to enhance app intelligence and efficiency.

With a background in Electrical & Electronics Engineering, and strong skills in mathematics and programming, I am well-prepared to contribute to both iOS development and AI/ML projects. My passion for technology motivates me to continually learn and seek opportunities where I can apply my knowledge in iOS development to innovative AI/ML solutions.
