What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for growth in AI and machine learning.

I am a dedicated AI Software Engineer with over a decade of experience in delivering high-performance solutions in deep learning, computer vision, and cloud platforms. My journey in technology has been marked by a commitment to excellence, achieving over 94% detection accuracy in AI-driven systems and reducing failure rates by 15% in complex applications. I excel at translating data into actionable insights, utilizing tools like TensorFlow, PyTorch, and OpenCV to drive innovation.

In my current role as a Senior AI Software Engineer at Artera, I engineered a heart condition detection system that significantly improved diagnostic accuracy. My work has consistently focused on enhancing model performance and user outcomes, demonstrated by my successful implementation of deep neural networks and advanced data cleaning techniques. Previously, at Prosodica, I developed a multi-object tracking system with remarkable accuracy, showcasing my ability to tackle complex challenges and deliver robust solutions.
