About

Engineer with a product mindset and system-integration experience.

My work sits at the intersection of AI systems, application development, and business operations. I have hands-on experience building deep-learning features, integrating IoT diagnostic devices, designing cross-platform applications, and supporting production system rollouts.

I am especially interested in roles where I can connect AI capability with real business needs: improving workflow efficiency, turning data into usable products, and making complex systems easier for internal teams, partners, and users to adopt.
