About Me
With over 10 years in the industry, I've grown from a full-stack developer into a Software Architect passionate about building robust and scalable solutions. While I have a strong history in demanding fields like the healthcare industry , my passion is applying architectural principles to any complex domain. Today, I'm channeling that passion into Artificial Intelligence, specializing in the design and development of innovative Agentic AI Applications .
