About Me

Building the future
of software

I'm a Full Stack Developer with over 20 years of hands-on experience building enterprise-grade applications across healthcare, cloud, and real estate domains.

My work spans HL7 & FHIR healthcare integrations, Laravel-powered SaaS platforms, Flutter mobile apps, and cloud-native architectures on AWS and Google Cloud. I turn complex requirements into elegant, maintainable solutions.

Beyond code, I invest in real estate — applying the same analytical rigour to property markets as I do to system architecture.
