Message

At ATH Infosystems, I directed backend development for a telemedicine platform with real-time video, voice, and chat appointments, e-prescribing, insurance claims, and payment processing. The work contributed to a 270% increase in client revenue.

I also engineered a transport management system with real-time driver tracking and automated invoicing, and integrated Azure DevOps CI/CD pipelines that reduced release times by 60%.

Earlier, at The Merriman, I introduced a microservices strategy for a telehealth platform that achieved 99.99% uptime. I’ve also worked on healthcare coverage applications, HIPAA-compliant patient portals, financial systems, and cloud migrations across Azure and AWS.
