Engineering expertise

Web engineering

Next.js & React web application engineering

My web work covers public product websites and authenticated operational systems. I focus on workflows, information architecture, data loading, permissions, responsive UI, search visibility, and the backend contracts that make the interface reliable.

What this looks like in practice

  • Multi-department hospital workflows and facility operations in CliviQue HMIS.
  • Property-management lead intelligence and outbound operations in the RentPayor CRM.
  • Cargo, fleet, driver, finance, and staff administration in Macsim back-office tooling.
  • Public product websites with canonical metadata, structured data, sitemaps, robots controls, and intent-specific landing pages.
