Years of experience

I build web and mobile applications end to end — from database schema and API design to the pixel on screen. My work spans e-learning platforms, compliance systems, healthcare staffing tools, and developer utilities.

I care about systems that are simple to operate, honest about their trade-offs, and documented well enough that the next developer (or the next Claude Code session) can pick them up cold.

  • Full-stack development across desktop, web, and mobile
  • Spearheaded and built systems for inventory, ERP, hospital information, staffing, property management, and employee management
  • Migrated a legacy desktop hospital management system to a full web app
  • Led and coordinated developers, including DevOps and deployment
  • Hands-on networking — setup, configuration, and troubleshooting
