Engineering clarity into critical systems

I'm a Senior Software Developer based in Abu Dhabi, UAE, building mission-critical, secure software — including prehospital emergency medical systems used in the field. My work focuses on air-gapped applications where reliability and 24/7 availability are non-negotiable.

I bridge robust .NET back ends with polished Angular and Blazor front ends, ship cross-platform mobile apps with Ionic, integrate AI safely into isolated networks, and maintain the open-source sensei-uaepass library for UAE Pass authentication.

01

Secure by design

Air-gapped, government-grade apps with hardened architectures and patient-data protection.

02

Prehospital focus

Field-first emergency response tooling for paramedics and command teams.

// focus area

Prehospital & emergency medical systems

Software that has to work the moment it matters most — in ambulances, at incident scenes, and on isolated government networks.

Digital field records

Structured digital documentation for ambulance crews — fast to complete under pressure and safe to store.

Offline-first field reliability

Apps that keep working with no connectivity and sync automatically when the network returns — built for real field conditions.

Incident & response workflows

Tooling that supports dispatch-adjacent and incident workflows, connecting field teams with command and operations.

Secure health data handling

Patient health information handled on air-gapped, isolated networks with strict access controls and auditability.

Health authority integration

Integrations with hospitals and health systems (Shafafiya), plus identity via UAE Pass and ICA.

Always-on availability

Architected for 24/7 operation where downtime is not an option — resilient services and CI/CD tuned for isolated networks.
