Backend engineer building reliable, high-criticality distributed systems for real-time infrastructure.
What I'm looking for
I’m a Backend Engineer focused on building and maintaining high-criticality systems in real-time infrastructure environments. At Indra, I maintain CNS/ATM backend services powering surveillance infrastructure across 15+ countries—systems where a production incident directly impacts air navigation services.
I care deeply about reliability and clean architecture, especially when downtime is costly. I diagnose and resolve production incidents in distributed systems, and I contribute to RMMS platform improvements that cut on-site technical interventions from 5+ hours of travel and manual work to ~5-minute remote operations—delivering a 98% reduction in intervention time per radar installation.
Before Indra, I modernized mission-critical software at SICE and Babel. At SICE, I developed the fire safety module for the North East Link tunnel project in Melbourne (AUD 15B+), integrating PLCs, sensor networks (smoke, ventilation, sprinklers), and control interfaces into a unified real-time system.
At Babel, I led a full migration of a legacy control application from WPF/.NET to WinUI 3 (Visual Basic → C#/.NET), improving responsiveness and thread-safety for an operator-facing control UI. I apply MVVM to decouple UI from business logic, and I refactor legacy components to align with modern .NET standards and separation of concerns.
