Convergence Medical · Brisbane

• Design, integrate and maintain C++17 control software for a networked surgical robotic system on Linux, spanning multithreaded processing, kinematics, device command and observation over CAN and UDP.
• Translate actuator-vendor protocol constraints and bench findings into testable startup, shutdown, joint-limit, fault-recovery and operator-diagnostic behaviour.
• Investigate the complete hardware path with packet captures, repeatable test runs and p50/p95/p99 timing comparisons to isolate communication bottlenecks.
• Built a physics-backed digital twin for hardware-free integration and regression testing; strengthened CI with unit and integration suites, coverage and MC/DC gates, static analysis and sanitizers.
• Also delivered a React Native and TypeScript healthcare application with AWS-backed authentication and offline workflows.

• Developed security frameworks for dependable multi-robot systems, focusing on attack detection and defence.
• Modelled transport-layer denial-of-service scenarios in Python with Kalman-filter methods, then validated and visualised the results on Robotarium.

• Documents requirements interpretation, device integration, safe shutdown behaviour, timing evidence, simulation and the limits of transferable experience without exposing proprietary source.

• Independent C#/.NET 10 project using RabbitMQ over AMQP and SQLite to exercise publisher confirms, manual acknowledgement after commit, duplicate identity, delayed and reordered delivery.
• Includes xUnit decision tests, a real broker integration test, Docker Compose, GitHub Actions and PowerShell entry points.

Independent learning project; not train-control, SCADA or rail-domain experience.

• Browser-native URDF parser and forward-kinematics viewer using JavaScript and three.js, with constrained joints, live tool-centre coordinates and optimised meshes.
