Engineering Projects

Home Lab

Designed and built a custom engineering rack to improve equipment organisation, serviceability and thermal management, applying CAD, prototyping and iterative testing to optimise layout, accessibility and airflow.

This project required practical engineering decisions around mounting, alignment, and physical constraints, rather than purely digital design.

Specific tasks involved:

  • Architecture: Planning the project and selecting the devices.

  • Build: Designing the rack in Fusion 360, before assembling the enclosure, managing layout and wiring.

  • Cooling: Implementing adaptive speed fans for efficient thermal management and controlled airflow.

  • Automation: Multi-protocol (ZigBee, Z-Wave, Bluetooth, WiFi) integrated home automation system, with a variety of sensors and smart devices.

3D Printed Moulds

Designed and 3D printed silicone moulds for clinical use, focusing on repeatability, durability, and accurate volume control. Iterated designs based on physical testing to ensure consistent results and ease of use.

Quality Monitor

Problem: Engineers relied on manually reviewing diagnostic information from multiple clinical systems, making it more difficult to identify developing faults and monitor equipment performance over time.

Solution: Developed a custom engineering application to centralise and display diagnostic data from clinical systems, providing direct access to raw system information and enabling engineers to monitor equipment behaviour more effectively.

Outcome: Improved visibility of equipment performance, enabled earlier identification of mechanical and electrical degradation, and supported technical decision-making using high-fidelity diagnostic data rather than anecdotal reports.

Additional Practical Projects

  • Arduino-based motion system (multi-axis control).

  • Functional 3D printed components (enclosures, mounts).

  • Structural builds (e.g. chicken coop with monitoring and automation).

Technical Skills

Diagnostics

  • Structured fault diagnosis and electrical fault finding.

  • Test & measurement equipment: multimeters, oscilloscopes, and signal generators.

  • Systems maintenance, troubleshooting, and root-cause analysis.

Medical Engineering

  • Equipment lifecycle: preventative maintenance, calibration, and quality assurance.

  • Regulatory compliance: ISO 9001, IRR, IRMER, HASAWA.

  • Documentation: report writing and equipment maintenance logs.

Software

  • Programming & scripting: Python, microcontrollers, and webpages.

  • Microsoft Power Platform & Data: PowerApps development, Power BI dashboards, and Excel macros.

  • Process and systems automation (including home automation).

Connectivity

  • Communication protocols: MQTT, ZigBee, and Matter.

  • Network infrastructure: TCP/IP, IP addressing, and subnetting.

  • Security & remote access: VPNs, firewalls, and network segmentation.

Mechanical Design

  • CAD modelling (Fusion 360, AutoCAD).

  • 3D printing (tolerances, iteration, functional parts).

  • Mechanical problem solving.

Professional Profile

I enjoy diagnosing complex technical problems and restoring critical medical equipment to service within high-reliability clinical environments. Over the past three years, I have found the analytical aspects of engineering—structured fault finding, interpreting diagnostic data, and working collaboratively to resolve technical issues—to be the most rewarding. I am particularly interested in technical support roles where engineering expertise, customer communication, and remote diagnostics combine to maximise equipment availability and support healthcare professionals.
