Engineer focused on precision systems, CAD design, and hands-on problem solving.

Experience

Strong experience working on complex, high-reliability electro-mechanical systems in a safety-critical environment.

Technical Support Engineer
2023 - Present | Northampton General Hospital

  • Conducted preventative and corrective maintenance on complex radiotherapy systems involving mechanical, electrical, and vacuum subsystems.

  • Diagnosed faults across multi-system interactions, working methodically to identify root causes under clinical time pressure.

  • Performed calibration and safety checks on high-precision equipment where sub-millimetre accuracy is critical.

  • Worked within ISO 9001 and regulatory frameworks, maintaining accurate technical documentation and audit trails.

  • Developed practical solutions to improve reliability and efficiency, including automation of QA documentation processes.

  • Built internal tools to monitor system performance and identify early signs of failure, reducing downtime and improving response time.

Amazon Delivery Driver
2021 - 2023 | Amazon

  • Managed time-critical deliveries and route planning independently.

  • Maintained accuracy and accountability under pressure.

Customer Assistant
2017 - 2020 | Marks & Spencer

  • Worked in a fast-paced environment, developing organisation and prioritisation skills.

  • Delivered consistent customer service while managing stock and operations.

Engineering Lab

My Home Lab

Designed a custom 19” rack enclosure in Fusion 360, modelling real components and working around tight spatial constraints. Validated dimensions using a full-scale mock-up before build, identifying and correcting errors early. Refined layout based on real-world fit, access, 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

In my current role, I developed a custom application to sync real-time diagnostic data from clinical machinery to a centralized monitoring station. This had the following benefits:

  • Pre-Diagnosis: Enabled the identification of mechanical/software drifts before they resulted in system failure.

  • Data Integrity: Provided direct access to raw system logs, ensuring technical decisions were based on high-fidelity 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).

Technical Toolbox

Mechanical Design

  • CAD modelling (Fusion 360, AutoCAD)

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

  • Mechanical problem solving

Hardware

  • Systems maintenance: troubleshooting, fault-finding, preventative maintenance.

  • Electrical diagnostics: multimeters, oscilloscopes, signal generators.

Compliance

  • Regulations: ISO 9001, ISO 13485.

  • Documentation: report writing, equipment maintenance logs.

Software

  • Microsoft: Excel macros, PowerBi dashboards, PowerApps development.

  • Programming: microcontrollers, home automation, webpages.

Networking

  • Communication protocols: Matter, Zigbee, MQTT.

  • Infrastructure administration: IP addressing, subnetting.

  • Network security: VPNs, firewalls, segmentation.

Personal Profile

I am an engineer working in a high-reliability NHS environment, where precision and accountability are essential. My work involves maintaining complex systems where small deviations can have significant consequences.Alongside this, I develop practical engineering projects using CAD and 3D printing, focusing on designing components that work reliably in the real world.I am particularly interested in roles that combine design, build, and problem solving, and where I can contribute directly while continuing to develop my technical skills.I am looking to move into a hands-on engineering role within automation or manufacturing, where I can contribute to real systems and develop across design, build, and commissioning.
