Work Experience
Independent Contractor
Mercor
- Provided expertise in industrial design and mechanical engineering to improve models for a top AI lab.
- Managed team members, helping onboard those new to the project.
- Promoted to reviewer, overseeing other contributors' work.
Thermal Systems Architect and Advisor
Peec
- Developed the battery cooling architecture for a new EV platform designed for Dubai temperatures and UNECE Regulation 100 requirements.
- Turned an early thermal concept into a lightweight, manufacturable architecture covering pack layout, structural integration, sealing, and service access.
- Collaborated with suppliers to prepare the system for prototyping and regulatory testing.
Senior Mechanical Design Engineer
Advanced Innovative Engineering
- Developed the air-cooled 225CS SPARCS rotary engine concept to prototype stage.
- Delivered the foundation for an innovative air-cooled rotary engine program.
- Optimized thermal performance and packaging with respect to the customer's airframe, passing the PDR and CDR review stages.
Principal Thermal Systems Engineer
Charge Cars
- Turned prototype cooling and air-conditioning hardware into production-ready systems for a planned run of 499 vehicles, despite tight packaging and low-volume manufacturing constraints.
- Delivered thermal and AC systems using SolidWorks/NX and Ansys, cutting costs and ensuring compliance.
- Designed battery trays and bonding processes that passed safety testing.
- Delivered a production-ready system that scaled into low-volume manufacturing.
Chief Technology Officer
ActiveCell Technologies Limited
- Designed and commissioned a 22-machine 3D print farm with environmental control, remote monitoring, and automated production management.
- Spearheaded the development of a web quoting and job management system connecting customer orders to scheduling, material choice, and inspection.
- Scaled pandemic production to more than 15,000 face-shield frames in one month, then moved the product to injection molding.
- Developed an Innovate UK-funded custom-fit mask system using phone-based face scanning and on-demand manufacture. The PPE product achieved CE certification for medical use.
Senior Project Engineer
Arrival
- Helped deliver DevBot, an autonomous racing test vehicle, in four months by integrating batteries, drivetrain, high-voltage wiring, sensors, and computing hardware into a Ginetta LMP3 platform.
- Managed full-vehicle CAD integration across outsourced teams and resolved clashes, routing problems, and assembly risks.
- Built a SQL-based web PDM system for CAD approvals, version control, and BOM management across remote teams.
- Developed a rotary engine range-extender concept for Arrival.
Senior Project Engineer
O&H Vehicle Technology
- Secured £150,000 grant funding for the project to develop a lightweight ambulance.
- Directed the design and development of novel technologies, reducing vehicle weight and passing crash testing.
- Completed prototype trials, accelerating market entry.
