• Designed and 3D printed the full enclosure system for a lithium-ion forklift battery — BMS housing, fire safety holder, power supply container, resistor case, and screen mount
• Built all models in SolidWorks from physical measurements; printed in-house in PLA and iterated on tolerances when parts failed
• Applied FDM anisotropy principles to fix structural column fractures — reoriented print axis and added fillets at stress concentration points, resolving the failure without adding material
• All five components shipped inside a battery delivered to a client

• Only mechanical designer on three concurrent wearable medical device housings: a smart headband measuring stress, temperature and blood pressure, an EMG muscle sensor, and a smart earbud
• One project arrived as a verbal description with no sketches or CAD reference — produced a complete 3D model, internal component layout, and photorealistic renders for stakeholder review
• Iterated on enclosure geometry to maintain sensor contact with skin while keeping parts compact and 3D-print-ready; coordinated dimensions with the electronics engineer on each device

Remote

• Product visualisation, modelling, texturing, and animation in Blender across seven years of client work
• Delivers complete renders from brief to final output — lighting, shading, Cycles rendering, and compositing in DaVinci Resolve and Photoshop

• Developing a low-cost ultrasonic pulse-echo device for non-destructive testing, using 1 MHz ultrasonic transducers in place of an expensive commercial NDT probe
• Phase 1 runs on an ESP32 with acrylic as the first test material; FPGA-based acquisition planned for Phase 2

• Designed the chassis in Blender, 3D printed it, wired the electronics by hand, and wrote the full firmware in Arduino C — the entire system built alone
• Implemented a cascaded PID architecture: an inner tilt-angle loop for balance and an outer velocity-feedback loop for controlled forward and backward movement
• Achieves stable balance within ±0.5° of setpoint using only an MPU6050 IMU and a complementary filter — no wheel encoders, no optical sensors
• Resolved I2C bus corruption from motor EMI through isolated power domains, twisted-pair wiring, and a firmware bus-reset timeout; all PID parameters tunable live over Bluetooth without reflashing
