I’m a mechanical design engineer focused on design-for-manufacturing and parametric CAD, turning concept models into production-ready assemblies with robust part documentation and traceability. I’ve led mechanical system design across welded aluminum structures, laser-cut sheet metal, CNC machining, injection-moulded plastics, and production-grade 3D printed components—then validated releases through FEA, multibody dynamics, and CFD workflows before they reach the shop floor. In my current work, I design and own the full mechanical build of a differential-drive robot platform for a 200-unit production run, including chassis structure, suspension modules, enclosures, BOMs, and part numbering with material and weld traceability built in. Earlier, I’ve supported automation and robotics deployments in industrial and port environments, built digital-twin style validation pipelines, and improved real-world performance through field feedback—so the designs are not only CAD-accurate, but manufacturing- and operations-ready.…I’m a mechanical design engineer focused on design-for-manufacturing and parametric CAD, turning concept models into production-ready assemblies with robust part documentation and traceability.

Work Experience

Robotics Design Engineer at Sand Dynamics Ltd.

April 1, 2025 - Present

Owned mechanical design for a differential-drive AMR gearing into a 200-unit production run: aluminum T-slot chassis, laser-cut welded suspension modules, electronics enclosure and outer shell. Sized a drive-wheel suspension module using first principles spring sizing (including travel and preload/bottom-out checks) and validated motion behavior with SolidWorks Motion. Defined DFM strategy for welded aluminum frames (material selection for weld fatigue, bolted fatigue-critical joints, weld routing through high-stress zones with start/stop crater placement in low-stress areas, and jig-free fit-up features). Authored part-numbering and production BOM conventions to keep design changes from forcing re-numbering, and built per-unit material/weld traceability columns (alloy heat, laser cut lot, weld lot, and WPS). Designed thermal management for an ~70 W internal electronics load in hot ambient conditions using airflow/vent sizing and ducting, validating via Flow Simulation against inlet-ai

Robotics Lead at CARE-YU Automation

September 1, 2024 - March 31, 2025

Led design for an automated in-line safe-food processing and packaging line with delta-robot pick-and-place cells, end-effectors, and tooling for delicate non-rigid product handling guided by machine vision. Reduced prototyping cycle times by 40% through design iteration. Built a digital twin in NVIDIA Omniverse to enable virtual validation of workcell layout, reach envelopes, and clearances prior to commissioning. Delivered a pick-to-light system for a major automobile manufacturer.

Design & Robotics Engineer at Doozy Robotics

February 1, 2024 - August 31, 2024

Integrated sensing and compute hardware into a 2-ton tugging AMR for an automotive manufacturer, covering mounting/bracket design, sensor placement, and cable routing, alongside autonomous docking and navigation software using C++ and ROS1/ROS2. Developed machine-vision algorithms and a vision-based transform system on Intel NUC and Arduino hardware.

Automation & Production Engineer at AI Drivers Ltd (UK)

July 1, 2022 - December 31, 2023

Commissioned and integrated a full autonomous sensor suit (LiDAR, vision, GNSS, radar, and safety PLCs) on 20-ton driverless port trucks (Y T223/Y T233) operating in live container terminal environments in PSA Singapore, PTP Malaysia, and DP World Jebel Ali. Managed mounting alignment and calibration under outdoor marine service conditions. Performed field failure analysis feeding back into hardware revisions and provided remote support for multi-site production debugging. Executed digital map mapping and data collection campaigns at DP World Dubai and supported V2X device deployment for port automation.
