Autonomous Navigation Rover on ROS 2
Repeatable localisation, planning and obstacle-aware navigation behaviour.
RoboticsSWL Pricing and Inventory Control
Operator-reviewed imports with change, exception, rollback and audit reports.
SoftwareThe engineer behind the systems.
Beyond project delivery, I play and help run my cricket club, mentor fellow students, and usually have a personal robotics or hardware build on the bench.
More about SajMultidisciplinary engineering.
My working pattern is consistent: understand the whole system, isolate faults and leave clear evidence for verification, commissioning and handover.

From the journal
Things I am learning, building and working through.
Inside the Gendio control board: power, protocols and radar positioning
A detailed design study of the ESP32-S3 controller, its power and protocol boundaries, and a radar-based positioning extension that preserves the existing PCB.
Designing a waterless solar-panel cleaning robot
CAD, traction and energy calculations, conservative coverage planning and an experimental roadmap for a modular dry-cleaning crawler.
