I design dependable electrical systems, build clear engineering documentation, and create software that turns complex technical work into useful tools.
I'm Nandakumar M, an Electrical Design & Development Engineer at Johnson Lifts & Escalators in Kerala, India.
My professional work is centred on escalator electrical systems, control circuits, schematics, wiring diagrams, BOMs, engineering revisions, testing, troubleshooting, and production support. Beyond core engineering, I build desktop tools, web applications, learning platforms, and automation workflows for real-world problems.

Diploma in Electronics Engineering — Government Polytechnic College, Perinthalmanna
My earlier work across automotive quality and assembly, CNC operation, dimensional inspection, and video editing shaped the way I approach engineering today: with precision, process discipline, practical problem-solving, and clear visual communication.
