Sobre mí
Greetings! I'm a hardware engineer leading battery, BMS, and motor-controller R&D at Bangladesh's first indigenous EV manufacturer.

I come from spacecraft power: a 222.8 W CubeSat solar array and PCDU built to NASA GSFC-STD-7000, and a full 1U CubeSat I built end to end. I design for the board that comes back from the fab, and I catch spec errors before they cost you a respin. Send your schematic or idea.... Lee más
