Chi sono
Greetings!
I'm a hardware engineer leading battery, BMS, and motor-controller R&D at Bangladesh's first indigenous EV manufacturer.
Signature work: a 300 W MPPT charge controller, a 150 A drone power module, an STM32G473 flight controller, and a 2.4 GHz Zigbee node at 0.8 µA sleep.
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.
