I build things at the intersection of hardware and software.
Mostly whatever the project needs.
I'm an engineer based in Bangladesh. I work across electronics, embedded systems, fabrication, and full-stack software — usually all of them at once, because the projects I end up on tend to need it. Fab Academy graduate, founding engineer at Ghorar Dim, and on the lookout for interesting opportunities.
Technical engineer on a high-altitude balloon campaign that put a Bangladeshi flag at 32.45 km. Built the onboard electronics — Raspberry Pi, 433 MHz RTTY downlink, Ublox GPS, hacked GoPro — and the receiving Yagi out of copper rod and PVC sheet because nothing locally available would do. Recovered the box on the third attempt; the first two were defeated by batteries that didn't like the cold.
Drafted the proposal that won a USD 200,000 World Bank grant under HEQEP to set up a digital fabrication lab at Independent University Bangladesh. Speced and sourced the machines, prepared the space, and ran it up to the milestones the grant required. The lab has been operational ever since.
Community internet hotspots hosted at slum tea shops in Dhaka. Five-taka paper tokens for three hours of WiFi; OpenWRT on TP-Link MR3420 boxes, CoovaChilli captive portal, a Diameter AAA server, an SDN controller for fleet management. Three prototype generations, hand-painted enclosures, pilot deployment across multiple shops before I left for Fab Academy in 2019.
Nineteen weeks of digital fabrication at Fab Lab CEPT, Ahmedabad — laser, CNC, PCB design and fab, molding and casting, embedded, networking, machine design. Final project was PixelFace, a wearable pixel-display mask. Local instructor was Ohad Meyuhas (Stratasys); global was Francisco Sanchez (TECSUP).
Raspberry Pi HAT for vehicle CAN bus, designed at TeroLabs. Eagle CAD schematic and board, Fusion 360 enclosure, the OBD-II side protected against the kinds of electrical events cars actually produce. Became the sensor layer for a driver-behaviour analytics pipeline and a few other internal projects. Design files are public on GitHub.
CCSE, IUB
Fifteen years of saying yes to interesting problems. Robotics contests, a slum-internet startup, automotive telematics, kinetic animation devices, a fab lab grant, a praxinoscope or two, a weather balloon that came back from 32 kilometres up.
