03 — Selected Work

2026Founder & CTO

URO Bangladesh

Aerial robotics — custom UAV development

I founded URO Bangladesh and lead it as CTO, building the team and its engineering from the ground up. I direct the full stack of our aerial robotics, mechanical design, embedded systems and flight software and turn rough concepts into flying, field-tested hardware.

Founded the team and set its engineering direction.
Lead end-to-end UAV development across mechanical, embedded and software.
Designed and built AkashRokkhi, our custom in-house drone.

2025Software & Control Lead · ROV Captain

MATE ROV 2025

Team UIU Mariner · Marine Technology Society, USA

World Champion — Technical Documentation5th — Project Demonstration

I captained UIU Mariner and led the software and control system. I wrote the complete ROV control software that flies the vehicle, including the computer-vision tasks, and on the hardware side I designed and built the team's ROVs.

SoftwareBuilt the full ROV control software end to end, plus the computer-vision pipeline for the mission tasks.

MechanicalDesigned and manufactured all three ROVs: Octobot 1.0, Octobot 2.0 and Scorpion.
