Engineering
Research-driven software systems.
A selection of research-linked software and engineering projects, from Bengali agricultural advisory and offline education to disaster-response prototypes. Source and demo links are listed where available.
From findings to working systems
Each project below started as a research question or a measured failure mode and became working software with public source code. Benchmarks without systems are incomplete; systems without measurement are fragile.
Architectures derived from measured failure modes rather than generic templates.
Every project links to a public GitHub repository with setup instructions.
Built around Bangladesh challenges: farmer advisory, flood triage, tender monitoring.
