Production systems & architecture
Shipped engineering systems.
Seven verifiable production codebases solving real problems in Bangladesh — safety-critical RAG, multi-agent spatial routing, telehealth, and automation pipelines.
The Research-to-Production Loop
I operate under a simple engineering principle: research without deployed systems is speculative, and systems without empirical evaluation are fragile. Each codebase below is a complete, working software artifact with an accessible GitHub repository, containerized setup, and verifiable metrics.
Architectures derived from measured failure modes rather than generic templates.
Every project links to a public GitHub repository with clear setup instructions.
Built for Bangladesh challenges: flood triage, farmer advisory, e-GP tender monitoring.
