About Me

I am a passionate programmer who has been making various software for almost a decade. I focus mainly on full stack, system design, and various low level aspects of computers. I’ve been discreetly working on FerricOxide OS and RigLang for the last couple of years. Although work is slow, things are slowly starting to take shape. Outside this, I’ve also recently resumed doing security research. To get my hands warmed up, I have been playing some CTFs as part of the team “Better_Call_SUST” — details available at https://ctftime.org/team/424264.

I’ve also been building a business (Axcerus) with my friends — you can DM me on LinkedIn for chats.

I sometimes write blogs here: https://mdgaziur001.me/blog

Works

SUST OJ

Online judge for SUST. Uses Svelte and Gin for backend and frontend. RabbitMQ is used as a message broker between the judge server and the backend server. The judge server is implemented using Rust. It utilizes ssandbox sandboxing library to execute untrusted code in a secure environment. Deployment strategy makes use of Docker, Kubernetes and Terraform.
