Hi, there!

I'm Arbaz Hussain, located in INDIA 🇮🇳. I am currently employed as a Smart contract security triager at Immunefi, with a strong inclination towards Blockchain & Web security research.

My professional interests revolve around blockchain and web technologies, with a strong desire to conduct significant security research in these areas.

When I'm not working, I enjoy immersing myself in diverse cultures and embarking on new travel adventures. I'm also a passionate learner of human behaviors, self-awareness and religious philosophies, which allows me to broaden my perspective and understanding of the world.

Personal Projects


The Cimex project is designed to provide automated security monitoring solutions and reconnaissance processes. To this end, I developed a framework that streamlines bug bounty manual work and employs scalable technologies such as AWS Lambda, Celery tasks, Redis queue, and the Django framework. As part of the documentation process, I have also created a brief video that provides an overview of the framework's key features and functionality.
