Joyboy__
I'm Abdul Hakim Shifat, known online as Joyboy__. I build security tools, solve CTF challenges, and explore Linux and low-level systems. My work blends software engineering, research, and open-source craftsmanship.
Pssst...
There's more.
About
I'm from Bangladesh, and I love turning difficult problems into working systems, open-source tools, and practical experiments. ᕙ(͡°‿ ͡°)ᕗ
I'm 24.000000000 years old and still learning something new every day.
Most days I split my time between CTF research, Linux tinkering, and documenting my work in blog posts.
I enjoy building tools, writing writeups, and sharing what I learn with the community.
My curiosity about computers led me into this field, where I get to merge systems thinking with security tooling and software craftsmanship.
- Linux
- Open Source
- System Architecture
- Cybersecurity / CTF
- Competitive Programming
- Dark Souls
I contribute to open-source tools, publish CTF writeups, and keep my GitHub active with security experiments, Linux utilities, and research notes.
The main technologies and frameworks I use to build scalable, user-centric applications:
IndieWeb
Simply put, IndieWeb is anything on the web that is hand-crafted, feels personal and gives a retro feel.
Cozy and nostalgic, like the early days of the internet. Since I became an adult, I felt this strong urge to recreate that feeling of wonder and excitement I had when I first explored the web as a kid.
Also, I had a lot of fun making my own 88x31 button, and you should make one too! :)
