About
Hi, I'm Sam 👋
Cybersecurity researcher, software developer, and the writer behind this blog. I share developer insights, tutorials, and deep-dives on topics I'm passionate about.
Who am I?
I'm Shivam Kumar — a cybersecurity researcher and full-stack developer with over 5 years of experience in the tech industry. My journey started with Capture The Flag (CTF) competitions on platforms like TryHackMe (top 5 ranked) and HackTheBox, which gave me a deep foundation in offensive and defensive security.
Beyond security research, I build web applications and developer tools. I'm especially passionate about Astro.js, Linux, Neovim, and creating things that are fast, accessible, and well-crafted.
What I work with
- Languages: Python, TypeScript, JavaScript, C++
- Frontend: Astro, React, Tailwind CSS
- Security Tools: Burp Suite, Wireshark, Metasploit, Nmap
- Environments: Linux (Arch/Ubuntu), Neovim, Git
Why this blog?
I started this blog to share everything I've learned — from beginner-friendly tutorials to advanced security concepts. My goal is a space where developers and security enthusiasts can learn together, find practical answers fast, and stay current with modern tooling.
