About Me

I am Dinesh Aswin S, a 20-year-old B.Tech CSE student at COER University, expected to graduate in 2026. I go by the username “esistdini”, where I share my learning journey, projects, and research in cybersecurity.

My primary focus is on penetration testing of web applications, backed by strong programming skills in Python, C++, Bash, JavaScript, and PowerShell. I have completed multiple penetration testing trainings with high scores and actively practice on platforms such as TryHackMe and VulnHub, participating in Capture the Flag (CTF) challenges to sharpen my offensive security skills.

Beyond penetration testing, I also explore malware analysis and gain hands-on blue team exposure through platforms like Let’s Defend, where I practice using tools such as Splunk to build SOC analysis skills. I am currently pursuing the eJPT certification, which I expect to complete by October 2025.

I am fluent in English and Tamil, with conversational knowledge of Hindi, Telugu, German, and Russian. My curiosity also extends into IoT security, where I experiment with devices like the ESP32 to better understand embedded systems and their vulnerabilities.

In addition to technical practice, I enjoy sharing knowledge by writing technical blogs on Medium and creating TryHackMe walkthroughs on YouTube.

I am an analytical thinker with strong problem-solving skills and a natural ability to adapt and collaborate. I’m also quite social, though if you’re a social engineer, I’d say give it a try (sarcastically, of course) 😉.

I am actively seeking internship opportunities to not only gain industry experience but also to learn, grow, and contribute meaningfully to an organization’s security efforts.
