# About Me

### Hi, I’m Sachin 👋

I’m a **cybersecurity learner and CTF player** focused on **penetration testing and offensive security**.\
My learning approach is strongly **hands-on**, combining labs, structured learning paths, and continuous practice.

This GitBook is my **personal knowledge base**, where I document what I learn while developing real-world security skills.

***

### 🎯 Purpose

My goal is to grow into a **competent penetration tester** by:

* Understanding how systems and applications are attacked
* Learning the root causes of vulnerabilities
* Practicing ethical hacking in a legal and structured manner

> *Learn by doing. Document everything. Improve continuously.*

### 🎓 Education & Certifications

#### 🎓 Education

* **Bachelor of Computer Applications (BCA)**\
  *Specialization: Cloud Computing & Cyber Security*

#### 📜 Certifications

* **eJPT (eLearnSecurity Junior Penetration Tester)** – INE
* **ICCA (INE Certified Cloud Associate)** – INE

#### 🧭 Learning Paths Completed

* **CPTS (Certified Penetration Testing Specialist) Path**
