About Me

Hello! I'm Jaber Ahmed — also known online as Jack Sargey — a passionate Full-Stack Web Developer, Ethical Hacker, and Tech Enthusiast driven by curiosity, innovation, and a commitment to empower others.

My technology journey began at the age of 13 when I was first introduced to computers. What started as curiosity has grown into a strong passion for web development, cybersecurity, OSINT, and creative digital work including photography and content creation.

Over the years, I've shaped this passion with purpose through volunteering, donating blood (O+), maintaining a healthy active lifestyle, and building a community on YouTube with 6.5k+ subscribers who share my enthusiasm for technology and learning.

What I Do
I specialize in developing modern, scalable, and user-focused applications using the MERN Stack, creating solutions that are both efficient and secure from the ground up.

My expertise includes:
Frontend: HTML5, CSS3, Tailwind CSS, Bootstrap, JavaScript (ES6), React.js, Firebase
Backend & Database: Node.js, Express.js, MongoDB, JWT Authentication, REST APIs
Tools & Workflow: Git & GitHub, Figma, Linux, Problem-Solving, UI/UX Awareness

Alongside development, I am deeply involved in ethical hacking and web security, with practical experience in identifying and mitigating vulnerabilities like SQL Injection, XSS, CSRF, and LFI. I regularly use security tools including Burp Suite, Nmap, FFUF, WPScan, and Nuclei to ensure code security and system integrity.

Supporting Students Beyond Tech
Beyond the tech world, I am committed to helping students achieve their dream of studying abroad. I provide comprehensive guidance on study visa processes, documentation, and post-arrival support. During the 2024–2025 season alone, I successfully assisted 150+ students begin their international education journey — particularly in Romania and other European destinations.

Values & Vision
I believe in continuous learning, knowledge sharing, and uplifting others through technology. I am adaptable, detail-oriented, and possess strong communication skills with a natural problem-solving mindset. My goal is to grow as a Full-Stack Developer and Security Researcher, developing deeper expertise in system architecture, networks, and cybersecurity to build robust, secure systems that make a positive impact.
