Hi, my name is
Razan Dradjat
Informatics student at Telkom University. I break systems to understand them, then help make them safer. Focused on penetration testing and network & IoT security.
01 / about
About
I'm a Bachelor's student in Informatics at Telkom University (GPA 3.56), specializing in cybersecurity. My work spans web application penetration testing, Software-Defined Networking security research, and IoT exploitation. I'm a certified ISO/IEC 27001:2022 Lead Auditor. I also teach. As a practicum assistant, I help students understand programming, networking, and databases.
I enjoy the whole loop: finding a weakness, understanding why it exists, and writing the fix and the report that keep it from coming back.

Experience
Penetration Tester Intern
Jul 2026 – PresentConfidential Client (NDA)
- Performed web application penetration testing on client-assigned targets, uncovering vulnerabilities across authentication, input validation, and session management.
- Documented findings and delivered actionable remediation recommendations to strengthen the client's security posture.
Practicum Assistant
Sep 2025 – PresentInformatics Lab, Telkom University
- Guided students through practical sessions on Programming Algorithms, Computer Networks, and Databases.
- Evaluated assignments and gave one-on-one mentoring to help students complete their final projects.
IoT Security Research Group
Nov 2025 – PresentIoT Studio Laboratory, Telkom University
- Researched IoT security vulnerabilities with a focus on network-layer threats and device-level exploits.
Cybersecurity Intern
Aug 2025 – Oct 2025MBC Laboratory, Telkom University
- Compared two automated threat-mitigation methods in Software-Defined Networking (SDN) for response speed vs. network stability.
- Built a Python framework to benchmark latency, throughput, and overhead for Direct-Blocking and Meter-Based mitigation.
- Authored a scientific paper on adaptive intrusion prevention and a proposed enhanced security model.
Member
Oct 2024 – PresentAI Lab, Telkom University
- Collaborated on AI/ML challenges within the AI Lab study group.
- Developed a computer-vision bird-detection model using YOLOv5.

SLICE — Log Compression Engine
A self-hosted preprocessor that compresses SIEM logs before they reach an LLM. On an 86,839-line SSH auth log it cut tokens from 2.33M to 504 (−99.9%), and the model still flagged the brute-force attack correctly. Raw logs stay on your machine.
