Hi, I'm Restu 👋

Security-minded developer | Web security, incident response & automation — using AI to build faster, not to replace understanding.

What I'm About

I build real systems that solve real problems — attendance, payments, hardware interfaces — with security baked in from the start. When something goes wrong, I want to be the one who finds out why.

I use AI as a tool to accelerate development, not as a shortcut around fundamentals.

What I Explore	Tools I Use	Goal
Web Security	Burp Suite / Wireshark / Nmap	Find and fix vulnerabilities
Linux & Hardening	Kali Linux / Debian / Lynis	Build secure systems
Backend & Auth	Laravel / PHP / Python	Secure authentication flows
IoT & Hardware	ESP32 / NodeMCU / RFID	Harden hardware interfaces
Incident Response	Kaspersky KRD / Debian Live / Regipy	Endpoint triage & forensics

What I've Built

Project	What it does	Security aspect
restusec-rescue	Anti-malware rescue toolkit — endpoint triage, quarantine, offline forensics	Heuristic detection, dead-box triage, MITRE ATT&CK mapping
absensi-murid	Student attendance — QR scan, dashboard, auto-export	Session auth, rate limiting, input validation
absensi-guru	Teacher attendance — QR scan, dashboard, auto-export	Access control, secure QR generation
tu-yamasy	School payment system with QRIS verification	OTP, payment validation
absensi-rfid	RFID-based hardware attendance interface	Hardware auth, card mapping

Open Source Contributions

Learning by contributing to projects I actually use:

• statewave — AI memory runtime, added unit tests
• prd-maker — AI-assisted PRD tool, fixed linter bug
• okto-pulse — AI project management tool, fixed dev setup

Currently

• 🔐 Learning web security — PortSwigger Web Security Academy
• 🛡️ Building toward SOC Analyst path
• ⚙️ Automating incident response workflows
• 📡 Exploring network traffic analysis
• 🌱 Contributing to open source
