    Hi, i am Malhadi Jr., an Ultra-Stack Developer, with 10 years experience in GNU/Linux system. I received an award in the field of web design when I was in high school. I have developed and manage a scraping tools using bash shell script to my 440+ user. And i also build the automatic deployment to DigitalOcean API. To secure my code, i create a service using ExpressJS to run the bash script in the server. Then use squid, privoxy, and TOR to secure the exit node network. Since 2020, i am focusing to learn Low-Level Programming (C/C++/x86 ASM) and write a thesis about Reverse-Engineering Lockbit Ransomware V2. Many new programmers didnt learn about OS internals. Involving how ELF Binary in Linux interact with kernel, how the network socket works, how the process in OS run dynamically, etc. I learn (Windows/Android) malware development too. So i have a skill which works both side. Attack & Defend. I mostly write & discuss about CyberCrime Underground in college. As for the Web Development stack, i use Python Flask + Gunicorn + NGINX Developed & Deployed in production using TMUX. I also maintain a private HomeLab (wireguard intranet) for development & tweaking purposes. I am very encouraged to learn new things that others think are impossible. And i love to give a mentoring & coaching for others ! Don't hesitate to discuss your problem with me. I am online everyday, from anywhere in the world. tags: #cprogramming #linux #elf #reverseengineering #malwareanalysis #wireguard #socketprogramming #networkprotocol #javascript #rust #bash #monero #tor #onionservices #python #flask #androidinternals
