PDF Crusher
A web tool that shrinks large PDFs so they pass website upload limits.
Some application portals reject files over 500 KB. This makes a scanned document fit without manual editing.

Abdulrahman Alnotefi
Computer engineer who builds practical tools and fixes technical problems, now studying cybersecurity.
I have worked in IT support and teaching, and I build small web applications and automation tools. I'm completing an MSc in Cybersecurity Engineering, with a particular interest in network security monitoring and digital forensics.
About me
I studied Computer Engineering at King Saud University and graduated in December 2024. Since then I've worked in two places where technology meets everyday people: a Ministry of Education IT support internship, and my current job teaching computer studies to children in Grades 1 to 5.
Outside work I build tools that solve a concrete annoyance: a PDF compressor for upload limits, and a Discord soundboard bot with a live dashboard. I enjoy debugging, and I'm using my master's degree to go deeper into how networks are defended and how incidents are investigated.
Projects
Two public projects, both built end to end. Open a card for a plain-English explanation and the technical detail.
Discord Soundbot and Web Dashboard
A Discord bot that plays sounds in voice channels, with a web page to watch and manage it.
The person running the bot can see who is in a channel and what is queued, without typing commands.
