Ahlyab is an independent developer whose compact GitHub portfolio focuses on everyday utility tools that solve two common user headaches: password security and online-course affordability. Password Checker is a lightweight desktop client that quietly hashes any password you type, then compares the hash against public breach databases such as Have I Been Pwned; within seconds it reports whether the credential has ever appeared in known leaks, letting users retire compromised phrases before they can be exploited. Udemy Coupon Fetcher takes a different angle on value, scraping and aggregating limited-time 100%-off coupon codes from community forums and instructor promotions; the program presents the vouchers in a searchable list so learners can enroll in paid courses at no cost while the offers remain valid. Both utilities are portable, open-source, and designed to run on any recent Windows machine without extra dependencies, making them convenient additions to a thumb-drive toolkit or a fresh OS setup. Ahlyab’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always installing the latest upstream builds and supporting batch installation of multiple applications.
