Hello! I'm Achmad Fawaz Ramadhani, an Information Technology student at Universitas Brawijaya in Malang, building web apps from database design to the interface people actually use. I work mainly with PHP, Laravel, JavaScript and Tailwind CSS, and I care about systems that stay easy to maintain after they ship.

My latest build is a point-of-sale system for a perfume refill store carrying more than 100 fragrance variants. I wrote the MVC architecture from scratch without a framework, added a recommendation engine using user-based collaborative filtering with cosine similarity, integrated dynamic QRIS payments under the EMVCo standard, and shipped role-based access control along with revenue and CRM dashboards. All 22 functional test scenarios passed.

Before that I spent six months at cmlabs as a QA engineer, writing test cases, documenting bugs, and retesting fixes with the developer team. I'm also certified in cybersecurity through BNSP and Cisco Networking Academy, comfortable with networking, hardware and IoT, and always open to new opportunities and collaborations.
