About

My name is Ahmad Jundullah Justan, I have been working as a Fullstack Developer for over 7 years. In my last company at BPJS Ketenagakerjaan, I built a Correspondence And Digital Archive System using ExpressJS, NuxtJS, MariaDB, and Redis. During my time there, I have fixed several bugs and security vulnerabilities and significantly enhanced application performance such as decreased time in batch download pdf and optimizing SQL query. I have a strong background in PHP and NodeJS frameworks including Laravel, Codeigniter, ExpressJS, and VueJS. Additionally, I have experience with MariaDB as a database solution and Redis as a caching system. With this expertise, I am well-equipped to contribute effectively to your team. Using Fedora Linux as my daily driver has strengthened my technical skills and ability to navigate and troubleshoot in a Linux environment, which is crucial for any development role. Furthermore, I am also familiar with CI/CD and cloud computing tools, including ArgoCD, Openshift, Docker, Jenkins, and GitLab. This expertise has allowed me to effectively automate workflows, improve deployment efficiency, and enhance collaboration within development teams, ultimately driving faster delivery of high-quality software solutions. Thank you for considering my application. I look forward to the opportunity to discuss how my skills and experiences align with the needs of your team. Sincerely, Ahmad Jundullah Justan
