About

I am Rizal Ihwan Sulaiman, a Back-end Developer and DevOps Engineer focused on building reliable, scalable, and efficient applications. I specialize in the Laravel ecosystem and have solid experience in database management, system deployment, infrastructure operations, and software architecture.

I am passionate about solving technical challenges, improving system performance, and delivering high-quality solutions based on business and client requirements.

In addition to back-end development, I also have experience with modern front-end technologies such as Bootstrap, Tailwind CSS, and Next.js.
