Rezza Ramdhani Nashrullah

Fullstack Developer & Aspiring Database Administrator

The web is the surface, but databases are the soul.
In every beautiful web, there's a database working silently behind the scenes.

About

I hold a degree in Informatics Engineering and have over 2.5 years of experience as a Full Stack Developer at PT Atlantic Aksa Group, where I focused on web development, backend systems, and database management. My work involved building RESTful APIs, integrating digital payment systems, and maintaining technical documentation.

Over time, I developed a strong interest in Database Administration. I specialize in database schema design, query optimization, indexing, backup & recovery, and enforcing ACID principles to ensure data integrity. I’ve handled databases for transactional web apps involving mobile top-ups, bill payments, and payment gateways.

To support my transition, I’ve earned the Oracle Certified Foundations Associate (Database) and two CCNA certifications, and completed training programs such as Data Processing, Database Design & SQL Programming, and others via Digitalent and Dicoding. In my spare time, I enjoy reading books, watching movies, and occasionally watching programming problem-solving videos. I aspire to grow into a Database Administrator who ensures data systems are efficient, secure, and reliable.
