Fullstack Developer with DevOps Expertise. Skillset : Mobile : React Native Backend : Laravel Web Frontend : Vuejs /Reactjs Cloud : AWS, Digitalocean and Google Cloud My achievement : I was responsible for handling a B2C system that supports over 1 million users, focusing on its scalability, reliability, and seamless user experience. I played a pivotal role in designing a Financing System that handles millions of transactions, ensuring high availability, security, and scalability. The system was built with invoice financing as the base, and thanks to my future-proof database structure and backend design, it easily scales to support various types of financing. I successfully integrated multiple financial services, including RHB Financing and VISA Subsidiary, while ensuring the system met PCI-DSS compliance and passed critical security tests. As the main person in charge of security compliance, I ensured the system adhered to technical and policy security standards, making it robust and secure for handling critical financial data.
