Phuridis Koriparb
Hello, my name is Optra. I’m currently a senior majoring in Computer Science at Rangsit University. Beyond general front-end and back-end development, I’m particularly interested in the big picture of systems. I enjoy implementing Infrastructure-as-Code and setting up cloud environments—from designing cloud architecture with Terraform to managing system costs through FinOps using Infracost—ensuring that the systems I build are both stable and cost-effective.
Additionally, I had the opportunity to develop a production-level HR system (overtime management) for iRecruit. I was responsible for the entire process, from taking Figma designs and developing them further to providing feedback and refining workflows to better suit real users. This experience taught me how to handle changing requirements and system redesigns alongside senior team members, shaping me into a flexible developer who is well-prepared to tackle hands-on challenges.
Although I am an early-career developer, I am highly dedicated and eager to apply my skills in Cloud, FinOps, DevOps, and Full-Stack development to collaborate and grow alongside an experienced team.
