Summary About Me.Hello! I’m Ahmad Alif Sofian, a Software Developer with hands-on experience in building and maintaining web API middleware services, primarily using Node.js and Express.js. Currently, I work at PT Phincon, where I develop and maintain middleware APIs for the MyTelkomsel App. My responsibilities include implementing request validation, consistent response formatting, error handling, writing unit tests with Jest, and supporting SIT/UAT configurations. Previously, I participated in an intensive Fullstack Developer Trainee Program at PT Phincon, covering technologies like ReactJS, React Redux, Redux Saga, Express.js, Redis, and MySQL. During this program, I completed a final project — EasyWash, a local laundry management web app featuring OpenStreetMap integration and real-time chat with Stream.io. I also gained early experience as a Software Developer Intern at PT Javan Cipta Solusi, contributing to a Laravel and VueJS-based web project.
