Working as a software engineer right after graduation and with over 7 years of diverse experience in the tech industry, I have had the opportunity to work with various technologies including backend, frontend (app and website), and virtual reality (AR/VR) and across domains like entertainment, fintech, and health. During this period, I advanced into architecture and database design, managing the end-to-end development cycle of various projects.
