Web Developer

Dec 2022 – May 2023 · 5 mos · Bengaluru, Karnataka, India · On-site

During my tenure at Openturf Technology , I immersed myself in a diverse range of front-end technologies, mastering HTML for structuring content, CSS for styling, JavaScript for interactivity, React for building dynamic user interfaces and Bootstrap for responsive design. Additionally, I utilized VS Code as my primary code editor and leveraged npm for package management.
As a key contributor to a real-time Full Stack Web Application centered on Electric Vehicles Slot Booking, I applied my expertise in HTML, CSS, JavaScript, React, and PostgreSQL. This hands-on experience allowed me to actively participate in creating a user-friendly interface that enabled seamless interaction with features like station search, slot booking, history tracking, and payment gateways.
Throughout the internship, I honed my skills in Re dux for state management, employed Jest for testing, and explored UI component libraries like Material-UI and Ant Design. This practical exposure significantly enriched my understanding of front-end development, empowering me to create both aesthetically pleasing and functionally robust web applications.
