This pivotal decision allowed me to transition into the world of web development and unleashed my creativity and problem-solving skills. My fascination with technology extends beyond coding. I possess hands-on experience in planning and building high-end desktop computers, showcasing my comprehensive understanding of both hardware and software aspects. This technical foundation has proved invaluable in my journey towards becoming a well-rounded full-stack developer. Throughout the bootcamp, I actively participated in the development of multiple web applications, collaborating within a team environment. Using Ruby on Rails, I engaged in every stage of the development process, from conceptualization to deployment. My proficiency spans both front-end and back-end development. On the front end, I enjoy crafting user-friendly web pages using HTML, CSS, Bootstrap, JavaScript, and Ajax. Meanwhile, on the back end, I use Ruby to implement CRUD operations and search functionality, ensuring seamless user experiences. I am eager to bring my skills and passion for development to a promising team, contributing to impactful projects and furthering my knowledge. Currently, I am expanding my skill set by delving into React.js, aiming to enhance my capabilities and stay at the forefront of web development trends. I am excited about the prospect of contributing to innovative projects and gaining valuable commercial experience with a forward-thinking team.
