With a background in architecture, film design and project management at four Olympic Games, I started veering towards web development during the confined spring of 2020, while developing a new booking and management system for a small business I partially own. A project so enjoyable and gratifying that I felt driven to fully commit with digital product development, attending a few months later the Ironhack Full Stack Bootcamp in Madrid. Extremely passionate about assembling new ideas and tackling complex challenges, especially if it allows me to learn new technologies, put my research capabilities into practice and use my problem-solving faculties. As a calm and joyful teammate I'm always looking forward to soak up knowledge from talented colleagues or assist them wherever I can. Javascript (ES6), NodeJS, Express, React, NextJS, Webpack, MongoDB, REST API, HTML5, CSS3... Feel free to contact me at jaimeferncast@gmail.com
