About me.

Born and raised in Curitiba, Brazil, I started to write HTML with 15 years old, and never stopped since then. Always working as a front-end developer, I’m also on to mobile development, ux/ui designing, IoT and gadgets.

  • Livetouch


    Intern / Web Developer | 09/2015 - 12/2017

    My first job experience, I started at Livetouch as a front-end intern. There I've worked on several projects - from websites, dashboards and digital products - and also helped the team interviewing new interns. After 10 months, and most part of this time as the only front-end developer in the house, I was promoted to a JR front-end developer position.

    In almost 2,5 years at Livetouch, I worked with jQuery, Angular, React, Vue, Ionic and also learned a little about Android development.



    Front-end Developer | 01/2018 - 07/2019

    During my time at EBANX I was the front-end developer inside marketing area. There I helped to develop a new version of the company's business website - as part of Performance team - and also could help a lot of other teams - like Culture, The Shoppers (which has a blog), and the Content team.

    Besides having to learn how to deal with HubSpot, which required me to use a lot of vanilla JS, there I used Vue to create new hotsites - like the careers page - and WordPress for blogs.

  • Bcredi


    Front-end Developer | 07/2019 - 03/2020

    I've joined Bcredi to help them grow their products. After a while working with the product team, I moved to work with Growth team to help solve some technology issues within the marketing.

    There I helped to develop a new version of the company's design system - using PostCSS and vanilla JS - and developed a lot of new components for the React version; also helped the front-end chapter to standartize some patterns and tools for development.

    As part of the marketing team, I helped to develop a new interest calculator and rewrote the institutional site, from Gatsby to HubSpot with vanilla JS.

    My current full-time job, Paraná Banco is a brazilian private bank focused on payroll loans for retirees, state pensioners, civil servants and the armed forces' members.

    I've joined them in the challenge of creating a new outstanding product to help civil servants get a nice credit with an utterly easy process - using Next, React and styled-components.


  • Web Design

    Web Design

    Microcamp Tecnologia | 2011 - 2013

    At a local fair, I was given lots of discounts to start a course at Microcamp. At that time I still had no idea what career to pursue, and I liked the name Web Design; so I decided to take this course.

    In this course I had my first contact with technology and development. There I learned HTML, CSS and JavaScript (jQuery actually), I learned to work with design softwares (at the time, CorelDraw and Photoshop), I learned to make websites with Flash, and I also had a brief introduction to PHP.

    When I finished the course, I was still finishing high school and already had decided what I wanted to do with my life - work with software development.

  • IT Management - graduation

    IT Management - graduation

    Faculdades Santa Cruz | 2014 - 2016

    My uncle and my cousin took this graduation, and they highly recommended the course. I was in doubt between doing this or going with Information Systems course. The great advantage of this course was that the level of graduation was "technologist", and the duration was shorter - 2.5 years.

    In this course I had contact with C development, people and resource management, database management, strategic planning and entrepreneurship.

  • IoT and Embededd Systems - post-graduation

    IoT and Embededd Systems - post-graduation

    Universidade Positivo | 2017 - 2019

    Right after graduating, I didn't want to stop and threw myself headlong into graduate school. I was immersed in the bubble of web development, and literally wanted to get out of the box and learn something totally different.

    In this course I had contact with C, PHP, Android (Java) development, cloud servers development and management, electronic prototyping (using Arduino, Raspberry and Tiva C), artificial intelligence using IBM Watson, big data and development for smart cities.


Since 2018 I’ve started to write and speak about technology, development culture and career; from tips, tutorials to reviews and opinions. Also, started to speak about those topics in meet-ups and technology events. You can find my articles on my Medium, dev.to and my personal blog.

Besides speaking, I’m also working as a volunteer tutor and mentor. In 2019 and 2020 I was invited by Gama Academy to teach about front-end development in their Gama XP, a program which help people to develop their abilities on development, design, sales and marketing.

In the last years I've been trying to contribute with the community - that's why I do open source. And open source is also a nice way to learn new stuff! You can take a look at my open source projects on jlozovei.github.io.
