We wish great success to Sérgio and to all the other developers who participated. Keep up the great work guys and keep being awesome.

In a short interview we were happy to get to know Sérgio a bit more and we want to share it with you too.

Tell us a bit about your career

I’m a Brazilian programmer focused on Front-end development. My career started 15 years ago and my first coding was in HTML. After that, came PHP and Java (at that time, if you want to be a “real programmer” you needed to focus on Back-end). With the advent of HTML5 and Front-end getting more attention, I refocused my career. Nowadays, I’m very passionate about HTML, CSS and JavaScript, specially mobile challenges, responsive web design and front-end performance.

What’s the future of responsive web design?

I strongly believe in responsive web design to solve the problems this new multi device world imposes. Some argue that a specific mobile experience is better than RWD. The problem today is now to define “mobile”. We have a wide range of devices and there are no clear lines to define device categories. If you try to draw this line, you will get it wrong and maybe exclude a lot of devices. I believe RWD (and its evolutions) is the only solution to target so many devices today and in the future.

What are the top 3 most referred resources or books you recommend to people?

My list is a very unstable one. I change it a lot. Today, I would recommend Mobile-first by Luke Wroblewski, High Performance Browser Networking by Ilya Grigorik and The Mobile Book by Smashing Magazine. I also recommend my book The Mobile Web, programming for a multi device world, which was initially release in Portuguese in Brazil and now is also available in English.

What are your 80/20 principles in business and life?

I think you should spend your time with things you are passionate about, that make you a better person. Both in business and life. Those moments should be at least 80% of your life.

What do you recommend to do if somebody wants to begin a career in front-end development?

To code a lot. You will only be good at this if you write a lot of code. You should study and read a lot of course, but I think practice is the most important factor.

What are your tools of choice, software?

A Mac with Sublime Text and Chrome Canary represents 90% of my time working. Other important softwares in my workflow include Pixelmator, ImageOptim, ImageAlpha and JPEGmini. For task automation I’m a huge grunt fan.

Who are your mentors & the people you admire in the industry?

My mentors are all the people that work in Caelum, where I work. I started here 10 years ago as an intern and learned a lot from everybody here since then. And I admire many people in our fantastic industry. To name a few: Brad Frost, Ilya Grigorik, Peter-Paul Koch, Luke Wroblewski.

What blogs do you read?

I read too many blogs (currently 250 feeds on my feedly account!). A few ones I read as soon as the author publishes something new. I love QuirksBlog, PerfPlanet (which aggregates great blogs about performance), MobileXWeb, Dev.Opera, HTML5Rocksgetblog, igvita, insouciant, A List Apart.

What are your long term personal and business plan?

I intend to work in my current company for many years to come. We are a education company in Brazil with programming training (I teach front-end and mobile), online classes and a book publisher. My plan is to help the company grow to new areas and continue improving IT education in Brazil. Personally, I will keep focusing on Web development. I love to write and want to write other books (already have published 3 books in Portuguese and 1 in English).

We want to thank Sèrgio again and everybody who took part of the Javascript quiz.
