Hello there! It's nice to meet you!

I'm Ruben Serrate, a full stack Javascript developer currently based in Barcelona, Spain. However, I've lived in the UK for over 4 years so I'm profficient in English.

I've got more than 10 years of experience as a Javascript engineer. Academically, I completed a Computer Engineering MSc, so I feel comfortable in most programming languages, but my selling point is definitely Javascript, both in the back end, as NodeJs and in the frontend, particularly with React.

I also feel comfortable managing AWS environments, specifically, I've taken a keen interest on serverless applications lately.

I currently have a remote full time job @Emax digital, so I probably won't be open to new opportunities, but feel free to get in touch using the contact form.

Javascript

I've used it daily for +10 years now. In the frontend, I've got plenty of experience with React (usually used with redux and Rxjs) and Vanilla JS.
In the backend, I'm fully comfortable around the NodeJS ecosystem, as I've also been working with it for a very long time.

TESTING

Fully familiar with unit testing, integration testing and end to end. Usually apply TDD even to my personal dev work. Mostly Jest and Mocha as test frameworks, and Selenium webdriver for e2e.

MongoDB

In touch with it for almost as long as I've been using NodeJS, fully familiar with it and able to use it efficiently. Indexes, aggregations, etc.

HTML5 & CSS / SASS

I’ve been writing HTML and CSS since I was a child, and used it for work since I started my career. I use SASS as a pre-processor and I'm fully familiar with CSS3, HTML5 and most SEO best practises.

AWS

I've been hosting small websites and services on AWS for about 5 years. Recently, I've been moving most of my applications to serverless technologies so I've gained quite a lot of experience with services such as Lambda, DynamoDB, API Gateway, S3 …

AGILE METHODOLOGIES

Following agile practices pretty much since I joined the industry. I've used all sorts of variations of Kamban, SCRUM and pair programming. Also familiar with JIRA.

LAMP STACK

I started my career as a PHP and MySQL developer, so I do have some knowledge and experience, although frankly, I'm a lot happier working with Javascript and MERN stacks.

WordPress & MODx CMS

Also remnants from my past as a PHP developers, I developed heavily in these two CMS for 3 years.

C# & ASP.NET

Used it extensively at University. Chose it for my final year project (a HTML5 multiplayer poker server and web interphase). I haven't used it commercially. In fairness my .NET knowledge might be out of date now, but I still use daily some of the patterns I learnt with it.
