    I'm a full-stack web developer looking for opportunities to work with Elixir. Check my Full Stack Dev profile for a better insight into that. As a full-stack dev I'm comfortable working parts of the front-end, CSS/SCSS, I have experience with VueJS, Nuxt, React, Gatsby, used jQuery and Rails (in the past) and templating languages such as SLIM, HAML, Pug. I'm a hands-on person, and like to design systems, I've done several projects in different areas and I enjoy the process of translating ideas into functional software. I can develop an MVP for a fixed price if given a reasonably detailed specification. I'm Portuguese, I've done my high-school with incidence in Computer Technologies although I later on went to university in a completely unrelated field, Photography, which I concluded with above average grades and some exhibitions in my curriculum. That's why you'll find many of my job history under this profile to be related to image editing. I'm used to working online across slack, email, asana, trello, upwork, video&voice calls, although I don't do video/phone calls before a project is in place and funded with a clear deliverable agreed upfront. Afterwards, but depending on the extent of the project, weekly to bi-weekly meetings are ok. My timezone varies but I have always been able to find working solutions when needed. Looking forward to new projects.

At A Glance: Erlang

There are hundreds of different programming languages that have been developed throughout the years, with each language focusing on and solving different problems, challenges, and difficulties in the world of programming and computer science. One available language you have access to is Erlang, a general purpose programming language that has been supported since its release in 1986 and is now open-source. Erlang’s claim to fame in the crowded programming world is its suitability for building always-available real-time systems that are massively scalable. Those values specifically appeal to businesses in the telecom, banking, eCommerce, and instant messaging fields.

Erlang specialists are skilled in the intricacies of the Erlang programming language, and as such are capable of providing you and your business with a variety of valuable services. If you are looking to develop programs and applications from scratch, an Erlang specialist can help guide you through the process and benefits of using the Erlang language. Erlang specialists can also direct their knowledge and experience toward modifying, updating, or debugging current applications or software your company may be using. They can even tailor new interfaces to leverage features from other programming languages. By nature, freelance Erlang specialists and programmers are typically available to look at and work on smaller sections of code in a piecemeal fashion, when needed, thus providing a cost-effective way to manage Erlang-written software without investing too much valuable time and resources. And as with any Upwork freelancer, you gain the flexibility of partnering with talent based anywhere in the world.
