    I am an Elixir/Golang/Python/Ruby programmer and Linux System Administrator. I had spent 22 years in the corporate world as a developer and linux administrator, working in the office. 8 years ago I jump to working remotely from home as a freelance developer. I have built apps for my customers ranging from locally in Nueva Esparta, and all over the world. I take pride in my work and the majority of my customers bring me repeat business and referrals. I feel I have been successful, not just because of my web programming skills, but because I am a reliable and dependable web programmer that can be trusted to follow through with my work. I enjoy working directly with my clients, rather than having project managers involved. Even though I seldom meet my clients in person (due to geography), I am able to effectively communicate via email and chat to complete the website development project to their specifications.

    Hello, I am a web-development professional with 7+ years of experience(including 5 years of Ruby on Rails and 2 years of ReactJS) building and improving small to big live projects. Currently working with Elixir Phoenix projects and loving it a lot, especially LiveView. My core competency lies in the ability to jump into an existing project, read its code, and start delivering fixes, improvements and features without delay. As a professional, I want to be a reliable developer who will help you build a good product. I will hear what you need, evaluate it from different perspectives, based on my knowledge, then I will give you a feedback, we will clarify the task, and I will deliver what we agreed on. I do remember to keep a good balance between development speed, app performance and maintainability. Which means sane code cleaning, optimization or testing. I am striving to be reasonable, responsible and independent, with good emotional health and control. I am interested in a long-term collaboration, preferably part-time(to maintain good work-life balance). I am comfortable both solo and in a team. Currently I am in the GMT+3 timezone. Some of my interests: physical activity(walking, pong, badminton...), trekking, mindful scifi, chess, engineering, physics, biology and mind.

    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.

A Look at the Elixir Programming Language

It feels like a new language, library, or framework is popping up every day. It can be tough to keep up or to decide which is worth your time to learn and implement. But when the community-at-large rallies behind one of these new tools, it’s usually a sign it’s worth checking out—which is the case with the Elixir programming language.

Non-developers don’t always need to keep up with the latest programming trends, but sometimes it can be helpful to know the landscape, whether your team is developing new software from scratch, looking to improve performance with new modules, or working out a budget. Knowing what’s out there can be a good roadmap—especially when it comes to hiring developers skilled in those areas.

When it comes to general-purpose functional programming languages, there are plenty to choose from, each with their own strengths—Elixir may not have the near-ubiquitous presence of Python or PHP, but support for this six-year-old language within the dev community is growing. Its creator came from the Ruby on Rails team with the goal of creating a language with high concurrency and low-latency—your first tip to what Elixir (and an Elixir programmer) does best.

Elixir is dynamic

The goal was to take the best of both worlds from the Erlang and Clojure programming languages, so here’s where it resembles the dynamic Erlang. It’s high-level and executes at runtime.

Elixir is a functional programming language

What is functional programming (vs. procedural programming)? In short, it’s a style of programming (or, a paradigm) that focuses on using expressions to transform data in a way that’s simple, concurrency-safe, and without “side effects.” It’s like a math equation in that you’ll always get the expected result. It’s a tool suited for certain types of jobs, but not all. Elixir is an immutable functional language, which means that it’s easy to read and equally easy to build on (so no overhauls of code later on when it needs optimizing for more or bigger tasks).

Concurrency is the primary goal

Concurrency refers to how well a large number of processes can be run at the same time, independent of one another while mitigating side effects—and it’s the primary benefit of Elixir and its associated use of the Erlang virtual machine (EVM). Imagine a bank of elevators is your software. Without concurrency, only one elevator would be able to process a request to go to a floor at a time, which would hold up all the other people waiting for elevators. In software, concurrency processes multiple requests to the system in real time, keeping things organized and flowing. Furthermore, Elixir processes (not to be confused with OS processes) avoid issues associated with managing shared data and state across multiple processes, by ditching shared memory altogether and relying on asynchronous message passing instead.

Elixir is for scalable, maintainable applications

Elixir code is lightweight and easy to test, and its efficient use of machine resources makes vertical scaling easier to achieve. Also, the way processes can communicate with each other across the same network makes Elixir especially good for horizontal scaling.

Elixir runs on the EVM

The Erlang community has officially accepted Elixir, which was designed to run on the Erlang VM (or, “BEAM,” which is extremely well-suited for both distributed web development and embedded systems like the Internet of Things devices). This gives Elixir access to the Erlang ecosystem, functions, and the “battle-tested” benefits of its VM, which is good for:

  • Low-latency. You want to prioritize low latency when your software is processing a high volume of data that are constantly changing with real-time speed (so, not a lot of delay).
  • Distributed systems. We’ve discussed how virtualized servers distribute software horizontally across nodes; this VM provides a good foundation for that.
  • Fault-tolerance. When parts of software do go awry, supervisors within Elixir allow those parts of the software system to restart and get back to working order.

Why use Elixir?

Developers who use a language can always say it best, like an Elixir forum contributor who said: "chances are sooner or later you will have to do something web-related or distributed (even if you have one server with few cores) and that’s where Elixir shines."

More and more organizations are building distributed software—it’s more efficient, safer, reliable, has fewer dependencies, and fuels better use of machine resources. Rather than shoehorn old technologies into new models, using a modern language like Elixir allows developers to build distributed-style software from the foundation up.

And concurrency with low latency, if that’s a big priority for your software, is another draw—but you’re really talking about the benefits of BEAM and Elixir together. Another Elixir forum developer says “Elixir (and all BEAM languages) is great for building systems that may or may not be scaled out over several computers. That’s the purpose of working on the BEAM. If I […] wasn’t concerned about either easily handling concurrency or building systems, I’d choose something else.” So in short, what makes Elixir and other BEAM languages stand out is spreading big software systems over several nodes.
