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.ElixirPhoenix Web FrameworkPhoenixLinux System AdministrationRESTful APIAPI DevelopmentJavaScriptDockerPostgreSQLPythonWeb ApplicationDjangoRuby on RailsRubyGolang - $60 hourly

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.
