ABOUT ME

Senior full-stack developer with 15+ yrs shipping web apps

👋 Hi, I’m Marcos! I’m a full-stack developer with 15+ years of experience building web applications, leading teams, and solving tricky technical problems. Over the years, I’ve discovered that what I enjoy most is helping people grow — whether that’s through teaching at coding bootcamps, mentoring beginners online, or running workshops for fellow developers.

My approach is very hands-on and didactic: I like breaking down complex concepts into clear, practical steps and guiding people until the “aha!” moment clicks. Many of my past mentees and students have gone on to land their first jobs in tech, and seeing that transformation is what drives me.

If you’re looking for a mentor who’s approachable, patient, and genuinely invested in your learning journey, I’d be happy to support you.

After spending years experimenting with functional programming, I finally joined a company that used one as its first choice. Since then, I've implemented several crucial features and helped maintain complexity in a product that is a commercial success. ReScript is a very robust language that makes modeling data and workflows a breeze, while keeping interactions with JavaScript simple trivial to implement. It's also an excellent match to work with React due to its unidirectional nature.

JavaScript is everywhere, and for good reason. I've been using JS and languages that compile to JS for several years now, both in the frontend and in the backend. Having worked in multiple projects of varying complexity, handling async workflows and memory management, I'm capable of solving difficult issues and implementing maintainable systems.

I started learning Ruby not only because I wanted to develop Ruby on Rails applications, but mainly because I was looking for a language in which I'd feel comfortable with. I've tried Perl, then Python, and finally fell in love with Ruby's expressiveness, flexibility and readability. I was amazed by the mixed functional and object-oriented programming aspects, allowing me to achieve complex computations in a way I had never been capable of. Besides that, the Ruby community captivated me from the start as well, with its highly active (and well structured) projects, forums and mailing lists, as well as the culturally encouraged focus on automated testing and TDD. Since then, almost all my serious projects were Ruby-based.

I've been working with Ruby on Rails since 2010. At the beginning, I've worked on many internal projects, freelances and academic works, but since December 2012 I've been in the startups' world, working on successful projects like Posto Zero (http://postozero.com/) and oritmo (http://oritmo.com/). Currently, I'm developing an education technology application, Dunno (http://beta.dunnoapp.com/).

Although I have been working with web development for 5 years, it was in 2013, when I got my job in a startup that demanded pixel-perfect implementations of mockups, that I really started learning how to write HTML and CSS with intent. I've been also experimenting with HTML5 and CSS3 features extensively, incorporating them as they're supported by the most used browsers.

After using SVN and even CVS for a while, I finally started using git in 2010, and I can say for sure that it was one of my best decisions. Its distributed approach makes it dead simple to link several repositories on custom basis, and its incredible toolset allows you to do pretty much anything. On the other hand, great power comes with great responsibility. It's pretty easy to mess things up, so you need to be careful when typing commands. Nowadays, I recommend to anyone to install git-town (http://www.git-town.com/), which adds some very powerful, but safe, commands, that automate several common tasks in a regular workflow.

I've maintained and developed new features for a training-focused LMS at a fast-growing startup, thriving in a competitive market with an innovative product and a B2B business model. Among my responsibilities I designed efficient and flexible solutions, drafted proof of concepts for new ideas, maintained multiple codebases and helped cultivate a culture of excellency through code reviews and constant communication. Some of the high-impact features I recently worked on were:

Single-handedly implemented SSO using the SAML protocol, both as Identity Provider and Service Provider, which facilitates access for our clients' users.
Designed and implemented a highly efficient and flexible reports system, allowing clients to access up-to-date custom data visualizations.
Added and documented several endpoints into our client API, making it possible for our clients to automate time-consuming tasks.
