LoveMondays São Paulo, SP, Brazil

LoveMondays is the biggest platform of its kind in LATAM. Its purpose is to bring transparency to the job market by empowering employees to anonymously rate and review their employers, also letting them find out more about jobs, salaries and ratings at other companies. Glassdoor acquired LoveMondays in 2016 and since then the company became their official representative in Brazil, Mexico and Argentina.

Here I was member of the company's product team. My main technical responsibilities included mentoring less experienced teammates, shipping new features, helping the team with technical decisions and delivering useful and legible code in a reasonable amount of time.

The non-technical aspects included emotionally supporting the team through stressful periods, assessing and interviewing candidates for positions in the team and bringing innovation through new ideas and technologies.

Main Technologies: Rails, Docker, PostgreSQL, ElasticSearch

Middle Software Developer August 2012 - August 2016
DTM - Deliverying Technology that Matters Rio de Janeiro, RJ, Brazil

DTM is a software boutique that since its foundation has made several different projects for medium and large companies such as Vivo, Technip, Supergasbras and many other ones. Around 2014 it became one of the main Salesforce partners in Brazil, a parternship that brought even more important projects and customers to the company.

While there I developed and maintained web, mobile and enterprise projects. Also brought new technologies such as AngularJS and Ionic 1; both had a huge positive impact in the team and along with Rails became one of the company's main technologies ever since.

Also handled the infrastructure of those projects, mainly with Heroku and AWS, working also with Postgres and Elasticsearch. In almost every project some kind of integration was necessary, so I did lots of them, especially with Salesforce and Oracle.

Finally while there I brought both Rails and Ionic meetups to be held at the company's office, which in turn helped attracting new talents and even some new clients.

Main Technologies: Rails, PL/SQL, Heroku, AngularJS, Ionic1, ElasticSearch, Oracle, Salesforce
