Fabricio M.

Vetted Spring Security developer in Brazil (UTC-3)

I have over 10 years of experience in web development, frontend, and backend with Java, Nodejs, PHP, JavaScript, database management systems, HTML, and CSS. I think the company where I learned more was the Instituto Atlântico, I spent a lot of years working there, and I had the opportunity to work with a bunch of different technologies and businesses, for companies in Brazil and around the world, it gave me a very sober vision about the development of systems and business world in general. There I could work at the back end, front end, and as a Team tech leader, so I believe that it was so important to my professional development. I worked on various projects and I always tried to give my best in all of them, but I can summarize some contributions that were very important to some of them. * Around 2015 the company I was working for won a prize in printer fair competitions in German, with the Print OS system when I was working on it, it was awesome at this time I was performing a very important role working in both front and back end and sometimes leading the frontend team. * In 2012 I worked on a set of systems for the electric energetic sector, and at that time, I solved a huge problem of performance that made them spend a lot of time generating the billing data for their customers, there were a lot of bottlenecks in the process but the major of them was a legacy query in an Oracle 11g database that used to take about 3h to run. after a long analysis, I was able to create some mechanisms to reduce this run time, by creating some materialized views, re-indexing lots of tables, and caching some data that use to come from DB links. in the end, I could achieve an execution time between 3 minutes and 15 minutes. * More recently I did a change in a legacy API and I could reduce the number of requests to our customer's API from around 65k to at most 2k a day, this amount of calls was breaking down their API, which was not designed to receive this amount of calls, I did this refactoring using a cache strategy with Redis and Spring. My colleagues use to say that I have strong leadership skills, and I know how to share knowlegment about technology and programming.
