About Me

Some Things About Me

My name is Anderson Grüdtner Martins, I'm a 15+ years experienced Full Stack Developer, passionate for Jesus, my wife, classical piano, drawing and creating stuff.

Personal background

As personal life achievements, I could highlight: completed the technical course of classical piano, successfully built a machine using Arduino to trap homeless cats using a infra-red remote control - for rescuing them, and I have been teaching children at church and teaching music for adults as volunteer.

My hobbies: play the piano (maybe more than a hobby), digital drawing, Arduino and eletronics.

Some professional background

I started coding teaching myself in 2002, using Delphi 6. Worked as volunteer developing a desktop system for a church, until start working with PHP and online systems, in 2006. Since then I have been focusing on Web Development, but had the opportunity to work different skills.

I began my studies in Analysis and Development of Systems in 2003, when I faced the challenge of develop as the final individual project an algorithm interpreter for being used as learning tool. After extensive researches and analyse process I was able to successfully implement a custom programing language using structured portuguese and an IDE with the objective of improve the programming learning process. My greatest accomplishment came in 2006, when my IDE was used as support tool for algorithm classes in two state universities: UEM - Universidade Estadual de Maringá, and UNIPAR - Universidade Paranaense

I led a small team of developers for about 6 years being responsible for the development of different projects, like an ERP system for Glass Industry, websites for many city conceals, an iPad app for the Clothing industry, and other projects. While being the lead developer I implemented a working prototype of a 3D web tool for auto-calculating measures and budget of projects on the Glass Industry. It was one of the most fun projects I ever worked. Learned a lot.

Over the years I had the opportunity to contribute to some Open Source projects including Joomla (was member of the JUX team when releasing Joomla 3), Choosen and Ajax-Typeahead.

For about 7 years I have been focused on developing Joomla extensions and WordPress plugins used by thousands of hobbyists and professionals.

Working on very different projects I had the opportunity to develop different skills: programming, systems analyses, linux servers installation and management, backend development, project management, SQL and noSQL databases, web services and APIs development, mobile apps and others. All that skill set works as a great base for learning new technologies, or for developing solutions for different problems.
