    I’m a Mechatronic Engineer who was attracted to the dark side of software development early in my career. I have real-world work experience with some of the most popular software development technologies (full list at the bottom). I always take the time to understand the business and technical aspects of your project before writing any code, but still just charging you for development time only. That gives you the confident that you will only pay for code that actually works, pushing your project in the right direction on every release. I'm not the typical dumb Code! Code! Code! programmer. I have worked as software developer since 2006, and here in Upwork (former Odesk) since 2012. Upwork projects are what put food on my table so you can expect full dedication and fast response time. I'm always online on normal office hours, Monday-Saturday. My time zone is GMT-5 (same as NY) all year long. Here is the list of technologies I have worked with: On going (Back-end Developer) Vagrant, RESTful From 2018 to 2020 (Java web development) Spring Boot, JSF, PrimeFaces, JAXB, JAX-RS, SQL Server 2008 From 2017 to 2018 (Javascript mobile) Node.js, express, React Native, IOS, Xcode, Blockchain From 2013 to 2017 (PHP Web developer) PHP 5, MySQL, Laravel, Lumen, AWS EC2, AWS RDS, AWS Codepipeline, AWS Elastic Beanstalk, cloud 9 IDE, Github, bitbucket.

    I love computers, my technical skills are good but my soft skills are my strenght because of the following reason Felling always curious and hungry for knowledge allows me to listen much more than I talk, understanding what is our goal, our struggles and our main routes allows me to talk to my colleges and think solutions that perhaps are not the best at the start but are in the way to foster long term relationships, solutions and products that people loves Technically speaking my major field of expertise is the infrastructure, backend and middleware layer, although I feel a great amount of interest for the frontend development. I feel sad with code that is not easily understandable by my colleges, so I strive to create code that everybody can read and understand. I also like sharing what I know and my personal experiences with my collegues, so I feel also particularly fun of creating documentation and setting standards, like naming conventions and defining processes My weakness Its very hard for me to leave a problem without a solution, so I often see myself working extra time
