I am a software engineer, I like developing high scale and creative software based on modern technologies, I am an expert in JavaScript especially Node.js for server side. React, Redux, Relay, Angular, for front side and MongoDB as DBS. I am doing data analysis (scraping data, web data analytics) and security assessment (OWASP Testing Guide, OWASP Review Code Guide, OWASP Top-10, OWASP ASVS), as a freelance consultant. My care is to develop wonderful secure software applications, keeping using the best practices to respond in the best way to the business needs.

The language I am currently most fluent in, is JavaScript for both client and server development, although I have done work with Java, C++, and Python. I am most passionate to work with Node.js to create web apps and APIs.


I am most comfortable with agile development processes and enjoy pair-programming and practicing TDD and BDD.
