Full-stack developer with RoR experience from 2007 and web-development experience since 2000.
I can provide you with mentoring on all stages of your project from requirements gathering to deploy.
I am committed to provide excellent mentorship and solve issues in the most efficient manner. I am a freak, who will create a high-quality, simple (in terms of usability and maintainability) app for mobile, web or desktop for you. Or smoothly solve the errors you are running into. It's up to you.
I started programming with the Java language. I was writing desktop applications.
Next, I added PHP to the stack with Laravel framework.
Next, I picked up Ruby on Rails and loved it ever since. I have done a couple of projects (personal, open source and for organizations with teams). I have worked with Javascript and some of its libraries (React, Node, jQuery).
I am good with git and version control and feel very confident approaching every merge conflict I encounter.
Aside coding, I like listening to cool music, watching movies and tweaking the settings/preferences of tools I use. My favorite part of every application is the customization section. I also like artistic and creative works.
Developer with over 10 years of work experience. I primarily deal with application security and full-stack develoment. Extremely proficient with PostgreSQL, Golang, and reverse engineering/application security for a quick consult.
Web Developer in a wide variety of business applications. I mentored people on the site a while ago, coming back now with more experience in my belt and happy to help in a variety of domains and languages.
