About Me

Helo, I’m Denes Papp!
I am a freelancer full stack web application developer with 9 years of experience in web development. My favorite frameworks are Symfony (backend) and Angular (frontend) but I also use Ruby on Rails and Django. I'm building fast, interactive and scalable web applications using REST APIs, strong design patterns and PAAS providers (AWS, Google Cloud, Azure). I mainly work for US based companies who find and hire me, but I have experience working with corporations from the EU too. I love travelling, already visited 25 countries and the list is constantly growing. In my free time I do Krav maga, Crossfit and running. Feel free to contact me :)

MoocNation was a MOOC (Massive Open Online Course) aggregator platform with thousands of online courses and a social platform for students to collaborate and share study materials. The project was designed as a singlepage-application where the frontend has most of the application logic (including templating, routing, etc.) and only uses the backend server through a RESTful API. The MoocNation project involved dozens of important 3rd party tools and API integrations.
