ABOUT ME
Sr. Front-End Developer
Sr. Front-End Developer
Hi, I'm Julian. I'm a Software Engineer based in Buenos Aires, Argentina.
My career has had a focus in front-end development, using the latest technologies like React and Redux, HTML5 and CSS3. I also have experience working with backend frameworks including Ruby on Rails and NodeJS.
I love to learn and teach, and years ago I worked as a Teaching Assistant during my time in college.
I'm fascinated with functional programming, in languages like Haskell, Elm, and PureScript, so if you're interested in that, don't doubt to contact me.
I speak fluent english and spanish, and intermediate french.

JavaScript is the language I use the most, and most of the projects I've worked on used it either on the front-end or the back-end.
During the last years, I've used frameworks like React and Vue on the front-end, and libraries like Express on the back-end, using advanced language features like async/await, iterators, arrow functions, and functional programming techniques, and I can teach you how any of those work.

Haskell is the purely functional programming language by excellence. I've used it for about 3 years now to create fast and correct back-end servers.
I use concepts like functors, monads, typeclasses and recursion daily, and would love to tell you about them.

Julian was able to help me with the specific freelance job work that I created. He really has a good knowledge of the subject - Blockchain and Cryptocurrency. Had a great experience working with him and delivered the work right on time, even when the deadline was short. He provided a great customer service where he resolved a situation in a very short time and handled it in a correct manner. He will go a long way on this portal! Thank you, Julian.! Highly Recommended!!
