Expert 10x | Software Developer | UX Designer

Hi! My name is Mark Tellez and I am a web developer who can work on the back end, front end, and anything in between.

I love JavaScript and React, functional programming, and good UX design.

I have been coding professionally since 1997! I started in C, moved onto the web, learned and used every imagineable language of the times, and learned to love JavaScript more and more.

I have had the enormous privilage to lend my skills to companies like PayPal, Intel, UpperDeck, GEICO, and many more.

Along the way I have refined my coding habits and techniques to include, and be built around dynanisism and functional programming. What many of your engineers will take 50 lines to do, I can do it in 20 readable lines.

In the last couple of years I have worked with doezens of clients, and I have yet to find something I couldn't impement using my tools and skills. I have great communication skills, and my primary goal is to be reliable and predictable in my work.

But enough yappity yap, how about some examples?

I present you, the GitHub branch/tag selector

I think this is a great example of ui design to make the user's life just a litle bit easier, while at the same time, not require a lot of screen space.

I am using json as a data source, because, that is how you build React, the "right way". It makes your components less coupled to api and network changes, and ends up providing a better, more hexoganal design.

Or maybe a select box is more your speed?

This is how I would make a dropdown in 2022. It uses keyboard interaction, and can easily be adapted for use with a screen reader. The keyboard only tracks while the filter is focused.

This works with all pointer objects, not just the mouse!
