Hi

I'm David Sharek and this is a glimpse into my professional career as a user experience practitioner.

My mission is to uncomplicate the life we have designed. It doesn’t matter if it is software, hardware, or a even a business process, I use my understanding of humans and technology in order to break down and then rebuild new or existing things to be easier and more valuable to use.

More specifically, I am obsessed with behavioral design for positive change. I think the ability to design products and systems that positively influence how we act and live is one of the most rewarding endeavors. For me, it’s more than a job, it’s why I’m here.

With Rompn, I am exploring ways to easily broadcast and digest location-specific information in real-time. One of the interesting things that I've discovered is that by allowing people to add an emotional valence to their messages, people are more likely to stay engaged in the app and search for other locations that are either "happy" or "unhappy".

This is an ongoing solo project.

UX.guide is a public, User Experience, Slack community with over 1400 members. It exists to provide a collection of useful information for people interested in User Experience, Product Design, and the general art and science of improving the human condition through making things of value.

I created UX.guide for a few reasons. I was interested in exploring alternative approaches to online community building, and the idea of "hacking" Slack for this purpose was appealing. The other driving reason was that I wanted to connect with other UX practioners as well as help those just getting started.

This is an ongoing solo project.

I'm currently re-designing my online version of the NASA-TLX, a subjective, multidimensional workload assessment tool. I built the first version back in 2006 using Flash and it probably goes without saying that it's time for a major overhaul! However, despite the outdated design the requirement of the Flash plugin, it is still being used daily by thousands of researchers worldwide.

The NASA-TLX rates perceived workload on six different scales: Mental Demand, Physical Demand, Temporal Demand, Performance, Effort, and Frustration. It was originally developed by the Human Performance Group at NASA Ames Research Center over three years and more than 40 laboratory simulations, and is thought to be one of the most validated workload measurement tools in Human Factors Psychology and Engineering.

I created the online version of the TLX because I needed it for some research I was conducting at NCSU. After I built it, I realized it would be useful for other researchers so I decided to release it to the public.

This is an ongoing solo project.
