What application development/support skills would you recommend for someone trying to advance their career?

Ali Alouani

Professor of ECE

Be confident, work hard, and have good communication skill.

What technical skills for an application development/support stand out to employers?

Janos Fustos Ph.D.

Professor, Metropolitan State University of Denver

These days - since we went to the home office - everybody is looking for solutions that gives more and better support to remote workers. Organizations are looking for options where they can connect back to the organizations'' networks to complete their work. But that means much more work for the IT folks to make that happen and do that safely and securely. That means they are looking for individuals with technical skills that are in or closely related fields: security engineers and analysts, business analysts, data administrators, cloud service operators, network specialists etc.

Also, employers are looking for more experienced professional who can hit the ground running because their needs are more pressing and immediate, so they do not have too much time for training and education. But they are also looking for trainers to better educate users about their working environments and the changing working conditions. Users have to rely a bit more on these trainings because they cannot enjoy the immediate and direct IT support in their homes. In addition to that (or to extend that) helpdesk people are also in high demand who have the technical and also the people's skills to troubleshoot the problems that occur in highly uncertain and diverse environments.

What hard/technical skills are most important for application development/supports?

Travis Mandel Ph.D.

Assistant Professor, University of Hawaii at Hilo

Being comfortable with refactoring code is definitely one of the big ones here. Absolutely no one writes perfect code right off the bat - a good software engineer should recognize that and always be open and receptive to suggestions about improving their code. Even in the absence of such suggestions, a software engineer must be able to independently recognize that "the tower is about to fall over"! Meaning, if the code is turning into a real mess, a good software engineer will be able to realize that and independently begin refactoring it into a better state, even if that takes time away from implementing new features.

Another one I'll mention briefly is designing class inheritance diagrams to solve a new problem. The right structure here can allow components to be easily re-used and extended. But the wrong structure can lead to disastrous consequences, so it requires a lot of thought about how things will likely evolve in the future.
