# Jonathan Ullberg > Senior Software Engineer at Expedia Group Location: Snohomish, Washington, United States Profile: https://flows.cv/jonathanullberg I am a software engineer who builds clean, modular code and responds to business needs with software solutions. I have a few things I'm passionate about. Solve Problems Scalably - I look to learn problem spaces deeply and come up with solutions that can scale. Although I focus mostly on front-end and JavaScript technologies, dev-tooling, and deployment, I'll get my hands dirty in anything and ask dumb questions to make sure I understand a problem space and can solve the customer's needs. Educate Well - I raise the bar for those around me and look to help my teammates get that "aha" moment through teaching, training, education, and collaboration. I try to use creative techniques to make sure no developer is left behind in understanding a technical problem. Build an Inclusive Culture - I believe that our teams and our software are better when we get a large set of experiences, backgrounds, viewpoints, and perspectives. Because of that, I look to ask open questions, engage everyone, and challenge the status quo to make sure everyone is able to be heard. ## Work Experience ### Senior Software Engineer @ Expedia Group Jan 2021 – Present | Seattle, Washington, United States ### Software Engineer @ Expedia Group Jan 2016 – Present | Seattle, Washington, United States - Technologies: JavaScript, Java, HTML/CSS, AWS, Cloud, Docker, jQuery, Node, ExpressJS - Developed customer facing features that drove conversion and revenue goals - Completed complex projects - Designed large scale systems - Drove teams to produce results - Mentored junior engineers, interns, and new hires. - Taught technical classes for teams within company to encourage shared knowledge and growth - Worked closely with technical and non-technical employees to drive results - Demonstrations and presentations to executives and directors on a regular basis - Improved quality control processes for teams ### Front-End Developer @ zCrowd Jan 2015 – Jan 2016 At zCrowd I was responsible for transforming existing front-end applications into React applications and standardizing build tools, testing and deployment for the front-end development of the company.
