# Mitchell Sides > Senior Software Engineer Location: Spring, Texas, United States Profile: https://flows.cv/mitchellsides I'm a senior software engineer with a background as a professional athlete, high school teacher, and endurance coach. Currently, I specialize in: React.js, HTML5/CSS3, Node.js, full stack web development, software engineering, written communication, and leadership. I’m continually excited by how much fun it is to learn and I’m always open to diving in deep with new languages and technologies. As a coach, I coached endurance athletes with Source Endurance using cutting edge analytics and data-based tools. As a software developer, I value software that simply works and my aim is to write clean, organized, and efficient code that gets the job done, whether complex or simple. I fell in love with coding almost on accident, but I now can’t imagine working in any other field. Prior to writing my own code, I used advanced analytical software such as WKO4 and Golden Cheetah (and often good old fashioned Excel) to analyze, predict, and model performance in multiple domains. I quantified performance for my athletes and students, and then optimized my strategies for their improvement, and my own, based on data analysis. After a short time, I saw potential for better use of the mountains of data and I’m extremely excited to be part of the future of performance data and software development on the whole. I’d love to connect and talk about anything and everything, especially software languages and frameworks, cycling, swimming, running, triathlon, endurance sports in general, mountains, my brilliant wife, Lydia, Labrador retrievers, and pizza. ## Work Experience ### Senior Software Engineer @ TrainerRoad Jan 2023 – Jan 2025 | The Woodlands, Texas, United States Experienced Senior Software Engineer with proven expertise in cross-platform development across web, mobile, and desktop applications.
