Martin Kozmelj
Senior frontend developer at Sportradar
I am creating seamless digital experiences with a passion for the latest web innovations.
Summary
Experienced in crafting dynamic user interfaces, I specialize in React, but also fluent in Angular and Nest.js. From single-page applications to intricate full-stack solutions, I stay on the cutting edge of technology to deliver modern digital experiences.
Starting my carrer in a 10-person company and then move to a corporation of 4,000+, I've thrived in diverse team environments. I excel in fostering efficient workflows and impactful results. My adaptability shines in both small, close-knit teams and large-scale projects.
Beyond coding, I'm fueled by sports and outdoor activities. Whether on the football and badminton court, or cycling and hiking trails, these pursuits not only invigorate my spirit but also contribute to a balanced and creative approach to both work and life.
Experiences
2022 - PRESENT
Senior Software Developer · Sportradar
In the first two years I worked as a frontend developer in a Mobile unit. The projects that I worked on were mostly admin dashboards for different settings that were used in mobile applications. I also took a part time position as a Scrum master to improve workflow on some of the projects.
I moved to another team in September 2024. There I started working on a moderation interface. I am always eager to help improving the workflows in all the teams I work. I am making suggestions all of the time and I can proudly say that most of them are not just taken into considerations but also included in the workflow.
