@juliankunzig
Senior software engineer improving e-commerce performance with scalable front-end systems.
What I'm looking for
I’m a senior software engineer with more than 12 years of experience designing desktop and web applications using Object-Oriented languages. I bring a get-it-done, on-time spirit, and I focus on good programming practices, troubleshooting, and continuous learning.
Most recently, I’ve led the development of a high-traffic e-commerce platform, improving site performance by 30% and increasing user engagement by 25% through intuitive UI/UX collaboration. I also enhanced development velocity by 20% using a scalable front-end architecture and reusable React components.
Across my career, I’ve built solutions with React/Redux/Next.js and Node.js, integrated RESTful and GraphQL APIs, and delivered interactive, real-time dashboards for decision-making. I’ve also supported cloud-based systems (AWS/GCP/Azure) and applied DevOps best practices with Docker and Kubernetes to improve scalability, reliability, and security.
