With over 15 years of professional experience, I have honed my skills in back-end and full-stack development, specialising in creating robust, user-centric software solutions that meet and often surpass expectations.From migrating critical systems from OpenShift to Kubernetes—a move that reduced annual infrastructure costs by about $100K—to developing integral components of Sweden's largest e-health platform, 1177.se, my career has been a series of challenging yet rewarding milestones. At 1177.se, I was pivotal in boosting the system's reliability and scalability, enabling seamless 24/7 operations that now support over 10 million Swedish citizens, reflecting a 1000% growth in user engagement.Key accomplishments include:🌟 Led a team that revamped Sweden's digital healthcare landscape through the 1177.se platform, bolstering capabilities of the system to manage enormous amounts of health-related tasks for millions of users.🌟 Innovated security measures for a Swedish county, which involved rewriting critical server certificate store handler code. This improvement was later recognised by IBM for its efficacy, enabling the county to serve 50,000 citizens.🌟 Spearheaded the seamless transition of system architecture from OpenShift to Kubernetes, which maintained high reliability and performance and cut down on costs, demonstrating my commitment to cost-effective technology solutions.Professionally, I've taken on diverse roles ranging from a full-stack developer for Telia Company AB, where I currently enhance checkout flows and integrate cutting-edge technologies like React 18 and AWS, to being a senior software engineer at Burp Empire AB. Here, I led the development of various high-performance applications and fostered an environment conducive to Agile methodologies, ensuring rapid delivery of high-quality software.In every role, I leverage an expansive skill set that includes expertise in Elixir, React, Node.js, and cloud services, focusing on microservices architecture, RESTful API development, and continuous integration/continuous deployment (CI/CD) practices. My approach is always holistic—balancing innovation with user satisfaction, system security, and operational efficiency.As I continue to evolve and adapt to the ever-changing landscape of technology, my goal remains clear: to develop software solutions that are technically proficient and aligned with business goals and the latest technological trends. This mindset has shaped my career and the digital experiences of millions of users worldwide.Let’s connect!
