About Me
I'm a Technical Lead with a deep passion for building innovative software solutions. With over 18+ years of experience, I specialize in creating scalable systems using modern technologies like React, Node.js, TypeScript, and cloud platforms. I love leading talented teams and fostering environments where developers can grow and deliver their best work.
My journey started in the manufacturing industry at Exoro System AB, where I developed software to optimize industrial machines and production lines. This foundation in Manufacturing Execution Systems (MES) gave me a unique perspective on bridging the gap between physical operations and software - something that still drives my approach to problem-solving today.
Currently at Volvo Group Connected Solutions, I lead development of systems that drive innovation in transportation and logistics. My career has taken me through diverse challenges: from building Sweden's largest print broker platform, to sustainable e-bike solutions at Zipforce, to global workforce optimization at IKEA.
Outside of work, I'm deeply curious about the AI revolution. I spend my weekends experimenting with LLMs, building RAG systems, and exploring how AI can enhance the developer experience. I believe we're at an exciting inflection point where AI will fundamentally change how we build software, and I want to be at the forefront of that transformation.
