Welcome
About me
Hi there, and welcome to my website!
I’m Lukas, a full-stack developer with a preference for backend development. With a background in IT security research at Graz University of Technology, I bring a wealth of expertise and experience to every project. While I have worked with various tech stacks, my favorite remains the Spring Framework. Recently, I’ve been focusing on LangChain AI development while also prototyping automations with n8n. Beyond hands-on development, I have experience leading teams and mentoring developers, ensuring smooth workflows and high-quality software.
I thrive on exploring new industries and technologies, constantly pushing beyond my comfort zone to learn from the best. Whether it’s optimizing existing systems or developing new software solutions, I approach every project with a practical mindset and a strong technical foundation.
If you’re looking for an experienced developer who can build reliable, efficient, and scalable software, let’s talk!
