    Born in Vienna, Austria I was always math and technical driven. During high-school I discovered my passion for algorithms. I decided to study physics and by using my affinity to programming I specialized in numerical and computational physics. My Master thesis as well as my PhD thesis were written in English. After I finished my PhD I started to work in finance performing statistical analysis and developing automated trading algorithms. Since I was always more of an independent work type, I decided, along with 2 former colleagues, to start a business in IT-operations and consulting. However, I like diversity, new challenges and to learn new things regularly.

    Technology meets experience – since 1992. My journey into software development began in 1992 with BASIC – during my training at the Higher Technical College for Electronics and Communication Engineering, I expanded my skills to include Turbo Pascal, C, C++, Fortran, and Assembler. After several years in the industry, particularly in hardware-related development, I became self-employed in 2006 and shifted my focus to web and app development. What sets me apart: * Deep technical understanding – from code level to system architecture * Decades of experience in customer-oriented project implementation * High proficiency in PHP, JavaScript, Python, Flutter, and more * Extensive CMS and shop expertise (WordPress, Shopware, OXID, Joomla, etc.) * Routine with API integrations, interfaces, and accessible, responsive design What you can expect from me: I don’t deliver off-the-shelf solutions – I provide thoughtful, scalable, and maintainable systems that integrate seamlessly into your processes. Whether it's a CRM system, complex web shop, corporate website, or mobile app – my projects are technically sound and visually impressive. Team strength included: Together with my team of experienced backend and frontend developers, app specialists, UI/UX designers, and marketing professionals, we have completed over 400 projects – for companies of all sizes, often in close collaboration with agencies. Curious? I look forward to your inquiry – whether it’s for a new project, further development, or rescuing a stalled project. We’re ready.
