Back to original languageAbout Oliver
15+ years of full-time web development, 25 years of technical experience
Having learned programming as a self-taught individual in my early youth, I became self-employed as a game developer in 2009 at the age of 22 while studying, founding Stonehill Games. Back then, the focus was still on game development, but over the years, the core business increasingly shifted towards web development. Stonehill Games was completely divested in 2014.
Since then, I have focused exclusively on web development, digitalization, and business web applications with Stonehill Media. With 12 years of experience as a self-employed developer and entrepreneur, I possess enormous know-how in project development, web development, and the latest technology, social media, and web trends. With over 100 successfully completed projects and renowned clients, I have built an impressive portfolio.
Furthermore, I am a co-founder of ticketareo GmbH, a platform that provides cloud software for marketing, planning, and executing events. I developed/programmed most of the software on this platform: AWS server infrastructure, backend, frontend, website editor, live streaming app, newsletter marketing tool, ticketing system, QR code ticket scanner, WebRTC video conferencing tool, AI automation.
