Summary
👤
Senior🎓
Top SchoolKarl Keller is a motivated full-stack developer with 11 years of IT experience who specializes in Ruby on Rails and prefers dynamic languages, currently re-entering the software market after formal full-stack training at Le Wagon. He combines practical backend experience (Python/Django, PostgreSQL) and front-end JavaScript with a strong autodidactic drive—actively learning Docker, functional programming, HTMX-style HTML-over-the-wire, and practicing TDD. His background spans apprenticeships and hands-on roles from support and on-site installations to software development and teaching assistance, giving him a pragmatic, user-focused approach to building reliable web applications. Based in Mindelheim, Bavaria, he balances development work with nontraditional gigs (currently driving for a taxi venture), reflecting adaptability and discipline outside the typical tech career path.
