Peter Bittner is a seasoned Python developer, DevOps engineer, and Continuous Delivery coach with 14+ years of experience building reliable Django-based products and delivery pipelines from Switzerland. As co‑founder of Painless Software and former CTO of Organice.io and Lawbrary.ch, he blends hands‑on backend development with strategic coaching to make software development a "no‑surprise" business. He has modernized deployment and automation practices across banks and enterprise firms (UBS, Julius Baer, Migros Bank) and helped teams adopt CI/CD, IaC and test-driven workflows. An active open-source contributor and documentation specialist in well-known Django projects (pytest-django, django-allauth, django-configurations, behave), he focuses on clarity, code quality and practical integrations. Colleagues know him as a perfectionist with deadlines—someone who pairs pragmatic engineering with an eye for usability from his Certified Usability Analyst training. He’s equally comfortable refactoring backend logic, improving developer experience, and coaching teams to ship continuously.
