WORK HISTORY
Senior Product Manager @1KOMMA5°
Munich, DE
At 1KOMMA5°, I lead the development of intelligent energy products that connect dynamic pricing, household flexibility, and real-time market signals. My focus is on scaling complex energy systems into usable, customer-centric software solutions across Europe.• Built one of the first fully dynamic electricity tariffs in Germany, combining real-time pricing and load shifting, enabling some of the lowest residential electricity prices, often close to 0 ct/kWh.• Scaled the product to thousands of customers and launched it in four European markets, adapting to regulation, infrastructure, and customer behavior.• Led cross-functional product strategy, aligning long-term company mission with short-term team priorities through structured discovery and collaborative planning.• Introduced Shape Up and async-first work practices, replacing Scrum to reduce meeting overhead and increase team responsibility in product discovery and delivery.• Drove data and process stability initiatives across forecasting, optimization and trading, ensuring reliable cross-team execution in a complex energy system.
