About
Jonas Krauss
Full Stack Analytics Engineer
I'm a freelance analytics engineer specializing in predictive analytics for sales and marketing teams.
I help SMEs automate the analysis and forecasting of revenue, cashflow and customer funnels so they can make faster decisions and achieve more revenue with higher margins.
With over 15 years of experience in business intelligence, data warehousing and AI, I combine open-source components into complete solutions that solve specific business problems with clear, fast ROI.
Current Role
I currently lead the business intelligence team at CHI Cargo, where I built and operate a comprehensive BI system from the ground up.
As a freelancer, I've helped sales organizations transform thousands of inactive customer records into prioritized, high-conversion lead lists. I've built custom chatbots, recommendation engines and process automation systems that directly impact the bottom line.
