Top SchoolTjark Petersen is a Senior Data Scientist and technical product leader based in Berlin with 12 years of experience building AI-driven solutions across startups and enterprise contexts. He combines hands-on machine learning engineering—ML pipelines, pricing models, demand forecasting and NLP—with product and CTO experience from founding a maritime AI startup focused on safer, more efficient operations. At AUTO1 and Marley Spoon he delivered production-ready models on cloud-native stacks (Python, Snowflake/Redshift, Airflow, AWS, Docker, Terraform) to optimize pricing, inventory and customer lifecycle. Earlier consulting at IBM sharpened his ability to translate stakeholder needs into proofs-of-concept and scalable implementations for regulated industries. Currently at paiqo he continues to blend product thinking with technical delivery, favoring pragmatic automation over academic complexity. Colleagues describe him as a builder who enjoys clean code and making data science directly accountable to business impact.
