Consulting, Coaching, Training

Due to extensive work in academia and research projects for industry clients, I can offer consulting on semantic technologies , artificial intelligence and machine learning and, innovation projects, as well as software engineering and knowledge management.

🕸 Semantic Technologies

Connect data sources, infer new insights, query aggregated knowledge, lift unstructured data, formalize, manage meta-data, define a common schema — faster when I am part of the project.

Experiences:

  • Linked open data: Co-author of Cool URIs for the Semantic Web, W3C); creator of open-source tools for working with RDF and Java (RDF2Go, RDFReactor)

  • Wikis: Co-inventor of Semantic MediaWiki, industry projects, wrote custom wiki engines

🤖 Artificial Intelligence

Which AI technology can or should be used to increase customer satisfaction and lower costs?

My computer science masters topics: neural networks, fuzzy logic, clustering, data mining, information theory, decision trees, reinforcement learning, simulated annealing, genetic programming

💸 Innovation and Business Models

After studies in entrepreneurship, several own start-ups and career as Lean Startup trainer, I’ve seen, analyzed and optimized countless business models. My special focus is on risk reduction and validation of information in early stages of an innovation project. Methods: Customer Discovery, Problem validation, Solution validation, Product/Market-fit, metrics, business model canvas

Experiences: gave numerous invited and paid talks since 2011 (e.g. KIT Venture Fest 2014), seminars (3+ years at EnTechnon), trainings (e.g. KIT upCAT Accelerator 2015, 2016, 2018)

👓 Software Engineering

During my time at university and my start-ups, I held several internal trainings on software engineering (e.g. onboarding of new engineers with Java, Eclipse, Maven, Git). I can also help you evaluating and selecting the right open source libraries for a given tasks, since I had to do that hundreds of times.

🦉 Knowledge Management

Which tools and processes increase productivity of your knowledge workers? You need a pragmatic analysis of the current state and the next step for improving the status quo. Often seemingly simple IT tools or process changes can unlock the best return on investment.

Experiences: Dissertation on Persönliches Wissensmanagement mit Semantischen Technologien, industry projects
