• Develop and maintain the Opper API, powering scalable LLM workflows.
• Built Agent SDKs in Python and TypeScript for production LLM applications.
• Developed the AI Roundtable: multi-model deliberation as a product.
• Designed Taskbench, a real-world LLM benchmarking framework: curated evaluation datasets, a model-agnostic engine (plug-and-play via model string), and a library of evaluator types.
• Built Observer, a context-engineering agent that provides personalised observability across LLM interactions: auto-detects task intent, selects scorers, and improves calls via automated and user-driven in-context learning.
• Deployed autonomous agents in production environments.

Stockholm

• Led the technical development of a major pricing-optimisation programme.
• Designed ETL pipelines processing 50M+ rows and 100+ features.
• Trained price-sensitivity models with XGBoost, CatBoost, and LightGBM.
• Used clustering to identify behavioural segments for pricing strategy.
• Designed and ran A/B tests and price experiments, including custom monitoring tools and a price-simulation framework for scenario evaluation.
• Worked closely with pricing and commercial teams to turn insights into action.
