Software Developer

About me

I am a software developer in the search context. My main goal is to provide easy to run and maintainable software that does what it’s supposed to do. Therefore, I advocate test driven development and clean code in the team. My go to tools are Terraform, AWS, Github Actions and Python. I’m a fan of Clojure but my team hasn’t adopted it... yet.

    Part 3: Machine Learning Pipelines for Search: Learning to Rank

    In this article we will provide some insights into how we built the judgement pipeline, which is to serve as a basis for future LTR pipelines. What does a judgement pipeline do in the LTR context? It computes judgements based on user data for a certain timeframe. These judgements are to serve as the labels a ranking model will be trained on. Right now we also export these judgements for live validation on selected queries.
