Calum Hale • 黑楷荏


Calum is an end-to-end product designer who crafts data-driven digital experiences and custom software, most recently for data scientists and data engineers developing artificial intelligence + machine learning. Specialising in information design and data visualization, he produces user interfaces for digital products that enable users to easily understand complex data and achieve their goals.

His user-centred approach ensures features are researched, designed and delivered on time, using best practice agile methods. A certified Scrum Master with a deep product toolkit, he works in empowered product teams to deliver user value. Key skills include running user interviews/workshops, designing bespoke UI and working closely with engineers to ensure features work as designed.

An expert in creating delightful, user-centric digital experiences, he translates raw data into insightful visualizations to help users make sense of their data. Using his skills in typography, colour theory, grid systems and accessibility, he clearly conveys complex concepts to the user with pixel-perfect precision.

A native English speaker with experience in start-up, agency and corporate environments, he has led product and client teams while also managing and mentoring junior team members (both in-person and remotely).

In 2018 he joined specialist information design agency Beyond Words Studio where he led projects designing apps, websites, presentations, reports, animations and social media posts.

He was lead designer of digital products ‘Studio’ (a metadata management and visualization tool), ‘Diagrams’ (a tool for generating entity-relationship diagrams with code) and ‘Layer’ (a machine learning operations platform).

In 2023 Calum set-up his freelance design business, providing product design and UX/UI services to clients in the tech industry.
