Meet the author

Ondřej Chrastina is a seasoned Developer Relations strategist and technologist with over a decade of experience in bridging the gaps between a product and developers.

Over the span of his career, Ondřej Chrastina transitioned from QA and development, eventually transitioning the pain of day-to-day tasks in software development into a developer advocacy, where he aimed to solve the challenges the audience faced by providing SDKs, tutorials, starter packs, and other resources. Later on, Ondřej established and led developer relations programs at multiple companies.

He began his career as a QA engineer on Kentico’s .NET Digital Experience Platform (DXP), working on content management, online marketing, and e-commerce modules. His curiosity for developer pain points led him to co-create internal tooling and eventually transition into Kentico’s first dedicated Developer Advocate, helping digital agencies and their developers to be successful with the product. As Ondřej's career evolved, he moved on to lead Developer Relations at Kontent.ai (spin-off from Kentico), a SaaS headless content management system (CMS), supporting developers with dev tools in various technologies, primarily in TypeScript, JavaScript, and .NET. Before joining CKEditor, Ondřej led the Developer Relations team at Ataccama, where he helped data engineers with data quality by providing a Python SDK, formalized API standards for the company’s new cloud platform, and researched integration possibilities with data platforms like Snowflake, Databricks, Airflow, etc.

Beyond corporate roles, Ondřej explores open-source projects on GitHub, shares technical insights on his YouTube channel, and writes on tech blogs. A graduate of Masaryk University (M.Sc. Applied Informatics) and Brno University of Technology (B.Sc. IT), he speaks at international conferences about Developer Relations, dev tooling, and developer experience. When he’s offline, you’ll find him planning travel, exploring gastronomy, or tinkering with DIY projects or the next JavaScript framework.
