About Me

Nuclear plant operator, turned Freelancer, turned Developer Advocate.

Handsontable

As Head of Developer Experience, I am focused on making the Handsontable data grid library and HyperFormula calculation engine easier to use for both developers and AI coding agents.

Coding is evolving rapidly, and developer workflows are changing with it. I am excited to help shape this transformation, work closely with our community, and make our tools more powerful, intuitive, and AI-ready.

Appsmith

I found Appsmith because I kept hitting limitations in other platforms. They found me because I kept pushing the limits of their platform.

In 2022, I accepted a full-time position as a Senior Developer Advocate with Appsmith, and it has truly been an amazing journey.

Learning and teaching are my true passions, and Appsmith has enabled me to focus more on content creation and engaging with the community.

I am no longer available for development work, but if you are looking for training or help troubleshooting a specific issue, feel free to reach out!
