The best way to reach me is LinkedIn. You can also email val@vkafed.com.

Professional connections

For technical discussions, peer connections, or questions about my background, LinkedIn is a good starting point.

Include the topic and any public article or repository that gives the conversation context.

Speaking and press

Include the event or publication, the topic, the audience, the format, and the date or deadline.

The speaker bio and portrait are available for event introductions and listings.

Technical conversations

I am happy to talk about infrastructure architecture, networking at scale, platform security, and AI infrastructure. For a question about an article, include its link and the part you want to discuss.

Code and reference implementations are on GitHub. If a question concerns a public repository, its issue tracker keeps the discussion close to the code.

Please leave credentials, private keys, customer data, and confidential architecture out of an initial message. Keep technical questions grounded in public examples or sanitized descriptions.

How messages and website data are handled is described in the privacy notice.
