A software engineer interested in systems, agents, and protocols.

I work across the stack, from operating systems and virtualization to distributed services, AI agents, and smart contracts.

I am particularly interested in multi-agent coordination, memory and context management, event-driven systems, cryptography, and the boundary between software and physical devices.

I mostly write Rust, Java, Python, TypeScript, and C. I do not regard languages and frameworks as identities; they are agreements between programmers and machines. What matters is understanding the abstraction, and knowing when to look below it.

I value simple interfaces, explicit state, observable failures, and software that respects its users.

I am always glad to talk about systems programming, distributed systems, agent infrastructure, cryptography, or smart contracts.

Here are a few tips you might find useful.

Simply add Markdown files (or folders) to the blog directory.

Regular blog authors can be added to authors.yml.

The blog post date can be extracted from filenames, such as:

  • 2019-05-30-welcome.md
  • 2019-05-30-welcome/index.md

A blog post folder can be convenient to co-locate blog post images:

The blog supports tags as well!

And if you don't want a blog: just delete this directory, and use blog: false in your Docusaurus config.

tip

Use the power of React to create interactive blog posts.

For example, use JSX to create an interactive button:

<button onClick={() => alert('button clicked!')}>Click me!</button>
