Meetme
Hi, I'm Sif
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.
