๐Ÿ“š Philosophy

Iโ€™m drawn to existential themes, complexity without chaos, and structured minimalism โ€” in both software and life. My favorite authors include Camus, Orwell, and Bulgakov. I build things that matter, learn what I must, and discard what I don't need. I prefer expressive, low-abstraction code and work best when I'm close to the metal โ€” from raw SQL queries to direct RPC calls. I read Camus, write Rust, and often build tools before using them.
