Aleksa Gordić spent 25 consecutive days in "monk mode" (9h/day, no social media) researching and writing his matmul optimization blog — about 221.5 hours total, verified via his 5-year daily life logs analyzed with AI. It was a side quest after leaving his startup, and he was never a dedicated performance engineer. After publishing, Anthropic reached out to interview him for a performance engineering role. His takeaway: "you can just do things."
