Build. Lead. + Teach.
I'm Luke — a technical product, program, and portfolio manager who never quit being an engineer. I write the roadmaps, read the PRs, write the evals, and ship. Fortune 500s to startups, and everything between. Many courses, one journal, and a working philosophy: an attitude of gratitude.

The test I resented writing in March caught the bug I wrote today. Past me, all is forgiven.
