What people say
“The rare engineer who asks about the customer before he asks about the schema.”
“He rewrote our checkout in three weeks and it hasn't paged anyone since.”
“Clear writing, clear code, no drama. I would hire him again tomorrow.”
“He shipped the migration on a Friday and nothing broke. That had never happened here before.”
“He turned a two-year backlog into a roadmap the team could actually read.”
“The only contractor who left our codebase simpler than he found it.”
“He asks the question everyone was avoiding, then answers it in code the same week.”
