Senior Rails Developer – AI-First Development (Claude Code / Cursor Required)
Zubair knocked it out of the park on a ServiceTitan integration project for us. He came in, got up to speed on our Rails codebase fast and wrote clean backend code that matched our existing patterns without hand-holding. Highly recommended.
