The Product BasinCheck (https://basincheck.com) replaces the clipboard/Excel workflow for Safety Managers in the Permian Basin. It handles offline audits, hot work permits, and automates OSHA 300 logs.
The Stack
Next.js (App Router): Monorepo setup lets me spin out features as standalone free tools for SEO/lead gen.
Supabase: The path of least resistance for backend/auth.
Resend: For all transactional/marketing emails.
Stripe: Stuck with the standard despite the Polar/Lemon Squeezy hype. The SDK coverage made it easier for LLMs to generate reliable integration code.
AI: Used for parsing incident descriptions to suggest OSHA codes. Hard rule: AI is read-only/suggestion mode. A human (Safety/HSE manager) must approve every classification.
The "Vibe Coding" Reality Check
The biggest lesson so far: AI leaves logic gaps. I asked the AI to "alert me on new signups," which it did—for email/password forms. I missed my first real user for 5 days because the AI didn't intuitively know to hook those same alerts into the Google OAuth callback.
Fix: Moved logic from client-side to Postgres triggers on auth.users to catch everything at the DB level.
Happy to answer questions on the prompting workflow or the "boring" industrial tech stack.
