Builds
Full-stack platforms, built from scratch.
Data ingestion pipelines, feasibility and scoring engines, AI review tools, payments and portals. Built on Next.js, TypeScript, Node.js, Postgres, Supabase and Stripe.
Screens shown are mock-ups. Our clients' platforms are under NDA.
AI isn't a critical thinking tool.
It will automate anything you point it at. If nothing checks what goes in, keeps it secure and checks what comes out, the results don't mean much. That part takes someone who designs the system.
Data coming in, checked firstExample
- New lead from InstagramFormatSecurityRulesPassed
- Invoice #2041, $1,250FormatSecurityRulesPassed
- Order with no emailFormatSecurityRulesStopped: missing email
- Lot 14, zoned R2FormatSecurityRulesPassed
- Form with code pasted inFormatSecurityRulesStopped: unsafe input
- Price outside your rulesFormatSecurityRulesStopped: needs a person
Check what comes in
Data is checked before AI touches it. Bad records get stopped, not guessed at.
Lock it down
Keys, customer data and who can see what, set up properly from day one.
Rules, not guesses
Prompts carry the rules of your business, so the same input gets the same answer.
Check what comes out
Results are tested before anyone relies on them.
It's how we build our property feasibility platform and our data ingestion pipelines. See the feasibility build or the customs data pipeline.
