Understudy Production AI web apps & autonomous agents.
Full-stack builds, shipped and deployed — with the unglamorous parts done right: typed APIs, row-level security, signed webhooks, server-side keys, and agents that are evaluated and gated, not vibes.
How the agents are actually built
The hard part of AI isn't generating text — it's doing real work safely. In practice, that's:
Tool-use loop
Claude tool use over your real functions/APIs — observe → plan → call tools → continue. Read-and-propose by default; it never publishes or spends on its own.
Critic + human-in-the-loop
A second agent vets each action against your rules; everything lands in an approval queue. Nothing ships without your cue.
Eval harness
Outputs scored against a written contract, CI-gateable — so a prompt or model change can't silently regress. Verified, not hoped.
Safety rails
Kill switch, budget caps, dry-run, full audit log, runaway-step bounds. The boring guarantees that make it safe to run.
Secure full-stack
Supabase RLS, server-side keys, rate-limited serverless routes, Stripe Checkout + signed idempotent webhooks. Auth + entitlements wired correctly.
RAG done right
Chunk-level retrieval with citation verification — grounded answers from your real source, not hallucinated ones.
