Different Day
Human-gated AI engineering

Working solutions in days. Production-grade by design.

AI-native from first call to production. Parallel AI agents do the heavy lifting, a written spec keeps them honest, and automated checks decide what ships. Every engagement compounds: the skills library, harness, and agent team are reused, so each new client starts further along than the last.

How we build

Prototype fast. Harden for production.

Eight steps, bracketed by two commercial gates. Steps 1 to 4 put a working preview in the client’s hands in days. Steps 5 to 8 turn the approved picture into a governed, monitored production system.

Gate 1
Diagnostic

About 15 days, $10K to $15K, credited forward. NDA and DPA before any data moves. Nothing gets built without a number the sponsor agrees to.

Phase 1 · Prototypedays, not weeks
Gate 2 · Define: signed FRD + handoff pack
Phase 2 · Hardengoverned, observable, reversible
Gate 2
Define

A 9-section FRD with numbered acceptance criteria. No production build without a signed FRD and a handoff pack. Scope changes are numbered change requests.

Five patterns in production

Select a pattern

Hard calls go to a council, not a single opinion

QuestionArrives with grounded data attached.
ReasonerOne model drafts the first conclusion.
ChallengeA different model attacks that conclusion.
EvaluatorScores draft and challenge against criteria.
GrounderChecks every claim against the data.
AnswerSchema-validated output, or a flagged gap.
Routed through one gateway: OpenRouterClaudeGeminiGPTQwen IDs pinned per client, notice before any change.
Run and self-heal

Systems that recover on their own, and know when not to.

Every agent workflow runs as a durable Inngest function. When something breaks, the platform retries, resumes, or fails over inside strict limits. Anything that needs a code change becomes a pull request a human approves.

Tier 0

Durable execution

Inngest functions with step-level retries and backoff. Completed steps are memoized, so a retry resumes at the failed step without repeating side effects. Per-client concurrency keys, scheduled refreshes, and one-click replay of failed runs.

Rolling out
Tier 1

Ops agent

Listens to Inngest failure events and error tracking, classifies the incident, and takes allowlisted actions only: retry, re-run, restart, or fail over to the fallback model.

Roadmap
Tier 2

Fix agent

When the cause is code, an agent reproduces it as a failing test and opens a pull request. The workflow pauses until a human approves. It never merges its own fix.

Roadmap
Tier 3

Learn

Each resolved incident updates the runbook and the skills library, so the next occurrence is handled one tier lower, faster, and without a human.

Pick an incident and press run.

Shadow mode first: the agent proposes and logs what it would do, and humans compare it with what they actually did. Each action class is promoted to active only after it earns a clean track record.

Guardrails

  • Action allowlist: retry, re-run, restart, fail over. Nothing else runs without a human.
  • Hard budgets per incident. When the budget runs out, the agent escalates instead of looping.
  • Code changes are always pull requests, merged by a named human. Production still releases from main only.
  • Low confidence means hand over, not guess: the agent ships a diagnosis pack to the on-call engineer.
  • Every action lands in an audit trail written by the system, with a kill switch per client.

What it looks like in code

simplified
// A durable sync: retries resume at the failed step
export const syncCatalog = inngest.createFunction(
  { id: "sync-catalog", retries: 4,
    concurrency: { limit: 1, key: "event.data.clientId" },
    onFailure: ({ event, error }) =>
      inngest.send({ name: "ops/incident.opened",
        data: { source: "sync-catalog", error: error.message } }) },
  { event: "catalog/sync.requested" },
  async ({ event, step }) => {
    const rows = await step.run("pull", () => adapters.catalog.pull());
    await step.run("upsert", () => db.upsert(rows));
  });

// Fix agent: open a PR, then pause for a human
const merged = await step.waitForEvent("human-review", {
  event: "github/pr.merged", match: "data.incidentId",
  timeout: "72h" });
Security

Secure by architecture, not by promise.

Defense in depth, designed for AI systems: the model never holds the keys, never sees another client’s data, and never ships its own code. Pick a threat to see which layers stop it.

Stack and scale

Each client starts further along than the last.

A snapshot, not a ceiling. We evaluate new models, agents, and tools continuously and adopt what proves itself against our evals. Click a layer for the reasoning.

Why it compounds

Built for this clientReused as isNew per client
Scale

More clients, more load, same team.

Scale shows up in three ways, and each has its own mechanism. The one deliberate limit is human review, and we keep that fast with small pull requests and automated checks.

More clients

Configure, don’t rebuild

The skills library, harness adapters, and templates mean a new client is configuration and data wiring. Code becomes shared the moment a second client needs it.

Live
More load

Elastic by default

Stateless containers on Cloud Run scale out on demand. Postgres on Neon scales compute and branches per environment. The model gateway fails over across providers.

Live
More work

Compute, not headcount

Parallel agents scale throughput with compute. Specs, tasks, and checks let new engineers and agents onboard from the written goal, not tribal knowledge.

Live

Trust and proof

We don’t claim what we haven’t shipped.

Controls that exist today, what is next, and where the system already runs in production.

Security and control

  • NDA and DPA signed before any data moves.
  • Separate databases per client and per environment.
  • Secrets in a vault. A named human merges every change.
  • Nothing trains on client data. Local embeddings keep retrieval data in our containers.
  • You own the repo and the data: standard TypeScript on Postgres.
