Production-grade AI systems for teams past the prototype.

We build, refactor, and scale the AI applications that move from demo to revenue. Engineering rigor where vibe-coded systems fall apart.

The full picture

What a production AI system actually requires.

Most AI demos are 20% of the system. We build and operate the other 80%.

Capabilities

Where we work across the lifecycle.

01

AI application engineering

RAG systems, agent workflows, multi-LLM orchestration designed for accuracy under load.

02

Vibe-coded rescue

Stabilize, harden, and scale AI systems that broke down moving from demo to production.

03

Scaling infrastructure

Streaming, persistence, evals, and observability built for real production traffic.

04

AI transformation advisory

Architecture review, model selection, and roadmaps that survive contact with reality.

The wedge

The gap between a demo and a system that ships.

Vibe-coded prototypes pass demo day. Then they meet production traffic, real edge cases, and audit requirements. We rebuild them into systems that survive.

Vibe-coded prototype versus production-grade AI system Side by side comparison: a vibe-coded prototype has only a hardcoded prompt feeding a single LLM call returning a string, while a production system adds versioning, retrieval, multi-model routing with fallback, schema validation, evals, and observability. BEFORE · VIBE-CODED works in the demo, breaks in production [1] Hard-coded prompt strings glued together at runtime [2] Single LLM call one model, no fallback, no retry [3] String response free-form text, hope for the best no retrieval · no schema · no evals no fallback · no observability no audit trail · no cost tracking REBUILD our work AFTER · PRODUCTION survives real traffic and audit Versioned prompt tracked, A/B tested Retrieval grounded context Multi-model router with fallback routes by complexity, retries on failure Schema validator typed JSON outputs Eval harness catch drift early Typed structured output + observability · audit log · drift detection + cost tracking · version control · access policies Vibe-coded prototype versus production-grade AI system Vertical comparison: top half shows a vibe-coded prototype with hardcoded prompt, single LLM call, string response, and missing infrastructure.

Selected work

Real systems, in production, under real load.

BEVERAGE ALCOHOL · COMMERCE INFRASTRUCTURE

From two prototypes to one regulated commerce platform

A creator-driven storefront for premium spirits and a compliance-first commerce backend for alcohol brands. Both started as vibe-coded MVPs that worked in a demo but couldn't survive 50-state alcohol regulation, real payment volume, or supplier onboarding.

We rebuilt them into one production platform: state-by-state compliant order routing, Stripe-backed payouts to licensed retailers, an AI insights layer over brand performance data, and a field-sales CRM iOS app for on-premise reps. Live in market in 2026.

WHAT WE SHIPPED
  • Compliance routing engine. State-by-state regulatory rules, age and ID gating, automatic licensed-retailer matching for every order.
  • Payments & payouts. Stripe-backed flow with split payouts to retailers and creator commissions, full audit trail.
  • Two consumer surfaces. A creator-curated storefront and embeddable checkout tools that drop into any supplier website.
  • Field-sales CRM. Native iOS app for on-premise reps: route planning, geo-tagged visit logs, purchase-order management.
  • AI insights layer. Performance, SKU, and campaign attribution unified across Klaviyo, Meta Ads, and GA4.

Approach

How we work.

Most AI consultancies sell strategy decks. We ship code. Every engagement starts with a working system in week two and ends with your team owning what we built.

WEEK 1

Architecture review & failure-mode analysis

We read your code, talk to your team, identify what's actually breaking.

WEEK 2

First production-shape prototype

Working system with eval harness. Not slides.

WEEK 3-6

Iterate against production traffic

Streaming infrastructure, observability, evals tied to business metrics.

HANDOFF

Your team owns the system

Documentation, runbooks, and pairing until they don't need us.

Have an AI system that needs to actually work?

We respond within 24 hours. First call is a technical conversation, not a sales pitch.
