The premise

Most AI products never reach production. The idea isn't the problem — the architecture is.

Architecture

Calling an LLM is an afternoon. Building a reliable one is an architecture problem.

Prompt chains, context windows, memory layers, hallucination guardrails, token economics — these are not features you bolt on later.

Ownership

Four engineers in a room is four communication failures waiting.

Frontend, backend, AI, infra — every handoff doubles your timeline and halves your conviction. One owner is faster than four collaborators.

Six months and still no product

By the time most teams reach a soft launch, runway is gone and the market has moved. We deliver in the validation window, not after it.

Demo-grade code is debt

Code that passes a screen-share collapses under real load. We deliver systems that survive contact with users — and grow from there.

You keep everything

Source, infrastructure, documentation and a handover that leaves your team able to operate the system without us.

— 02Engagements

Four shapes of work. Every one ends in a deployed system you own.

AI SaaS Development

End-to-end SaaS, AI at the core

Full-stack platforms with LLM integration, retrieval pipelines, vector search, authentication, billing, and scalable cloud infrastructure. Database to deployed product.

2–4 weeks
Automation Systems

Workflows that retire manual work

AI pipelines that process data, generate content, and make decisions across your existing toolchain. Hours of human labor compressed to minutes of compute.

1–2 weeks
Multi-Agent Platforms

Specialized agents, orchestrated

Systems where multiple agents collaborate — each with a defined role, shared memory, and coordinated decisions. Built on Google ADK, LangChain, and bespoke orchestration.

3–6 weeks
MVP Development

A real product in two weeks

Validate with a working, deployed product — never a mockup. Authentication, core features, AI integration, cloud deployment. Shipped before the market changes its mind.

1–2 weeks
— 03Selected work

Systems running in production. Real data, real users, real numbers.

Agents in production
Multi-Agent Platform · Therapy

Therapeutic AI that remembers across sessions.

Off-the-shelf chatbots couldn't hold therapeutic nuance or recall a patient between visits. Seventeen specialized agents on Google ADK + Vertex AI, with two-tier memory (session + long-term), real-time WebSocket delivery, and clinical safety guardrails enforced at the orchestration layer. Built for Kahani.

An algorithmic engine that reads markets in real time.

Manual analysis couldn't track the speed of a modern derivatives book — signals arrived hours late. A multi-agent trading architecture with BigQuery ML forecasting, ARIMA+ models, 120+ technical indicators, and automated execution via the Binance API. End-to-end latency in the low hundreds of milliseconds.

A learning platform that adapts to every student.

Static curricula failed students at the edges — those moving too fast, too slow, or simply differently. Personalized learning paths driven by real-time progress analytics. Infrastructure scales to thousands of concurrent students without operator intervention. Built for AI Campus.

Enterprise · NLP at scale

A pipeline that reads a billion records.

Enterprise clients — including Rio Tinto and Caterpillar — needed sentiment and signal extraction across volumes their existing tools couldn't ingest. Cloud-native ETL pipelines with NLP-powered sentiment analysis. Built for throughput, observability, and graceful degradation. Hand-tuned for cost-per-record.

Automated Quoting · Live in Production

An AI quoting engine clearing two thousand transactions a day.

Manual phone-and-spreadsheet quoting couldn't scale — a national vehicle-buying operation needed instant, accurate offers, twenty-four hours a day, with no human in the loop. A live multi-step quoting platform at sell.junkcarboys.com. VIN decoding, market-data ingestion, and a tuned valuation model produce an offer in under three seconds. Routing, dispatch, and payout flow through the same pipeline. Currently clearing 2,000+ transactions per day.

Not a sales script — a system shape. Stack choices, top risks, and an honest timeline. Generated live.

ARCHITECTURE

A vector-search retrieval layer (Qdrant) feeds a prompt-chained Claude reasoning service behind a thin API. Background workers index and embed new content; the read path stays under 400ms p95.

STACK

Next.js + FastAPI + Postgres + Qdrant + Vertex AI Gemini 2.0 Flash for embeddings, Anthropic Claude Sonnet for generation. Cloud Run on GCP. Pino + Sentry.

RISKS

  1. Token costs scale with index size — need an embedding-cache and result-cache strategy from day one.
  2. Hallucination on edge cases — guardrail with retrieval-grounding + per-source citations exposed to the user.

TIMELINE

4–6 weeks for one senior engineer to first production traffic.

— 06Method

From conversation to deployed system, in four movements.

i.

Discovery & free prototype

Send your requirements. You receive a working prototype and a fixed-price architecture proposal with milestones — at no cost. If the work isn't right, you walk away with the prototype.

ii.

Architecture design

System topology, model selection, data pipeline, infrastructure. The blueprint is approved before a line of production code is written.

iii.

Build · weekly sprints

Working software at every checkpoint. No status reports, no slide decks — only demos against running infrastructure.

iv.

Deploy & transfer

Production deployment, full documentation, complete source ownership, and a knowledge transfer that leaves your team able to operate the system independently.

— 07The studio

Fifteen years of production systems — one architect.

I have been building software since before AI meant large language models — fifteen years across enterprise platforms, trading systems, large-scale data pipelines, and SaaS products.

I've held CTO and senior engineering roles at companies processing billions of records, building multi-agent AI systems, and shipping software used by thousands. Enterprise clients have included Rio Tinto, Caterpillar, and Revuze.

Today the studio focuses exclusively on AI-powered SaaS products. Every engagement benefits from patterns refined across more than fifty production deployments.

You do not pay for learning curves.
