Production AI architecture and implementation

Most of the work is getting language models and machine learning into existing software: retrieval, agents, evaluation, and the data pipelines underneath. I design the system and write the first production version.

  • 01RAG and knowledge systems with cited answers
  • 02LLM agents for extraction, search, and internal tooling
  • 03Evaluation, monitoring, and cost control
  • 04Classical ML when a language model is the wrong tool

Where this work usually starts

Teams rarely struggle with choosing a model. They struggle with data access, permissions, evaluation, latency, and who owns the system after launch. That is the work I take on.

A prototype that never shipped

The demo looks fine in a meeting. There is no measure of quality, latency, or cost under real use, so it stays a prototype.

EvaluationHardening

Internal knowledge that is hard to search

Documents, tickets, and wikis sit in several tools. People want answers with sources, and security needs permissions respected.

RAGGraph retrieval

Manual document and metadata work

Incoming files or records that someone reads, classifies, and re-enters. Extract, validate, and write back, with a person in the loop when confidence is low.

ExtractionAgents

Inference that is too slow or too expensive

Every request hits the largest model. Routing, caching, and smaller models usually cut cost without changing what the user sees.

CostLatency

A prediction problem, not a language problem

Scoring, forecasting, ranking, or image classification. A trained model on your data is often cheaper and more reliable than an LLM.

MLComputer vision

Architecture that is expensive to reverse

Build versus buy, model choice, retrieval layout, cloud vendor. A second opinion before you commit budget.

AdvisoryReview

How engagements are structured

Scope and fee are agreed in writing before work starts. Most clients begin with the audit. If we continue within 30 days, that fee is credited against the next engagement.

Fractional AI Architect

€4,500/mo
1 day a week · monthly

Ongoing architecture once a system is live. A second day a week is €4,500 more per month.

  • Design and pull-request review
  • Model upgrades and vendor choices
  • Monthly quality and cost notes
  • Priority support
Details

Ranges depend on scope. After a short call you get one fixed price in writing. Model and hosting usage is billed at cost. Fees include VAT.

A typical engagement

We pick one workflow, agree how success is measured, and stop if the evidence does not support going further. If a language model is not the right answer, I will say so on the first call.

  1. 01

    Introductory call

    The problem, the current systems, and whether this is a useful fit.

    30 min · no charge
  2. 02

    Audit

    Data, infrastructure, and process reviewed. Written recommendation.

    5 days · fixed fee
  3. 03

    Architecture

    A design, an evaluation plan, and a costed backlog your team can build from.

    2–4 weeks
  4. 04

    Production

    One workflow on your data, measured against a baseline, then monitored and handed over.

    4–8 weeks

How the work is done

You work with me throughout

From the first call through to production, you talk to me. I design the system and write the code. Nothing is passed on to someone else after we start.

Built to last

I build AI pipelines that stay useful after launch: monitored, straightforward to change, and not tied to a single model version as the stack moves on.

Measured before it ships

Quality, latency, and cost targets are agreed up front. If a change cannot be measured, it does not go out.

Your repository, your cloud

Code, runbooks, and dashboards stay with your team. You should not need me to keep the system running.

If you have a system in mind, we can talk through it

Thirty minutes is usually enough to decide on an audit, a build, or that this is not the right next step.
