AI Consultant · Solution Architect · Lead Engineer

I help companies put AI to work — the kind that actually ships, not the kind that lives in a slide deck.

I've spent twelve years building software across SaaS, fintech and AI — leading teams, owning the architecture, and shipping GenAI that people really use. These days I mostly help companies figure out where AI fits, then build it with them.

What I do

A software engineer whose focus is AI consulting — I help you decide what to build, then I build it.

For over ten years I've shipped real software — React, Node.js, Rust, cloud. Now I point that experience at AI: working out where it genuinely helps your business, planning how to get there, and then building it with you. You get the advice and the engineering from the same person, so the plan doesn't get lost somewhere between the strategy deck and production.

Consulting, from frontier tools to custom AI

How I take a business from “we should use AI” to a running system — model selection and agentic build, RAG on your data, custom models, and end-to-end delivery.

01Frontier AI

Build with the best models — Claude, GPT, Gemini, Perplexity, Grok

I pick the right model for each job and let coding agents like Claude Code and Codex do the heavy lifting, so you get the best result without getting tied to one vendor.

  • Model routing by task, with evals & fallbacks
  • Agentic development with Claude Code & Codex
  • Live web research with Perplexity & Grok
  • No vendor lock-in by design

02Your data

Ground AI in your data with RAG

AI that answers from your own content and shows where each answer came from — so you can trust it, instead of hoping it didn’t make things up.

  1. 1Chunk & embed your content into a vector database
  2. 2Retrieve, rerank & filter the right context per query
  3. 3Ground the answer with citations, then evaluate

03When an API isn’t enough

Custom & self-hosted AI models

Open models on your own infrastructure, tuned to your data — for when privacy, cost or a very specific job mean a public API just won’t cut it.
