GuillaumeBrousse

Freelance AI engineer & full-stack developer

I spent seven years building software for companies in Auckland, about as far from France as you can get without leaving the planet. Now I'm back in France, in Angoulême, working for myself. So instead of a timeline, here's a tunnel.

Angoulême

Sediment, 0–12 km

Hardware first, then the web

Bordeaux and Charente. A soldering iron, a drone, and the first Symfony apps.

    Parking Facile

    Symfony developer, Bordeaux, France

    A parking platform built from scratch: Symfony APIs, admin and customer apps, an Ionic mobile app, and Stripe, Twilio, Mailjet and Slack integrations. Page loads dropped by 60%.

  3. 2017–2023

2019: moving to the other side of the planet

Angoulême to Auckland is roughly 19,000 km by plane. Through the middle it's 12,742.

  1. 2019–2021

    Serato

    DJ software used worldwide. Ran the API services behind it (Braintree, Zendesk, ActiveCampaign, Slack), the AWS infrastructure, and moved a legacy Magento store onto a REST API.

Onit, step one: senior engineer

  1. 2023–Sep 2024

    Onit

    Senior software engineer, Auckland, New Zealand

    Joined as a contractor and stayed. Brought TypeScript into the codebase, built serverless APIs on AWS, set up CI/CD and test automation, and shipped the first AI integrations.

The hottest layer is AI

Three roles at Onit, each one closer to where AI meets real customers.

    Onit

    Forward deployed engineer, Auckland, New Zealand (remote from Bordeaux)

    Out of the lab and into the field: working directly with Onit's customers to get its AI into their real workflows, from integration and deployment to turning what they need into product.

6,371 km. The centre of the Earth.

From here on, down is up.

Ascent, 7,592 km

Back on my own

After Onit, I went independent. Same tunnel, new machine: I'm the one steering it now.

Oct 2026–now

Freelance

Freelancer, solopreneur, Angoulême, France

Back on my own, with everything the tunnel taught me. I help teams put AI into production and build the platforms around it: client portals, document generation, integrations, and websites that load fast.

Auckland

You made it through. I've since made the trip back: I'm freelancing from Angoulême now, for clients anywhere. Need AI in production, a platform or a website? The machine's console is still on: type contact, or help to see what else it does.

Strictly speaking, Angoulême's antipode is in the Pacific, about 1,080 km from Auckland. We corrected course somewhere in the mantle.
