## In their own words

Most of my work has been on systems older than the team maintaining them. I am good at untangling something that grew rather than was designed, without proposing a rewrite nobody asked for.

## Where they have worked

Employers are described rather than named. The candidate decides when that changes.

- **Java Engineer**, manufacturing software, 2024 to present. Current role.
- **Java Engineer**, energy, 2022 to 2024. Built the part of it that is still running.
- **Java Engineer**, agritech, 2020 to 2022. Good team, product that never found its market.

## What they are looking for

- Legacy I am allowed to actually improve
- A domain with real constraints
- Reviews that happen before the code

## What is not on this page

No email, no phone, no messenger handle, no links, no photograph and no employer names. None of that is withheld as a paid upgrade: it stays with the candidate until they accept an introduction, and no amount of money moves it sooner.

## How to reach them

You do not message this person directly and there is no contact to unlock. You describe your role to the AI assistant you already use, and it asks whether they want to talk. They decide, and only then do contact details reach you.
