I own infrastructure, CI/CD, and backend architecture in production at NSquared: Google Cloud, Docker, GitHub Actions, PHP and Laravel on MySQL and Redis, Apache Superset and BigQuery, and Cloudflare.
The first code I wrote generated geometry under constraint. The code I write now proves work before it ships. Four turns between the two.
I started in 3D and design in 2014. By 2016 the real work was code: Rhino, Grasshopper and Python generating geometry under constraint, judged by what it did rather than how it looked. An idea stopped being an opinion to defend and became something you evaluate on performance metrics.
I was building either way. In 3D, most of the distance between an idea and the finished thing was friction that had nothing to do with the idea. Digital cut that distance: what I can describe, I can build, run and change the same day. I moved to where building carries the least friction.
I joined NSquared in 2022 on one read of its founder: someone who told the truth about things, including the inconvenient parts. I spent the first months learning the systems end to end, which is the fastest way to find out what in them actually matters. From then on I measured a contribution by whose attention it freed, not by how interesting it was.
I lead DevOps and automation for the team: infrastructure, pipelines, backend architecture, and the AI-assisted workflows around them. The way work gets proven before it ships used to be one person's habit. It is now the team's.
Built with the team at NSquared , except the last, which is my own. Each card names the product, the stack, and the part I carry.
The accessibility testing tool built for busy digital teams, and for the people those teams are building for.
Dashboards and reporting that partners provision for their own clients, on live data.
The open-source BI platform under the dashboards.
A piece of the 3D years I kept: personalized e-commerce in realtime 3D, in the browser.
Engineers wait less for builds and tests, releases spend less time in manual testing, and nobody logs into servers one at a time any more. Every number here was measured on a real system, and each card says what it counts.
How long an engineer waited to hear whether a push passed, on GitHub Actions.
The time a release spent in manual QA before browser tests ran in the pipeline.
One bar per year since 2019.
Three subjects the work keeps coming back to.
How long the team's tests took to run in CI. Same tests, same assertions, both times.
Every time someone opened a shell on a server themselves, before one command did it for them.
Everything I logged between 8 July and 2 September 2026, sorted by what it was for.
Written from inside the work, after the fact: what was decided, what it cost, and what held up in production.
Getting speed from AI without handing it the decisions: how the tools fit into real work, and where they quietly replace your judgment if you let them.
