About
My name is Jean-Louis Monteiro. I have been writing software for over twenty years, and I live in Touraine, in central France.
An engineer, not an agency
Software engineering is my main profession. I lead the engineering team at Tomitribe, an American company based in Santa Monica, California, which builds and maintains Java application servers used by large enterprises worldwide. English is my working language, day in and day out.
The job is not only code: project management, software and technical architecture, and a good deal of expertise — people call me in from all over the world to untangle problems of architecture, performance or security.
With Kaluna Technology, I bring those standards to businesses in my own region: digital tools that are simple, dependable, and that you stay in control of.
Security, every day
A good part of my work at Tomitribe is tracking the published vulnerabilities — the “CVEs” — that affect the servers we maintain, writing the fixes, and getting them to the companies that depend on them as fast as the flaw warrants, including for versions their original vendor no longer supports.
How fast depends on what we are facing: a zero-day, already being exploited before any patch exists, gets dropped on everything else; a less critical vulnerability follows the normal release cycle. The severity sets the deadline, not the other way round.
This is not new ground: at Worldline I had already built the group’s security framework, compliant with the PCI standard that governs the handling of payment card data.
It is a job of vigilance and patience: read the code, understand the flaw, fix it without breaking anything else.
I bring that same reflex to what I set up for you. A site with no database has almost nothing to attack. A WordPress site does. Either way, it is the updates, the backups and the monitoring that make the difference — and that is exactly what I take care of.
Open source, all along
- Member of the Apache Software Foundation since 2008 — membership there is by invitation
- Project Management Committee Chair of Apache Geronimo and Apache Johnzon
- PMC member on Apache TomEE, Apache OpenWebBeans, Apache BatchEE and the Apache Incubator
- Committer and committee member at the Eclipse Foundation since 2018, where I took part in the move from Java EE to Jakarta EE
- Member of the Java Community Process expert groups: EJB 3.2 and Java EE Security
- Named a JavaOne Rock Star in 2015
I believe open source software is the best guarantee of your independence: no captive subscription, no closed format, no dependency on an American giant.
I speak about this work in public
I speak regularly at conferences — JavaOne, Devoxx, ApacheCon, QCon — and at Java user groups, in France and abroad: from the United Kingdom to Brazil, by way of the United States, Portugal and Lithuania. I also taught Java EE for four and a half years at Polytech’Tours, at master’s level.
Explaining a technical subject to a room that does not share my background is good practice. It is exactly what I do when I explain to you what I am proposing, and why.
Four languages
I speak French, Portuguese and English fluently, and I get by in Spanish. That comes in handy more often than you would think: taking over a site aimed at several countries, dealing with a foreign supplier’s support desk, or simply sparing you the job of translating.
Why “Get it right”
Because a site, an email address or a campaign done properly the first time costs less than three attempts at fixing it. It has been Kaluna Technology’s motto since the company was founded in 2014.
