Java Champion • Principal Software Engineer at IBM
I'm a Java Champion and Principal Software
Engineer at IBM with over 25 years of experience building
enterprise-grade applications. I've been a professional developer
since 1997, using a variety of languages, including Java, Kotlin,
C/C++, JavaScript, PHP, Python, Delphi, C#, and even a bit of COBOL
and JCL. I currently work for IBM on the WildFly/EAP team, where,
among other things, I maintain integrations for OpenTelemetry and
MicroProfile Telemetry, Micrometer, Bean Validation, and Jakarta Faces.
As President of the Oklahoma City JUG, I'm passionate
about community building, mentoring developers, and advancing the
Java ecosystem. I am a frequent speaker at our local JUG, as well
as at a variety of technical conferences across the country.

Testing Your Multiplatform App
We’ve put a lot of effort into our app so far, and we’re almost 'done' with it, but there’s a pretty obvious (I hope) gap: testing is completely manual, and that’s fine at first. At some point, though, it would be nice to be able to stop tapping and typing every time we make a change. The good news is that time is now. In this post, we’ll create an.....
One of the less glamorous parts of maintaining a software project is release management. A release might include creating application bundles, signing artifacts, pushing to stores like Maven Central or Homebrew, creating GitHub releases, and announcing the release. The more complex a project’s release requirements are, the more opportunities for error. JReleaser helps streamline this process. In this post, we’ll take a quick look at what the tool is and see a fairly.....
Securing Claude Code: Guardrails for AI-Assisted Development by Jim Manico
In a presentation to OWASP London, Jim Manico, founder of Manicode Security, presents how he uses Claude Code to bootstrap projects safely using Claude Code and carefully scripted prompts and inputs. Using the approach he demos, developers won’t just vibe code sloppy, insecure software, but will set up their projects to get deterministic, high quality results.
Manico begins by starting Claude and having it create a new repository on GitHub. Once the repository.....
Sharp-eyed readers of this series may have noticed something…suboptimal: Up until this point, we’ve been creating certain objects as global variables. They’re immutable, so that may be technically OK, but those of a certain age have been taught for years how wrong that is, so technically OK or not, it just feels gross. In this post, we’re going to fix that with by implementing inversion of control with Koin...
In the last entry, we looked at how to read data from the device’s local database using Room and display it on the screen, but we did so using dummy data. In this entry, we’ll look at how to use Room in our components to persist user-entered data in our SQLite database...
In the last post — months ago (and, yes, I hand typed the em dash, not some soulless AI :) — we added support for the Room database API, so now we can store data, but we have no way of seeing what we’ve saved. We also have no way of giving it data to save. In this post, we’ll tackle the first part by creating views to show what we have, then loading the database.....
In addtion to the above, I have published Java 9 Programming
Blueprints, and actively contribute to several major open-source
projects, including WildFly, Undertow, and Arquillian.
I am a life-long learner who loves to apply what I've learned to
real-world business problems to find a solution to make employers and
customers alike happy. My favorite place to be is slightly out of my
depth as I strive to grow while bringing value to the project.
On the personal side, I'm active in my church and enjoy bass guitar, running, fishing, and a variety
of martial arts. I'm also married to a beautiful woman and have two boys, who, thankfully, look like
their mother.
