April 14, 2026 — RGV Devs' First Official Meetup, McAllen Public Library
April 14 marked RGVDevs' very first official session, moving out of the "teaser" phase from the previous Cyber RGV talks and into a dedicated meetup built around one real, complete project. The session was a full code walkthrough of a custom-built AI brand content engine, the same one previewed the month before, broken down piece by piece from the ground up.
Starting with an ASP.NET Core Minimal API Program.cs file, the walkthrough covered how the whole system gets wired together: loading configuration to switch between AI providers, registering the Microsoft Agent Framework chat client, and building a custom brand context provider that injects an entire brand identity (tone, voice, audience, etc.) into every AI call from a single markdown file. Swap the file, swap the brand, and the exact same application goes from generating cybersecurity marketing copy to coffee shop content without touching a line of logic!
From there, things went well past "here's a demo" into genuinely production-focused territory: adding auto-generated API documentation with Scalar, locking endpoints down with a custom API key handler, layering in rate limiting to protect against abuse (and runaway AI bills!), grouping endpoints to share policies instead of repeating configuration, and even building custom middleware to time and log AI response performance. Every one of these went in as a handful of lines of code, registered into the same simple three-step pattern: register the service, wire up the middleware, tell the endpoint to use it.
One key differentiator for this event from our previous ones: his session wasn't recorded on video, and the source code as it stands after the live changes made that night are not published publicly. The resources from our live sessions (including videos, slides, source code, etc.) are being kept as a benefit for RGVDevs group members. If you weren't in the room, you genuinely missed getting hands-on with a project that's a great reference for building real, production-ready AI features on .NET.
That's not us trying to gatekeep; it's exactly the opposite! It's the first concrete example of what joining our group actually gets you: real source code, real recordings, and real access to what we're building next. Future sessions will be recorded and shared regularly, and the group is where the good stuff lives, so join us now to get access to everything we have coming down the pipeline!
This was RGVDevs' first official event, made possible once again by RGV Cyber, who continue to host us in their space and have supported this community from day one. Check out their work at rgv-cyber.org. Full event details are also up on the official event page.
