About
Engineer by training. Builder by practice.
I’m Rodolfo Baez — a Computer Engineer based in Texas and the founder of RBJ Engineering Services, LLC. I design and deliver custom software, PLC automation, and system integrations for teams that need engineering done right the first time.
Background
I hold a Bachelor of Science in Computer Engineering. My work sits at the intersection of software and hardware — where application code, APIs, and control systems have to talk to each other reliably and at scale. That mix of firmware intuition and modern software practice is the core of how I build.
Through RBJ Engineering Services, I help clients move from idea to production — shipping custom applications, wiring up integrations, and automating the kind of real-world processes that don’t fit in an off-the-shelf tool.
What I specialize in
Custom Software
Web, desktop, and backend applications engineered for reliability, observability, and long-term maintainability.
APIs & Integration
REST and event-driven APIs, third-party integrations, and data pipelines that connect systems cleanly.
Automation & PLC
Industrial control, PLC programming, and shop-floor automation that bridges control systems with modern software.
How I work
I write clean, testable code. I treat CI/CD, observability, and documentation as first-class deliverables. Every engagement starts with a clear scope and ends with something you can confidently run in production.
- Automation-first mindset — if it can be repeated, it can be scripted.
- Test coverage and verification are part of the definition of done.
- Clear communication: status, trade-offs, and risks on the record.
- Infrastructure as code and reproducible environments when it matters.
Let’s build something solid
