Johnny Santiago Valdez Calderon’s Tips for Aspiring AI Engineers
Here are some of the key insights he shares with aspiring AI engineers.
1. Learn the Fundamentals First
One of Johnny’s earliest points is simple: don’t rush past the basics. Before diving into deep learning libraries or transformer models, he advises building a strong foundation in math and programming.
“You need to understand linear algebra, probability, statistics, and calculus. Not just for exams, but to build real systems that work,” he explains.
Python is the go-to language for AI, but Johnny also encourages new engineers to understand how things work under the hood. Grasping the inner workings of gradient descent or a loss function helps you troubleshoot and improve your models in meaningful ways.
2. Get Comfortable with Data
AI doesn’t live in code alone—it breathes through data. Johnny emphasizes that working with messy, inconsistent, or biased data is part of the job.
“Real-world data is never perfect,” he says. “Learning how to clean it, balance it, and draw insights from it is a critical skill.”
Whether it’s scraping data, building pipelines, or simply understanding what makes a dataset valuable, aspiring engineers must treat data handling as a core responsibility, not an afterthought.
3. Build Projects That Solve Real Problems
Johnny is a big advocate for learning through doing. He often tells beginners to stop trying to master every algorithm and start solving specific problems.
“You learn more from building one solid end-to-end project than reading ten papers,” he explains.
He recommends working on problems that intersect with your personal interests—whether it’s healthcare, climate, education, or finance. This not only sharpens your technical skills but also shows potential employers that you can apply AI meaningfully.
4. Stay Curious, But Don’t Chase Every Trend
In an industry moving as fast as AI, it’s tempting to constantly chase the latest model or tool. Johnny urges young engineers to stay grounded.
“It’s okay to explore new models, but depth matters more than novelty. Understand one framework deeply rather than skimming through five,” he advises.
He points out that trends come and go, but the engineers who truly excel are those who can solve problems reliably and think critically about their tools.
5. Collaborate and Communicate
AI engineering isn’t a solo journey. Johnny believes one of the most overlooked skills in tech is communication.
“You’re not just building for machines—you’re building for people. You need to explain your models to non-technical stakeholders, collaborate with teams, and listen carefully.”
He encourages engineers to write about their projects, join discussions, and be open to feedback. Collaboration, he says, leads to better ideas and fewer blind spots.
6. Understand the Impact of Your Work
Finally, Johnny speaks often about the responsibility that comes with working in AI. As systems become more influential in daily life, ethical considerations are essential.
“It’s not enough to build something that works. You need to ask: Is it fair? Is it explainable? Who might it harm?”
He believes engineers should be as invested in fairness and transparency as they are in performance metrics.
Conclusion
Johnny Santiago Valdez Calderon’s advice doesn’t come from a textbook—it comes from years of practice, reflection, and real impact. For anyone entering the AI space, his insights serve as a grounded roadmap: focus on fundamentals, stay curious, build meaningfully, and never lose sight of the human side of technology.
