PhD candidate in Engineering (Computer Science) · University lecturer (13+ years) · Software & cloud engineer AWS Certified Cloud Practitioner · AWS Certified AI Practitioner

I teach, research, and build. I like turning hard problems into small, clean, well-explained solutions — and then teaching how they work.

• 🎓 I lecture on functional and imperative programming, algorithms, discrete mathematics, programming-language theory, and cloud computing at Javeriana Cali, ICESI and Universidad del Valle.
• 🔬 My research is on mutation testing for the security of cloud REST APIs, and on multifractality and robustness in complex networks.
• ☁️ I build modern data platforms and services in Python and Java on AWS — Iceberg, Trino, Spark and Airflow, with IAM and containers.
• 📺 I record my classes: hundreds of lectures organized by course on YouTube.
