Cesar Alejandro Mostacero Palomo

I’m a Senior Data & AI Engineer with 6+ years mentoring on Codementor, helping engineers grow from junior contributors to confident senior builders. I specialize in real-world, production-grade systems — not tutorials — and I work hands-on with modern data stacks, distributed systems, and Generative AI.

I’ve mentored engineers from companies like Microsoft and Apple. My focus is practical: debugging complex Airflow pipelines, designing scalable data platforms, building AI-powered features, or navigating career growth in data engineering.

I work at the cutting edge of AI and data — including LLM systems, vector databases, semantic pipelines, observability (Prometheus/Grafana/Datadog), cloud-native infrastructure, and scalable data architecture. I’m also an early adopter AI-certified practitioner and hold multiple cloud and data certifications, bringing both hands-on experience and validated expertise.

If you’re looking for a mentor who can explain things clearly, challenge your thinking, and help you build systems that actually run in production — I’m here to help.

Let’s build something solid.
