Hi, I'm Pablo De La Cruz 馃憢

AI Engineer 路 Technical Trainer at Revature 路 Developer Educator

I help developers and teams turn AI capabilities into systems they can understand, evaluate, and adopt. I build production-shaped prototypes across LLM applications, RAG, agentic workflows, data, and cloud鈥攁nd turn the hard parts into clear demos, practical labs, and reusable engineering patterns.

I've mentored 500+ engineers, with a focus on making emerging technology approachable without hiding its tradeoffs, failure modes, or production boundaries.

Selected work

Project What it demonstrates
AI Engineering Notebook A validated builder's notebook for LLM applications, RAG, agents, evals, integrations, and AI product design
FFXI AI Agents Lab A local-first agent lab with bounded MCP control, fail-closed safety, observable actions, and live YouTube gameplay streams
Support Triage Review Console A customer-facing AI workflow with bounded model calls, exact-schema validation, human review, safe failure handling, and layered cost controls
Agentic Workflow Demo Typed tool contracts, approval-gated actions, refusal behavior, structured traces, and behavioral evals
Prompt Regression & Feedback Pipeline Fixed-case prompt comparison plus an explicit path from human corrections to reviewed candidate evals
Enablement Assistant RAG Grounded answers with source-aware retrieval, citations, refusal behavior, and an 18-case evaluation suite
Mocked Support Adapter Signed webhooks, replay protection, PII redaction, strict mapping, and proposed-only customer-system updates
StreamFlow Analytics Platform Streaming and analytics architecture across Spark, Airflow, Snowflake-style modeling, BI semantics, and reconciliation checks
Data Analytics Learning Lab Synthetic, source-backed product analytics practice with decision-ready reports and reproducible evidence
HTML-in-Canvas Lab Emerging browser capability explored through original demos, progressive enhancement, and accessible fallbacks
Portfolio A focused view of my projects, working principles, technical range, and public contact points

How I work

  • Start with the real workflow: connect technical choices to a user, operating constraint, and measurable outcome.
  • Make trust inspectable: expose sources, schemas, traces, evals, approval boundaries, and failure behavior.
  • Teach the whole system: turn architecture and debugging decisions into demos, labs, tests, rubrics, and reference implementations.
  • Name the production boundary: distinguish a compelling prototype from what identity, privacy, observability, reliability, and scale still require.

Current focus

  • AI developer enablement, solution architecture, and technical storytelling
  • Eval-driven LLM applications, RAG, and tool-using agents
  • Human-in-the-loop workflows, safety boundaries, and observability
  • Data engineering, analytics, and distributed systems
  • Developer tooling, technical curriculum, and accessible web experiences
