Python • AI • Community Leader

About

I'm a backend engineer passionate about Python, AI/LLM integration, and building systems that work. I'm also a public speaker, open source contributor, and consultant helping teams navigate technical challenges.

Latinx technologist. Builder of responsible & ethical tech. Python educator. Conference speaker. Claude Chicago Ambassador. Ex-Python Software Foundation Chairperson. Abides by the motto: live long, Python & prosper.

Professional Background

I've spent 10+ years building production systems, leading technical initiatives, and contributing to the open source community. My background spans data engineering, fullstack and backend architecture, and increasingly, bringing AI capabilities into production systems thoughtfully.

Leadership & Community Roles

  • PSF Fellow and Ex-Chairperson — Python Software Foundation
  • Founder — PyLadies Chicago
  • City Ambassador — Claude Chicago

These roles reflect my commitment to building inclusive, sustainable open source communities where people can learn, grow, and contribute meaningfully.

I came to engineering through a bootcamp (Rails/SQL immersion in the early SaaS boom), which shaped my practical approach to building software. Today, I'm focused on helping others navigate the rapid changes in our industry — whether you're a bootcamp grad, traditional CS student, or career changer.

What I'm Currently Focused On

  • Backend Engineering — Python, async patterns, system design, scalability
  • Fullstack Development — Building end-to-end products with Python backends and modern frontends
  • AI/LLM Integration — Building production features with language models (RAG, embeddings, function calling)
  • Open Source — Contributing to and maintaining projects that matter
  • Technical Speaking — Sharing knowledge on backend patterns, AI integration, and ethical technology
  • Consulting — Working with teams on technical strategy and architecture

Consulting

I offer technical consulting for backend teams and organizations looking to integrate AI capabilities thoughtfully into their systems. Areas of focus:

  • Backend architecture and scaling
  • Python best practices and performance
  • AI/LLM integration strategies
  • Technical leadership and mentorship
