Hey, I'm Julissa, an AI Engineer at Polly with 8+ years of full-stack development experience. I specialize in building production-ready AI systems, from retrieval-augmented generation (RAG) pipelines to agentic workflows that transform how businesses operate.

My journey as a self-taught developer began unexpectedly when I stumbled into a hackathon and never looked back. Now, with nearly a decade of experience under my belt, I'm passionate about creating innovative AI-powered solutions and sharing my insights with the tech community.

I create content about AI engineering, scalable architectures, and practical solutions to complex technical challenges. Through my writing and public building, I share insights from both production AI systems and experimental personal projects.

What kind of stuff do you find here?

In-depth technical articles covering:

• AI Engineering: RAG systems, agent architectures, and production AI implementation strategies
• System Architecture: Async patterns, microservices design, and scalable infrastructure decisions
• Automation & Workflow: n8n orchestration, FastAPI services, and intelligent process automation
• Frontend Challenges: iOS browser limitations, voice interface optimization, and cross-platform solutions
• Privacy & Security: Data-sovereign AI, self-hosted solutions, and privacy-first design patterns

I share real-world experiences, architectural decisions, and practical solutions from building production AI systems. Whether you're implementing your first RAG pipeline or scaling an agent-based architecture, you'll find actionable insights and lessons learned from the trenches.
