Building with Code & AI
I'm Ed Nunez. I write about machine learning, software architecture, and the evolving craft of building products with LLMs.
What You'll Find Here
This blog is a collection of deep dives, hard-won lessons, and practical patterns from building production systems over the last 15+ years. The focus has shifted recently — as it has for many of us — toward the intersection of traditional software engineering and the new AI-native workflows.
Background
I've spent my career building things that ship: distributed systems, real-time platforms, developer tools, and most recently, agentic AI systems. I've worked at startups, consulted for enterprises, and built my own products. The common thread has always been simplifying complexity — whether that's a microservices architecture or a prompt chain that actually works in production.
Current Focus
- LLM-Native Development — How AI changes the way we write, review, and ship code
- Agentic Systems — Multi-agent architectures with shared memory, kill switches, and audit trails
- Production ML — Taking models from notebook to reliable production service
- Developer Experience — Tools, workflows, and patterns that make building faster and more enjoyable
The Stack
This site is built with tools I actually use and recommend:
- Framework: Astro 5 — zero-JS by default, incredible for content sites
- Styling: Tailwind CSS v4 — native CSS variables, no config file
- Content: MDX with Astro Content Collections — type-safe frontmatter
- Fonts: Playfair Display (headlines) + Inter (body) + JetBrains Mono (code)
- Hosting: Self-hosted on Oracle Cloud (ARM), Nginx + Let's Encrypt
- Deployment: GitHub Actions → rsync → Nginx reload
