Every AI call I make goes through a Prompt Architect before it reaches the model. The Architect takes my rough prompt, sends it to Ollama for structural analysis, then to Kimi K2.6 for refinement, and returns a version with clearer constraints, better role framing, and tighter output instructions.

Prompt injection is a real attack vector that most developers ignore until something goes wrong. I learned this when reviewing my LinkedIn auto-responder and realizing that a malicious commenter could write "ignore previous instructions" and potentially manipulate the AI response.

I built an ITIL incident system powered by Ollama

Every incident on my server creates an ITIL-style ticket in PostgreSQL automatically. Not because I work at an enterprise. Because structured incident tracking is how you stop making the same mistakes twice.

My AI agent runs daily competitive research while I sleep

Every morning at 7am Regina time, my server runs a competitive intelligence report while I sleep. It scrapes competitor sites, checks their pricing pages, monitors for new features, and summarizes changes. The summary lands in my Telegram before I check my phone.

Caddy replaced Nginx for me and I'll never go back

I used to manage SSL certificates manually with Nginx and Certbot. Every 90 days, renewals. Every new service, 20 minutes writing proxy config. I once took down a site for 3 hours because I got the upstream block wrong.

I have 14 services running on one server. Every single one has database passwords, API keys, and credentials in environment files. The thought of those sitting as plain text on disk kept me up at night.

I built a self-healing server that fixes itself while I sleep

I used to get woken up at 3am by server alerts. Half the time I would check and the issue had already fixed itself in 90 seconds. I was losing sleep over false alarms.

Why I chose PM2 over Docker for most services - SolidNorth

Jay Tuazon — Thu, 25 Jun 2026 08:12:19 +0000

Why PM2 over Docker for most services

Running 13 production services on a single VPS. Here is what I learned about overhead vs simplicity.

Docker adds ~50MB overhead per service. PM2 adds ~5MB. When you are on a 16GB box with 13 services, that math matters.

For stateless Node/Python apps that do not need isolation: PM2 wins on simplicity, startup time, and memory.
