Stop Building Separate Vector Databases for AI Features, Your Postgres Already Can Do This

Three months ago, I watched our DevOps lead spend two days debugging why our analytics team's queries kept timing out. They'd asked a simple question: "Which customer segments have the highest churn?" What should have taken five minutes turned into a back-and-forth with the data...

I Spent 6 Months Using LLMs Without Understanding Them, Here's What Changed

I remember the exact moment I felt like a fraud. I was in a code review, confidently explaining how I'd integrated GPT into our Django app using the OpenAI API, when a junior dev asked: "But how does it actually know what to do?" I stammered something about "neural networks" and...

Everyone's Building Shopping Bots. Nobody's Building Shopping Systems.

Last month, I spent three days debugging why a payment confirmation email went to the wrong customer. Not the wrong inbox, the completely wrong person. The order was placed correctly. The payment went through correctly. But somewhere in the state transitions between "payment appro...

Stop Treating Your LLM Provider Like It's Forever

I spent three weeks last month ripping out Anthropic-specific code from a review automation system we built for a logistics company. Three weeks. The work itself took maybe two days, the rest was tracking down subtle differences in how we'd structured prompts, handled errors, and...

Stop Treating LLMs Like Magic: Here's What Actually Happens Inside

I spent three hours debugging why Claude was giving inconsistent responses to structurally identical prompts last month. Same input, different outputs. My first instinct? Blame randomness. My second instinct? Blame the API. My actual problem? I had no mental model for what was ac...

Stop Confusing Your Crawlers: Three Files, Three Jobs (And Why I Kept Breaking Mine)

I spent an embarrassing amount of time last year debugging why my blog posts weren't appearing in Google search results. I had a beautiful sitemap. I had a robots.txt file. I thought I was doing everything right. Turns out, I was conflating three completely different concerns int...

When Your API Does Something Completely Different Than You Thought (And That's Actually Fine)

I was integrating Stripe's payment API last month when I realized I'd been approaching webhooks entirely wrong for three years. Not catastrophically wrong, my systems worked, but I was fighting the API instead of working with it. Reading through ReelCraft's architecture today remin...

I Built My Own Agent Control Plane So You Don't Have To (But You Probably Will Anyway)

Last month, I watched a startup I know spend three weeks trying to move their Claude-based agent to AWS Bedrock. Three weeks. Not because the agent logic was complicated, it wasn't. But because their entire infrastructure assumed Claude was the runtime. Credentials were hardcoded....

Stop Pretending You Understand LLM Terms Without a Map

Last month, I was reviewing a pull request where someone had implemented token streaming for our chatbot API. The comment in the code said "reduces latency by 40%." I nodded and approved it, but honestly? I had no idea why tokens specifically mattered, or what a KV cache even was...

I Built an LLM Feature Without Token Limits. It Cost Me $900 in Two Days.

Last month, I deployed a customer support chatbot that seemed innocuous enough. Simple retrieval, straightforward responses, nothing fancy. By day two, the AWS bill had spiked by nearly a grand. I spent an hour debugging before I realized the problem: I wasn't limiting conversati...
