LLM routing per tier via OpenRouter — when one model doesn't fit all

📦 Full runnable example: github.com/sm1ck/honeychat/tree/main/tutorial/02-routing — docker compose up exposes POST /complete on localhost:8000. Every snippet below is pulled from that repo. Most introductory "chat with AI" tutorials pick one model and call it a day. That works in a toy. It stops being enough in production, where users have different price sensitivity, different conversation sty...

Why Your Image Pipeline Breaks at 3am and How to Fix It

The 3am Alert You shipped the image pipeline months ago. It worked in staging. It worked the first week in production. Then one morning at 3am, your phone buzzes. The container is dead. Memory usage spiked to 4 GB, Kubernetes killed the pod, and the queue backed up to 12,000 unprocessed images. You SSH in, restart the service, and go back to bed. Two days later, it happens again. Diffe...

Sheet Generation from JSON: Replacing Manual Spreadsheet Assembly

The Spreadsheet Assembly Line Nobody Wants Every operations team has at least one person whose unofficial job title is "the one who builds the spreadsheets." Financial close rolls around, and someone spends two days copying numbers from the system into Excel, formatting columns, adding SUM formulas, making sure the currency symbols are right, and emailing the finished file to five peopl...

Replacing Puppeteer, Sharp, and Tesseract with One API

The Stack That Seemed Like a Good Idea Every developer who processes content has built some version of the same stack. Puppeteer for PDF rendering and screenshots. Sharp or ImageMagick for image transformation. Tesseract for OCR. Maybe wkhtmltopdf or LibreOffice thrown in for good measure. Each tool solves a real problem. Each tool works in isolation. And each tool becomes a maintenanc...

Generating PDFs from JSON Instead of HTML: Why Templates Are a Dead End

The HTML-to-PDF Pipeline Everyone Regrets You need to generate PDFs. Invoices, contracts, reports, certificates — the kind of documents businesses send to customers, partners, and regulators. The obvious approach is the one every team reaches for first: write an HTML template, inject data with a templating engine, render it to PDF with a headless browser. It works. For a while. Then s...

Building Multi-Tenant Document Pipelines: Architecture Guide for Agencies

The Five-Client Problem You run an agency. You have five active client projects, each with a document processing pipeline. Client A processes supplier invoices for a fleet management company. Client B extracts data from insurance claims. Client C generates branded PDF reports for a real estate platform. Client D transforms product images for an e-commerce marketplace. Client E does all ...

One n8n Node for Your Entire Document and Image Pipeline

The Three-Service Pipeline Problem You need to process invoices in an n8n workflow. So you wire up Mistral OCR to extract the text, GPT-4o to structure it into JSON, and a Google Sheets node to store the results. Three services, three sets of credentials, three billing accounts. The OCR costs per page, the LLM costs per token, and every run burns credits on both. Then someone asks you ...

Unpopular Opinion: Do not use OpenClaw...not yet.

This is a submission for the OpenClaw Writing Challenge Context This is going to be short post. The goal to is for me is understanding OpenClaw and to see why people use OpenClaw.

Challenge : 4 System-Level Challenges in Developer Experience (DevEx) Design

One of the most critical challenges in Developer Experience (DevEx) design is operating at the system level rather than the interface level. DevEx is not simply UX applied to a technical domain—it requires designing across a distributed ecosystem of tools, infrastructure, and workflows. Unlike traditional UX, where the focus is a single product or interface, DevEx involves understanding how devel...

Pygame Snake, Pt. 3

Part 2 left off with a square moving on a grid. Now, let's take control of it by consuming KEYDOWN events. One simple approach would be to have a variable that represents one of the four directions the snake can go. It might use values 0-3, or it could use string literals like "up" and "left". A slightly more advanced technique would be to use the Vector2 class. We use pygame's Vector2 to keep t...

We’re Not Solving Problems Anymore

I've been developing for two decades: web things, applications, games, scripts, plugins... whatever my curiosity led me to. What always drove me was creating. As in, there was nothing, and now there is something I can use. I also like puzzles. As, I guess, most developers do. How to architect code. How to put things together. How to do X when Y happens. These are things we (used to?) do every day...

How anagram solvers actually work: algorithms behind the scenes If youâ€™ve ever built a word game or a tool to help with Scrabble, youâ€™ve likely run into the "anagram problem." Given a string of characters, how do you efficiently find every valid word in the dictionary that can be formed using those letters?

I've been a developer since 2010. 16 years building software for companies. 2 years freelancing. I've shipped production apps, worked with teams across different domains, handled real infrastructure at scale. I'm not new to this. What I clearly don't know yet is how to sell things. What I'm new to is building for myself — no client, no salary, no guarantee anyone will ever pay for what I make. Th...
