Automate LinkedIn Outreach Messages Using AI and Python

Cold messages fail for a simple reason. They're not actually cold — they're warm in theory and cold in execution. You've researched the person, found something interesting, written what you think is a relevant opener. Then you send the same structure to 150 people and wonder why three reply. The bottleneck is drafting. Personalization takes time: reading a profile, finding a hook, writing an opener that references it, keeping the message short enough that someone actually reads it. Ten minutes per person, 200 people, do the math.

Build a Slack Bot That Answers Questions from Your Internal Docs [Part 2]

If you ran the bot from Part 1, you probably hit the timeout within the first few minutes. Someone typed `/ask`, got "This app didn't respond in time" in red, and trust died a little. Claude was still thinking. Part 1 treated the Slack app as a prerequisite — configured and ready. This part actually builds it. We'll create the app in the Slack dashboard, wire both tokens, fix the timeout with background threading, format answers with Block Kit so they look like a real bot response instead of a text dump, and add a `/reindex` command so the docs stay current without restarting the process. You'll need the code from Part 1 and a Slack workspace where you have permission to install apps.

Build a Slack Bot That Answers Questions from Your Internal Docs [Part 1]

The onboarding doc says the API key lives in the shared vault. The runbook says check the Confluence page. The Confluence page links to a Notion doc that was last edited two years ago. Every new team member goes through this. It's annoying, and it's solvable.

Building an AI-Powered Document Summarizer with Python and Claude API

I have about twelve PDF tabs open right now that I haven't read. A vendor comparison, two research papers, a spec doc from last week. At some point I'll get to them. Probably. Rather than actually reading them, I built a summarizer. This tutorial walks through the same thing: a Python script that takes any `.txt` or `.pdf` file from the command line and returns a clean summary using the Claude API. You'll need Python 3.10+, an Anthropic API key, and basic Python familiarity. No prior LLM experience required.

Choosing the Right AI Model: GPT-4, Claude, Gemini, or Llama?

The question comes up constantly. Someone wants to build a product or add AI to an existing one, and the first thing they hit is: which model? The advice online is mostly useless — half of it is sponsored, the other half is from someone who tested the models for two hours on their laptop.

RAG (Retrieval-Augmented Generation) Explained with Real-World Examples

LLMs have a memory problem. Ask Claude or GPT-4 about your internal documentation, this quarter's pricing changes, or a contract signed last week — and you'll get one of two outcomes: "I don't know," or something confidently wrong. RAG fixes this. Not by retraining the model. Not by fine-tuning. By handing the model the documents it needs, right before it answers.

Understanding LLM APIs: A Practical Guide for Web Developers

LLM APIs look like REST APIs but don't behave like them. If you've built integrations with Stripe or GitHub's API, you know the pattern: send a request, get structured data back, handle errors. LLM APIs follow that same HTTP shape, but they add a handful of concepts that don't exist in typical API work. Skip past them and you'll hit confusing bugs and unexpected bills.
