Building a Local Semantic Search Engine - Part 1: What Are Embeddings?
"I love playing with my dog" and "My puppy is so playful and fun" are 80.4% similar. Compare that to "Cars are expensive to maintain"—only 45.5% similar. How does a computer know that? Embeddings—and I wanted to run them entirely on my laptop.
Building an MCP Agentic Stock Trading System - Part 7: MCP Experimentation Lessons
After building three AI trading agents with MCP, here's what I'd do differently.
Building an MCP Agentic Stock Trading System - Part 6: Cloud vs Local vs Rules
Building with three agent types taught me: you can optimize for speed, cost, or intelligence—pick two.
Building an MCP Agentic Stock Trading System - Part 5: Backtesting All Three Agents
I ran all three agents over 2 months of real market data to see how MCP handles different "brains" with the same tools. The results surprised me—but not in the way I expected.
Building an MCP Agentic Stock Trading System - Part 4: When Agents Disagree
Three AI agents analyze Apple stock on the same day. Two reach the same conclusion through reasoning, one through arithmetic. What does this reveal about AI decision-making?
Building an MCP Agentic Stock Trading System - Part 3: The Agentic Loop
The agentic loop is where LLMs become active problem-solvers instead of passive responders. The LLM doesn't just answer once—it iteratively calls tools, analyzes results, and decides what to check next. My trading agent uses this to analyze stocks: fetch data, calculate indicators, check trends, then make a decision.
Building an MCP Agentic Stock Trading System - Part 2: The MCP Servers and Tools
MCP servers are like USB hubs for AI—they provide standardized tools that any agent can plug into. My trading system has two: one fetches market data, the other calculates technical indicators. Write them once, use them with Claude, local LLMs, or even traditional code.
Building an MCP Agentic Stock Trading System - Part 1: The Architecture
I wanted to experiment with Model Context Protocol (MCP) and compare local LLMs against API-based ones. So I built a stock paper-trading system with three brains: a rules-based trader, Claude API, and a local Llama model in LM Studio. Same market data, different decision-making approaches.
Adding nano-banana 3 Support to My CLI Wrapper
Twenty-four hours after Google dropped nano-banana 3, I shipped support for it. New model, new resolutions (4K!), new features. This is what building with AI is like at this point in November 2025.
