Spring AI MCP Server: Exposing Your Spring Boot App to AI Agents
Build production MCP servers with Spring AI. Step-by-step tutorial with @McpTool, security patterns, transport choices, and guardrails from day one.
Spring AI Agent Loops in Production: Tool Calling, Memory, and Guardrails — What Actually Works After 3 Months
I built a production agent with Spring AI — ReAct loops, tool calling, conversation memory, and token budget guardrails. Here's the code that survived real traffic and the $47K mistake I learned from.
What 3 Months of Kubernetes AI Gateway Taught Me About Gateway API's Real Purpose
I ran LLM traffic through Gateway API for 3 months. Token-based rate limiting, model-aware routing, and the Inference Extension changed how I think about Kubernetes networking entirely.
I Turned PostgreSQL Into a Multimodal Search Engine With pgvector — Here's How
Text, images, and audio — all searchable with one SQL query. I built a multimodal search pipeline using Gemini Embedding 2 + pgvector 0.8.0, and the results surprised me. Here's the real code, real gotchas, and when this actually makes sense.
Spring AI + RAG in Production: Structured Output, Ollama, and pgvector — What Actually Works
I built a production RAG pipeline with Spring AI, Ollama, and pgvector. Here's the structured output pattern, local dev setup, and the hybrid search approach that survived 6 months of real traffic.
Claude Code vs Open Source AI Coding Agents — I Tested Them All for 30 Days
I spent a month running Claude Code alongside OpenCode, Aider, Cline, Codex CLI, and Gemini CLI. Here's the honest comparison — benchmarks, pricing, real developer experience, and which one actually replaces Claude Code.
Why I Stopped Using LangChain4j for Spring Boot APIs — And Started Using Spring AI
I spent weeks building a RAG pipeline with LangChain4j before switching to Spring AI. Here's the honest comparison — auto-config, pgvector, and why staying in the Spring ecosystem saved me from framework glue code.
HNSW vs IVFFLAT in pgvector: I Benchmarked Both, Here's What Actually Matters
IVFFLAT and HNSW are the two index types in pgvector. I benchmarked both on 500K embeddings — the winner depends on your workload, not the hype.
PostgreSQL Vector Search: pgvector Tricks I Wish I Knew Sooner
You don't need Pinecone or Weaviate. PostgreSQL with pgvector handles vector search, hybrid queries, and semantic retrieval — and it's already in your stack.
My Honest Take on AI Coding Assistants in 2026
After 2 years of daily use across ChatGPT, Copilot, and Cursor, here's what actually helps, what hurts, and when to use which.
