Senior AI Engineer — LLM agents, RAG & MCP in production
Cover image for notion-mcp-hono — Remote MCP server
notion-mcp-hono — Remote MCP server with a live playground Most MCP servers are local stdio scripts. This one is a remote, production-deployed MCP server for Notion — with a public playground where you can run the actual tools right now, no setup: notion-mcp-hono-production.up.railway.app (http://notion-mcp-hono-production.up.railway.app) What's in it: → Streamable HTTP transport on Hono, deployed on Railway — connectable from claude.ai (http://claude.ai) or Claude Code in under a minute → Bearer-token auth with timing-safe comparison; the demo playground runs server-side against a sandboxed workspace, read-only, rate-limited — credentials never touch the browser → Clean architecture: transport / MCP / Notion layers with dependencies pointing inward — the Notion integration is swappable without touching tool code → Five tools, Zod-validated, with descriptions written for the LLM that consumes them and errors translated into actionable messages → Built test-first (Vitest, mocked Notion API), conventional commits, MIT-licensed Try the live playground, or connect the server to your own Claude in one command — both on the site. Source: github.com/ldamoredev/notion-mcp-hono This is what I mean by taking AI systems from demo to production: not a bigger demo — the same engineering discipline you'd expect in any production service, applied to AI infrastructure.

Cover image for Hermes — Local AI Agent
Hermes — Local AI Agent OS with production-grade guardrails Hermes is a multi-actor agent system I built to run my own freelance operation: it scans job opportunities, scores them against hard criteria, and drafts proposals — but never sends anything. Every output lands in a drafts folder for human review. What makes it interesting as an engineering project: → Multi-actor architecture: specialized agents (opportunity radar, filtering, drafting) each running on the cheapest model that can do the job — volume tasks on lightweight models, premium models reserved for high-stakes output → Hard filters that are actually hard: no "when unsure, keep it" escape valves that let LLMs rationalize around clear disqualifications → Regression fixtures for prompts: every prompt change runs against a fixed batch of real-world cases before shipping — TDD discipline applied to agent behavior → Draft/approval mode by design: the system augments human judgment, it never replaces it → Built on the Anthropic SDK with structured context files (profile, rules, scoring criteria) as the agent's operating system Full architecture notes (in Spanish): ldamoredev.github.io/personal-agent-os-notes/es/ This project is my testbed for the patterns I ship to clients: agent systems that are cheap to run, safe to operate, and tested like real software.

Cover image for I built a tool that
I built a tool that reviews an entire software project and finds every bug, security hole, and problem — automatically. On its first run, it found 60+ issues in a live application, including ways an attacker could access other users' data. Then it fixed them, one by one, and verified nothing broke. Think of it as hiring a senior developer to inspect every corner of your code — except it takes minutes, not weeks. Claude Code · Python · Security Automation

Cover image for A client needed a system
A client needed a system where her students could book classes, pay online, and manage their schedules — and she needed to run the whole business from one place. I built it alone, start to finish. Teachers see their calendar, students pick a class and pay, the studio owner sees everything. Automated reminders, payment tracking, cancellation handling — all working, all live. One developer. One platform. Running in production. Next.js 15 · React 19 · TypeScript · Prisma · Supabase · PostgreSQL

Cover image for A 36-unit apartment building in
A 36-unit apartment building in Buenos Aires needed to stop chasing residents for payments over WhatsApp. I built a system that automatically sends each resident their expenses, what they owe, and when it's due. Clear numbers, on time, no phone calls. The building administrators went from spending hours every month on this to spending zero. Python · Django · Gmail API · PostgreSQL

Cover image for I needed a better way
I needed a better way to find and manage freelance clients. Nothing out there fit, so I built my own. It tracks every lead, every proposal, every follow-up. Then I added an AI assistant that searches job boards for me, finds the ones that match what I do, and puts them in my queue. It runs 24/7 and costs nothing. I open it in the morning and the opportunities are already there. Next.js · TypeScript · PostgreSQL · Ollama · Python
