Montevideo, Uruguay - 2:55 pm local time
What I've shipped (most recent):
— 3 custom MCP servers (case studies): mcp-linkedin (OAuth-as-MCP gateway), mcp-storage (R2 presigned passthrough — bytes never enter the model), source-fetchers-mcp (5 source types behind one interface, diff-mode for ~90% token savings on re-ingest). Happy to walk through any of them live.
— Promaker: custom MCP-powered debugging workflow → -68% mean debug time, 12 deploys/week, zero-downtime migration.
— Tradepulse: enterprise RAG with LangChain + pgvector → 200K+ docs indexed, 98% citation accuracy, -74% daily research time.
— Imanclicks: agent-powered marketing automation with LangGraph + OpenAI + Next.js → 5x campaigns/month, -82% landing-page cost, 23 hrs/week saved.
— Compass (current): BigQuery / Airflow pipelines moving millions of records/day for ads + marketing intel.
— Verifarma (5y): pharma track & trace deployed in 8 countries — 1B+ units tracked, zero regulatory penalties.
How I work:
Custom MCPs + Claude Code as the build loop, brain-local wiki as shared context across agents, replayable decision traces in an LGTM stack (Loki/Grafana/Tempo/Mimir) on K3s. MCP-as-passthrough for external auth — bytes don't pass through the model.
My take on tool layer:
Tool descriptions carry 80% of the contract. If a description is ambiguous, the agent picks the wrong tool — prompts above can't fix that. Descriptions own when-to-use, system prompt owns persona, orchestrator owns policy.
Stack I run today: Python, TypeScript, Go, Next.js, PostgreSQL/pgvector, BigQuery, dbt, Docker, Kubernetes (K3s), GCP, AWS, GitHub Actions. Claude SDK + Anthropic API daily driver. OpenAI when it fits the job. LangChain/LangGraph when the job calls for it — shipped in Tradepulse and Imanclicks.
Honest about depth:
I lead with custom MCPs + Claude Code; that's where I have the most production hours. LangChain isn't my daily driver but I've shipped it and am happy to work in a LangChain-heavy stack — just transparent on where my depth is. I pass on demos without a path to production.
