About

I build intelligent data pipelines and AI systems that solve real production problems — not prototypes.

My background is in mission-critical infrastructure: years operating 24/7 environments where systems can't fail. That foundation separates the way I build from most: I understand deployment, reliability, and observability before a model or pipeline ever reaches production.

Today I focus on data engineering with AI applied at every layer — ETL pipelines, LLM systems, RAG architectures, and autonomous agents. Every project in this profile processes real data, runs in production, and solves measurable problems.

AI-augmented engineering is my daily workflow — Claude Code, Gemini CLI, GitHub Copilot, Cursor, OpenAI Codex, and Antigravity as active engineering partners, not just assistants.

Currently: Running a helpdesk analytics platform in production processing 21,000+ tickets across enterprise contracts (KFC · IMC) — real-time ingestion via Pipefy and InvGate webhooks, 5-layer SLA normalization, predictive breach analysis, and semantic classification with local LLMs (Qwen2.5 14B).


What I Build

Intelligent Data Pipelines High-performance ETL and analytics with FastAPI, DuckDB, Polars, and PostgreSQL. Real-time ingestion, incremental sync, and operational intelligence at scale.

LLM Systems & RAG Retrieval-Augmented Generation pipelines with semantic chunking, pgvector, reranking, and output quality evaluation. Built for production — not tutorials.

Autonomous Agents Multi-step agents with LangChain and LangGraph that handle real workflows: ticket triage, knowledge retrieval, incident response, and decision routing.

AI-Augmented Infrastructure MCP Servers, observability layers, and automation tooling that integrates LLMs into existing systems without breaking what already works.
