About Luís

I help teams automate business workflows using AI, LLMs, APIs and enterprise data.

My background is in enterprise integrations, backend services, REST APIs, SQL/PLSQL and Oracle Retail systems. I have experience connecting business systems, transforming data, consuming APIs and working carefully in production environments.

I’m focused on AI automation and LLM integrations: GPT/Claude-based workflows, document assistants, ticket/email classification, data extraction and API-based automations.

I like to start small: understand the process, define inputs and outputs, build a working prototype, validate with real examples, then improve reliability with logs, human review and clear error handling.
