About Thiago Reis
AI Prompt Engineer | LLM Systems | AI Automation | Software Engineer
Belo Horizonte, Brazil - 7:12 pm local time
I'm an engineer with a bachelor's and postgraduate degree, with experience across both large private companies and government projects. My work today focuses on applying Artificial Intelligence and Large Language Models (LLMs) to solve real business problems.
I design structured prompt systems, AI workflows, and automation solutions using tools such as ChatGPT, Claude, and Gemini. My background in software engineering allows me to approach AI not just as a tool, but as a scalable system that can be structured, tested, and optimized.
