About Me
Software engineer based in Brazil with about 6 years building products remotely. I care about clean APIs, predictable state, and UIs that stay fast under real load. Lately, most of my work has focused on putting LLMs into real product workflows: prompt evaluation systems, AI-assisted editors, and automation pipelines that save hours of manual work.
