Jeff Barros
@jeffbarros
Software engineer fluent in 4 languages, expert in AI, LLMs, and prompt engineering. I ship real production code with AI, daily.
BrazilWhat I'm looking for
I'm an AI-native software engineer. I use LLMs and AI tools as my default way of working to audit code and pages, write and ship features, and build working software faster than doing it by hand ever allowed.
At TempoRevenue, I audit e-commerce stores for performance, checkout, and UX, using AI to speed up diagnosis, then build the fixes myself.
Before that, I built an Android security app in Kotlin from the ground up, using LLM-assisted workflows for architecture, code, and review. Earlier in my career, I designed structured prompt engineering workflows to self-publish two books, well before that was common practice.
Prompt design is a core skill for me, not a side trick. I know how to get a model to do real, reliable work, and how to build a repeatable process around that instead of one clever one-off prompt.
I work in Portuguese, Spanish, English, and German, and I'm looking for a remote role in software engineering, applied AI, or technical operations.
