BrazilSenior Full Stack Developer at Zipdev
About
At Zipdev, I built backend and frontend LMS capabilities and architected AI workflows for student risk analysis, quiz generation, and course creation. I reduced average delivery time from about 35 days to 7 days by redesigning the engineering workflow and clarifying team ownership.
I've designed architectures, APIs, integrations, cloud infrastructure, and legacy modernization across Tok&Stok, Deliver IT, UOL EdTech, Moove, Kaizen, Zipernet, and Reweb. I'm focused on production AI systems using OpenAI, Anthropic, and Gemini APIs, while mentoring developers and turning complex product requirements into practical software.
