Senior Backend Engineer at RegMetrics, building AI-assisted medical device compliance workflows and an NLP standards recommendation engine.

Brazil

Message

At RegMetrics, I develop Python, Django, and Wagtail APIs and CMS features for AI-assisted medical device compliance workflows. I built an NLP engine that matches device profiles with ISO metadata and integrated Gemini agents to generate regulatory content tailored to each client.

Previously, at Seazone, I optimized critical endpoints for up to 90% faster data access and implemented Celery for asynchronous integrations. Across fintech, agritech, and healthtech, I’ve worked on distributed systems and AWS infrastructure, with a focus on code quality and shipping things that work.
