HEITOR QUEIROGA

Full stack developer with 5 years of experience building scalable web applications end to end: React.js, Next.js and TypeScript on the frontend; Django, Django REST Framework and Java with Spring on the backend. Today I lead the frontend team of a healthcare product compliant with HIPAA and GDPR.

I have a track record of delivering MVPs on tight deadlines, optimizing performance for thousands of simultaneous users and evolving systems already running in production. I work with Docker, CI/CD and cloud deployments (AWS and Google Cloud), with advanced English and experience in internationally distributed teams.
