Hi, I’m Kristine Valderosa, a backend-focused full-stack developer with strong experience in Django, Django REST Framework, PostgreSQL, and production-grade API development. I design robust backend logic, authentication workflows, and I build Vue 3 frontends using the Composition API, Pinia, and Tailwind CSS. I have 3+ years of web development experience, including 12 production Django/DRF applications in a long-term freelance role, plus ongoing full-stack work for a Virtual Labs web platform. I thrive working independently or across distributed teams, troubleshooting complex backend issues and delivering features across AWS-based integrations, Podman/Docker, and Nginx deployments. I am passionate about delivering reliable, scalable software and enjoy collaborating on architecture and product decisions, whether I’m tackling backend data stores, authentication, or frontend state management.
