Diana Vanessa Castillo

I’m a Software Engineer specializing in scalable and accessible front-end systems, with a focus on React.js and TypeScript. I deliver secure, production-grade applications in global Agile environments, and I’ve contributed to projects that use AI-assisted development and AI-powered features. I’m especially known for rapid technical ramp-up, cross-functional collaboration, and owning complex features from architecture to deployment.

At Accenture Philippines, I developed enterprise-scale front-end applications in Agile teams, helped shape maintainable and scalable component design through architectural discussions, and integrated AI-powered features into business workflows. I also implemented WCAG-compliant accessibility standards to improve usability and regulatory alignment. Previously at Samsung R&D Institute Philippines, I quickly transitioned into React-based enterprise development, delivered production features within the first month, created reusable secure UI components aligned with internal security policies, and led knowledge-sharing to elevate team coding standards.
