Question 7

What makes a good developer portfolio in 2025?

Accepted Answer

A standout developer portfolio in 2025 should include: real commercial projects with measurable impact, AI-powered interactive features (like chatbots), structured data for SEO, responsive design with smooth animations, and clear calls-to-action. Nguyễn Xuân Hải's portfolio at hailamdev.space demonstrates these with GSAP scroll animations, Three.js 3D elements, and a Gemini AI assistant.

Question 8

Is React or .NET better for fullstack development?

React and .NET are complementary, not competing. React excels at building fast, interactive frontends while .NET Core provides enterprise-grade backends with C# and Entity Framework. Nguyễn Xuân Hải uses both together — React frontends with .NET Core APIs — in production platforms like Great Link Mai House (B2B) and VN Media Hub (CMS), demonstrating that the combination delivers scalable, maintainable fullstack applications.
