Khalid Hossain User

I’m a frontend engineer with around 4 years of experience building and leading delivery of production React and Next.js products. I own work end to end—from client requirements through architecture, build, and launch—and I lead cross-functional teams of up to ten under real deadlines.

I build reliable, AI-integrated interfaces with a strong focus on accessibility and robust user flows. I personally architect and deliver the hardest subsystems (guarded multi-step flows, AI-integration reliability layers, and secure document delivery pipelines), set frontend standards with feature-based architecture and strict server/client separation, and ship with a disciplined TypeScript + tooling workflow (Husky/ESLint/Prettier/Jest).
