Testing Async Code — API Calls, Loading States, Error States

Hi, I’m Richa — a Senior Frontend Engineer with 5+ years of experience building scalable, production-grade web interfaces for enterprise and consumer applications. I work primarily with React, TypeScript, and modern frontend architectures, focusing on component systems, performance, and maintainability. Most of my experience comes from building real-world products in regulated domains like banking and insurance, where clarity, reliability, and long-term ownership matter more than quick demos. Through this blog, I write about frontend engineering fundamentals, scalable UI design, problem-solving, and the lessons I’ve learned working on large codebases. My goal is to share practical insights — not shortcuts — for developers who want to grow strong engineering foundations. I also mentor early-career developers and strongly believe that curiosity, asking the right questions, and understanding why something works are more important than memorizing tools. If you’re serious about improving as an engineer, you’re in the right place.
