Sarju H.

I build and maintain web and mobile applications with React, Next.js, React Native, and Node.js. I'm Top Rated Plus on Upwork, with 100% Job Success and $200K+ earned. I have 12+ years of development experience, including leading products from scratch and maintaining existing applications. I can join your engineering team or take responsibility for development across the frontend, backend, and deployment. I can help you with: - Building web applications and React Native mobile apps. - Adding features and fixing issues in existing React codebases. - Developing Node.js backends and integrating REST and GraphQL APIs. - Improving performance, reviewing code, and refactoring difficult-to-maintain areas. - Setting up deployment workflows and CI/CD. My stack includes TypeScript, Redux, Tailwind CSS, Express, NestJS, GraphQL, and Prisma. I also build desktop applications with Electron and Tauri. For an existing application, I'll start by understanding the codebase, current issues, and your priorities. For a new product, I will help turn the requirements into a practical development plan and work through implementation and release. Share what you're building, or where your current application needs help, and we can discuss the next step.
