Project details
I help founders and startups turn their SaaS ideas into live MVPs quickly. Using React.js or Next.js with Tailwind CSS, I create modern, responsive frontends powered by robust backend APIs in NestJs , Node.js (Express) , PHP , Laravel based on what suits your product best.
Authentication is handled with JWT, OAuth2, or Firebase Auth. Your app will include a fully working database (PostgreSQL, MySQL, or MongoDB), along with core features like admin panels, role-based access, and real-time REST or GraphQL APIs. The architecture is modular, clean, and built to scale as your product grows.
I also manage deployment on Vercel, Heroku, or Railway, and can implement CI/CD using GitHub Actions for seamless updates. Every build is mobile-friendly, performance-optimized, and integration-ready.
Typical delivery: 10–30 business days, depending on project scope.

quality test on streaming site
Surinder helped me set up a site and the i nteraction with him if very professional. Many freelancers have weak business manners but not Surinder. He pays attention to detail, he knows how to communicate and does it well. He is a fine collaborator and is very cooperative. He used React and NestJS very effectively and the result is above my expectations. Give this man your work, it will turn out fine.
