About this gig
SaaS Builder | Startup MVP Expert | Admin Dashboard Specialist | Secure API Engineer
I build scalable, production-ready SaaS applications using Next.js, React, and NestJS, focused on performance, security, and clean architecture. From idea to launch, I help startups and businesses turn concepts into reliable, high-quality products.
I specialize in admin panels, analytics dashboards, and multi-tenant SaaS systems, with smooth filtering, reusable UI components, and modern UX. My backend systems follow API-first design, secure authentication, and role-based access control (RBAC) to ensure safety and scalability.
What I deliver:
Responsive frontend (Next.js / React)
Robust backend (NestJS / Node.js)
Secure auth & authorization
REST APIs with Swagger docs
MongoDB & scalable data models
Clean, modular, maintainable code
Advanced features:
Zod validation, React Hook Form, TanStack Query, shadcn/ui, jsPDF (PDFs & invoices), Zapier automations, Sentry error tracking, idempotent APIs, and Git-based quality checks.
If you need a startup MVP, admin dashboard, or full SaaS platform, I'll deliver a polished, scalable solution built with modern engineering best practices.
