Custom Web App: SaaS, CRM & Internal ToolsGusti Faizal
I'll design and build a production-ready web application using Next.js, React, TypeScript, TanStack, and Tailwind CSS. Whether it's a SaaS product, CRM, internal tool, or any data-driven app, I build it from scratch with clean code you own.
Recent work:
Web app example 1
Web app example 2
Web app example 3
Web app example 4
What you get:
A fully functional web application with real data handling, authentication, and a UI your team will actually want to use. No bloated templates. Custom-built for your workflow.
Built for:
SaaS products and MVPs
CRM and client management tools
Admin panels and internal tools
Analytics and reporting platforms
Inventory, booking, and project management systems
Any data-driven web application
Tech stack:
Next.js + React + TypeScript
TanStack Query + TanStack Table for data-heavy UIs
Tailwind CSS + shadcn/ui components
Authentication (NextAuth, Clerk, or Supabase Auth)
Database integration (PostgreSQL, Supabase, or your existing backend)
Vercel deployment
My process:
Discovery: We map out your data model, user flows, and feature priorities
Design: High-fidelity Figma mockups of key screens
Build: Iterative development with weekly check-ins
Deploy: Production deployment with your domain and environment configured
I've shipped Faktur (invoice management with real-time calculations and PDF generation), Katalisk (creator workspace with scheduling and analytics), and Lamina (NFT portfolio tracker). Every project was built with the same stack I'll use for yours.
