John C
About this gig
Need a custom CRM, internal admin dashboard, or business portal tailored specifically to your companys workflow?
Off-the-shelf software is often bloated, expensive, and rigid. I build modern, lightning-fast internal tools and custom CRM solutions using Next.js, Node.js, FastAPI, and Supabase/PostgreSQL that streamline operations and scale with your business.
️ What I Build:
- Custom Admin Dashboards: Real-time analytics, dynamic charts, data tables, and export features (CSV/PDF).
- Custom CRM Systems: Lead tracking, customer management, automated pipeline stages, and communication logs.
- Role-Based Access Control (RBAC): Secure authentication with granular permissions (Admin, Manager, Client, Staff).
- Backend & API Integrations: Fast REST/GraphQL APIs, webhooks, and third-party service connections (Stripe, HubSpot, Zapier, Twilio).
- ️ Database Architecture: Secure PostgreSQL/Supabase setup with efficient query indexing and data integrity.
Why Choose My Backend & CRM Service?
- Tailored to Your Operations: Built 100% around your specific business logicno unnecessary features.
- Enterprise-Grade Security: Encrypted database connections, strict authorization layers, and secure token management.
