Next.js & Node.js Developer | SaaS Architecture & Serverless Backend
100% Job Success
5.0  (5 reviews)
Cairo, Egypt - 7:18 am local time
Next.js + Supabase developer with deep backend roots. I've built production SaaS from the ground up, multi-tenant architecture, RLS, offline-first PWAs, serverless backends. Top Rated. 100% Job Success Score. 8 contracts, zero disputes.

Here's what that looks like in practice:

→ Built Crewmark from scratch, a multi-tenant B2B dispatch SaaS on Next.js + Supabase with PostgreSQL Row Level Security enforced at the database layer, not the app layer. Offline-first PWA for field crews using Service Workers and IndexedDB. Custom stateless passcode auth designed for low-literacy workers. Webhook billing across Paddle, Square, and Creem.

→ AWS serverless backend handling 10,000+ daily requests, Lambda, API Gateway, Cognito, S3. BullMQ + Redis workers running OpenAI classification ran 8 months without a single restart.

→ Real-time platform rebuilt for 200+ concurrent users, Pusher WebSockets, RBAC with Admin/Super Admin/Owner tiers, Stripe webhook-driven privilege unlocking. Zero downtime during cutover.

→ Production security operations PWA for a European firm, TOTP MFA for privileged roles, push notifications via Service Workers, i18n for multilingual staff, client-side PDF report generation. Live and internal.

→ LLM gateway governing Anthropic and OpenAI usage, streaming cancellation, token capping, kill-switches, 12-point AI content validation pipeline with automatic regeneration.
Next.js SaaS: App Router, Server Actions, multi-tenant RLS, Supabase Auth and Storage, Edge Functions, SSR. Backend: Node.js REST APIs, BullMQ, Redis, AWS serverless from zero to production. Payments: Stripe and Paddle, subscriptions, webhooks, seat-gated access. AI: OpenAI, Anthropic Claude, RAG pipelines, LLM gateways. Real-time: WebSockets and Pusher. Offline-first PWAs with Service Workers and background sync.

What I don't do: disappear mid-project, ship code that works on my machine and breaks on yours, or pass off AI-generated scaffolding as engineering.

If you're a founder or technical lead with a Next.js or Supabase project, message me with what you're building. I'll tell you clearly whether I can help and what it will take.

Steps for completing your project

After purchasing the project, send requirements so Nabil can start the project.

Delivery time starts when Nabil receives requirements from you.

Nabil works on your project following the steps below.

Revisions may occur after the delivery date.

Project Requirements Review

I’ll carefully review your project needs, suggest improvements, and confirm missing details before coding begins.

Frontend Development

I’ll build a responsive React frontend (Tailwind/Material UI or your preferred UI framework) with routing and reusable components.

Review the work, release payment, and leave feedback to Nabil.
