You will get A Production-Ready SaaS MVP | Next.js, NestJS, Stripe, Auth & PostgreSQL
Top Rated
Project details
You have a SaaS idea. You need an engineer who owns the outcome —
not a feature factory, not a vibe coder.
I build production-grade SaaS platforms: React/Next.js frontend,
NestJS backend, PostgreSQL database — shipped with Stripe billing,
JWT auth, role-based access, admin dashboard, and clean UI.
Production-ready. Not a demo.
✅ Next.js + TypeScript + Tailwind frontend
✅ NestJS backend with modular architecture
✅ PostgreSQL with relational schema design
✅ Stripe subscriptions, webhooks, billing portal
✅ JWT auth + role-based access control
✅ Multi-tenant architecture (separate workspaces)
✅ Admin dashboard — users, subscriptions, activity
✅ Docker + Vercel/AWS deployment
✅ Source code, docs, 7-day post-launch support
My first Upwork client: "Solved a critical concurrency problem in
our multi-tenant SaaS platform involving race conditions and partial
write failures. Production-ready from day one."
Previously: senior engineering roles at Dubizzle, Systems Limited,
Sumerge, and Motive Inc. You're getting four years of that
experience at freelancer rates.
Message me before ordering — I'll tell you exactly which tier
fits your scope. 100% Job Success Score. No overbilling.

Deterministic Conflict Resolution for Concurrent Actions in a Multi-Tenant SaaS System
Exceptional full-stack JavaScript engineer. Solved a critical concurrency problem in our multi-tenant SaaS platform involving race conditions and partial write failures. His Node.js backend architecture was scalable, secure and production-ready from day one. Communicated clearly, flagged issues proactively and delivered on time. If you need a senior full-stack developer for SaaS architecture or backend systems he is the one to hire

If you have found yourself in one of these situations:
You need an MVP but cannot afford 6 months of back-and-forth.
You launched but retention is low and you do not know why.
Your current codebase is becoming a liability instead of an asset.
You need one engineer who can own the full product, not a committee.
Then you are in the right place.
WHAT I ACTUALLY DO
I am a Full-Stack JavaScript Engineer with 6+ years of experience building scalable SaaS platforms, cross-platform mobile apps, and revenue-generating web products — from zero to launch and from launch to scale.
I work across the entire product surface. React and Next.js on the frontend. Node.js and NestJS on the backend. React Native for iOS and Android. PostgreSQL, MongoDB, Firebase or Supabase depending on what the product actually needs.
I do not hand off. I do not disappear after delivery. I stay accountable to outcomes.
HOW I THINK DIFFERENTLY
Most developers optimize for shipping features. I optimize for what happens after the feature ships. Does it retain users? Reduce churn? Drive upgrades? Create stickiness?
Every architectural decision I make is tied to a product outcome. Faster load times are not a technical metric — they are a conversion metric. A clean API is not elegant code — it is faster iteration for your team. Choosing the right database is not about preference — it is about the query patterns your product will actually demand at scale.
This is what I mean when I say I build products, not just applications.
WHAT CLIENTS WORK WITH ME ON
SaaS platforms — subscription products, multi-tenant architecture, billing integration
MVP development — from validated idea to live product, fast
Cross-platform mobile apps — iOS and Android with a single React Native codebase
Web applications — dashboards, admin panels, internal tools, customer-facing platforms
API development and third-party integrations — Stripe, Firebase, REST, WebSockets
Performance and scalability work — when your current stack is starting to crack
THE STACK
Web: React, Next.js, Angular, Node.js, NestJS, Express, Python (Django, Flask)
Mobile: React Native for iOS and Android
Databases: PostgreSQL, MongoDB, Firebase, Supabase, SQL
Cloud and DevOps: AWS, Docker, CI/CD pipelines
Auth and Payments: Stripe, Supabase Auth, Firebase Auth, JWT
AI Integrations: OpenAI APIs, LLM integrations, AI automation, chatbot integrations, AI-powered workflows
BEFORE WE WORK TOGETHER
I am selective about projects because I commit fully to the ones I take on. I work best with founders and product teams who have a clear problem to solve, respect engineering judgment, and want a long-term partner — not just a ticket-closer.
If that sounds like you, send me a message and tell me what you are building. I will give you an honest, direct assessment of what it takes and whether I am the right fit.
Steps for completing your project
After purchasing the project, send requirements so Maaz can start the project.
Delivery time starts when Maaz receives requirements from you.
Maaz works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & Architecture Planning
I review your requirements and define the data model, API structure, and feature scope. You'll receive a brief technical plan confirming what will be built before any code is written.
UI Design & Core Feature Development
Build the UI using your provided designs or a clean component library. Develop all agreed features — user flows, API endpoints, Stripe billing, role-based access, and admin panel in parallel.
