You will get secure authentication: JWT, OAuth, roles, and Supabase RLS
Project details
You will get authentication done right, once - so it stops being the part of your product you are afraid to touch. Weak auth is the most expensive mistake a SaaS can make: one breach costs more than every shortcut ever saved. I build it properly: JWT sessions, OAuth social logins, role-based access, multi-tenant permissions and Supabase Row Level Security policies - documented so you understand what each rule does and why. I have built auth from scratch (Spring Security) and on managed platforms. Includes a written summary so the next developer, or future you, is never guessing.

Frequently asked questions
About Muhammad
Full Stack Developer | SaaS & Stripe Payments
Karachi, Pakistan - 2:20 am local time
How many customers did you silently lose this month?
Most SaaS products don't die at the idea stage - they die between "the demo works" and "a stranger's card gets charged." Leaking payments. Taped-together auth. A developer who vanished at 80%.
If that sounds like your Tuesday, maybe I'm exactly who you need. I'm Muhammad Suhaib - Full Stack SaaS Developer. One owner, end to end:
· SaaS MVP from scratch (React/Next.js, Node/NestJS, Spring Boot)
· Stripe integration & payment-leak fixes
· Secure auth (OAuth, magic links, JWT, Supabase RLS)
· AI features (Claude API, speech-to-text, LLM integrations)
· Taking over half-built, messy codebases
My proof is live, not claimed: I run Zeplio, built Trustify, shipped an AI voice app - Stripe wired through all three, real paying users maintained daily.
Send your spec, Figma, or repo - within 48 hours you get a free written breakdown: where it leaks, what breaks at scale, what I'd fix first. No call, no obligation.
Building SaaS that charges cards, not just demos.

P.S. Most freelancers show you portfolios. I'll show you a product with real users that I built, deployed, and maintain myself. Judge the craft before you spend a dollar.
FAQ
Q: My product is half-built by someone else. Can you take it over?
A: Yes. Codebase audits, RLS tightening, Stripe flow repairs, and finishing roadmaps on existing Next.js/Supabase/Node projects are a core part of what I do.
Q: Can you build my MVP from scratch?
A: Yes, that's the sweet spot. Idea to launch: frontend, database, auth, Stripe subscriptions, deployment. You get a product real users can pay for, not a prototype that needs rebuilding later.
Q: How do I know you won't disappear halfway like the last developer?
A: Fair question - it's the exact fear that brought most of my clients here. Two things protect you: everything I build lives in your repo and your accounts from day one, and every milestone ships with a plain-words handover doc. If I vanished tomorrow, any developer could pick up cleanly. You're hiring an owner, not a hostage situation

Core Auth
Secure login with JWT sessions and password handling that follows current best practice - no shortcuts.
