Project details
I will build a scalable multi-tenant SaaS platform designed for startups, B2B products, internal tools, and enterprise applications.
You'll get secure SaaS platforms using Next.js, TypeScript, PostgreSQL, Supabase, and modern cloud infrastructure. Your platform can include organization workspaces, role-based access control (RBAC), subscription billing, team management, analytics dashboards, and custom business workflows.
The architecture is designed to support growth from early customers to enterprise-scale usage while maintaining performance, tenant isolation, and security.
Whether you're launching a new SaaS product or rebuilding an existing system, you'll receive a maintainable, production-ready codebase built using industry best practices.

Exceptional developer! The Stripe setup was flawless, and they went the extra mile to fine-tune every aspect for performance and user experience. A truly top-tier developer who makes complex work look effortless. Couldn’t recommend more highly.

Migrate from legacy authentication to NextAuth + Update some APIs
I'm working with freelancers for over 12 years on all platforms and i never had such a great experience. He thinks and helps you like he's your real partner, not someone you hired. Absolute pleasure to work with, highly knowledgeable and professional at all times. Great attention to detail and prepared to help you on every step with recommendations so you feel safe all the time. I will hire him again for sure.

Help me complete the project over the weekend (Next/Node), up to 6$/h only
What an exceptional experience this was! Muhammad is a magician at work. You mostly work with juniors, have sometimes a chance to work with some seniors, but this guy is two steps above seniors. If you have any work on backend, this is the guy you want to have. No AI, the code is clean and he is incredibly fast. We have already scheduled another project with him. Highly recommended.
