I will build a custom ai saas platform or mvp as a senior full stack developer


About this gig
Looking for a senior full stack developer to build or fix your SaaS platform, web application, or AI powered MVP? I have 14+ years of experience delivering production-ready software with Laravel, PHP, Vue.js, React, and Next.js.
I can help you with:
- SaaS platform and MVP development from idea to launch
- Custom web application development, full stack
- AI powered features with the OpenAI and Claude API
- Multi-tenant architecture and role-based access control (RBAC)
- REST API development, webhooks, and third-party integrations
- Stripe payments and subscription billing
- Admin panels, dashboards, and reporting
- CRM, ERP, and custom business software
- Database design (PostgreSQL, MySQL, Supabase, Redis)
- Review, bug fixes, optimization, and scaling of existing SaaS Cloud deployment (AWS, DigitalOcean, Vercel)
Choose Basic for a quick review, critical bug fixes, and a roadmap. Choose Standard for a full stack SaaS MVP. Choose Premium for a complete AI powered, multi-tenant SaaS platform.
You get clean, scalable, maintainable code, clear communication, and regular progress updates. Not sure which package fits? Message me before ordering and we will find the right scope.

What can I get in the Basic package?
Up to 10 hours of work: a review of your SaaS or idea, critical bug fixes, optimization, and a clear roadmap with next steps.
Can you add AI features to my SaaS?
Yes. I integrate the OpenAI and Claude API for assistants, automation, and AI-assisted workflows, with human review where needed.
Do you build multi-tenant SaaS with subscriptions?
Yes. I build multi-tenant architecture, role-based access control, and Stripe subscription billing as part of the Standard and Premium packages.
What if my project needs more than the package scope?
I will tell you early. We can add hours, order Gig Extras, or move to a larger package, with no surprise costs.
