Project details
I'm Andy, founder of RZS-IT — a development agency that builds production-ready SaaS products for founders and businesses who can't afford technical debt.
Most MVP agencies deliver something that works in a demo but breaks the moment real users hit it. We build differently: clean architecture, proper multi-tenant data isolation, real Stripe billing, and a codebase designed to support the next 10 features without a rewrite.
Your MVP includes everything needed to acquire and charge your first paying customers: authentication, subscription billing via Stripe, a functional dashboard, your core feature set, and transactional emails for every key event. Deployed, documented, and ready for users.
I've built SaaS products for B2B service platforms, e-commerce tools, and field operations software. I understand the difference between an MVP that validates your idea and one that embarrasses you in front of early customers.
Delivery includes full source code, Supabase project setup, Stripe configuration guide, and a 30-minute walkthrough call so you understand every part of what was built.

About Sirbu
Full Stack Developer React Supabase Custom ERP and Web Apps
Bucharest, Romania - 8:16 pm local time
If your business runs on spreadsheets and manual workflows, I build the system that replaces them — without breaking your operations in the proces.
We specialize in:
- Custom ERP systems for service industries (installation companies, construction, facilities)
- E-commerce platforms with complex inventory and logistics requirements
- B2B SaaS applications built for scale
Our stack: React 18, TypeScript, Node.js, Supabase, Tailwind CSS — modern,
maintainable, and battle-tested.
We don't do prototypes or MVPs that break at scale. We build systems that handle
real business operations from day one. Clean code, clear documentation, zero surprises.
Currently working with clients across Romania and Western Europe. Available for
long-term partnerships and complex technical projects.

Delivery time starts when Sirbu receives requirements from you.
Sirbu works on your project following the steps below.
Revisions may occur after the delivery date.
Scope & architecture
Finalize feature list, database schema, and Stripe plan configuration. Set up Supabase project, GitHub repo, and dev environment.
Auth & billing
Implement authentication (email, OAuth), Stripe subscriptions, webhooks, and customer portal. Core infrastructure first.
