Aayush Mandora
Full-Stack Developer
I help startups ship production-grade SaaS and marketplace platforms fast. Every app I've built is live on the Play Store and handling real users.
About Me
My strongest area is backend architecture: designing systems that handle multi-vendor order splitting, in-app wallets with ACID transactions, role-based access control, and real-time status cycles with multiple stakeholders. I don't just build APIs, I understand the business logic behind them and build systems that are maintainable and scalable from day one.
What I'm great at
- Multi-vendor order splitting & management
- In-app wallet systems with ACID compliance
- Role-based auth & master admin panels
- Geo-based vendor assignment logic
- Auto invoice & OTP verification flows
How I work
- Clear communication always
- Deliver with proper documentation & README
- Build reusable modules to ship faster
- Open to long-term retainer or project basis
- Fast response, reliable delivery
