You will get a custom SaaS web application built with React and Spring Boot
Project details
You will get a production-ready SaaS web application built with a modern, scalable stack: Spring Boot (Java 21) backend, React + TypeScript frontend and AWS cloud infrastructure.
I am a software engineer and senior QA specialist with 7+ years of experience. I run my own software company where I have designed, built and operated multiple live SaaS products — including a multi-tenant email marketing platform, a language learning app with AI features, and business management tools used by real paying customers. See the attached case study for a detailed example.
What makes me different: most developers write code — I also test it professionally. Quality assurance is my day job in fintech, so your application will be verified end-to-end (functionality, edge cases, security basics, mobile responsiveness) before delivery, not after users find the bugs.
What's included:
• Clean architecture with database migrations
• Secure authentication and role-based access
• Admin dashboard and analytics
• Integrations: payments, email delivery, AI (OpenAI/Claude), messaging APIs
• AWS deployment with SSL, domain setup and full handover
Let's turn your idea into a working product.

About Hasan Huseyin Ali
Senior QA Engineer & Full-Stack Developer
Kartal, Turkey - 1:48 am local time
On the mobile side, I develop cross-platform apps using React Native, Flutter, and Expo, and I manage the full app publishing lifecycle — including App Store and Google Play submissions, release management, and version control workflows.
For real-time features, I integrate WebRTC, WebSocket, and Socket.ıo to build live communication, streaming, and chat functionalities. I deploy and manage cloud infrastructure on AWS, handling services like EC2, S3, Lambda, and RDS.
What I bring to your project:
End-to-end development: UI → API → Database → Cloud
Real-time & live communication systems
Cross-platform mobile apps with native-quality UX
Production-ready deployments with CI/CD pipelines
Clean, maintainable code with solid architecture
Whether you need a web app, mobile app, or a full-stack product — I can take it from idea to live deployment.

Requirements & technical planning
We define the feature scope, user roles and data model together. I prepare a clear technical plan and screen list so we both know exactly what will be built.
UI design & architecture setup
I design the interface layout and set up the project architecture: backend API, database schema with migrations, and frontend structure.
