You will get develop microservices using java, spring boot, and rest apis
Project details
I will develop a secure and scalable Java-based backend integrated with Web3.js blockchain functionality, ideal for apps like restaurant booking, event management, fintech, or NFT platforms. This project combines powerful Spring Boot REST APIs, a responsive Ionic frontend, and blockchain integration to deliver next-generation digital solutions.
You’ll get a complete backend system with structured APIs, authentication (JWT/OAuth), database setup (MySQL/PostgreSQL), and Web3.js integration for decentralized transactions or NFT features. The solution ensures high performance, transparency, and data integrity.
My process includes understanding your requirements, designing the architecture, building APIs, integrating blockchain modules, connecting with your frontend, and deploying the final application. I also provide testing, documentation, and post-deployment support.
Whether you need a simple API setup, full backend build, or complete blockchain-enabled system, I’ll deliver production-ready code that meets your business goals — with clean structure, security, and scalability at its core.
