You will get Full-Stack Java Spring Boot + React/Next.js Web App Development
Project details
Senior Software Engineer delivering fast, secure web apps with Java Spring Boot, MySQL, React, and Next.js. I design clean REST APIs and modern UIs, then ship production-ready builds on AWS with Docker and CI/CD. What you get: clear architecture, authentication/authorization (JWT/OAuth), validation and error handling, logging/metrics, MySQL schema with migrations (Flyway), and responsive, accessible, SEO-friendly UI. I integrate Stripe/payments, email/SMS/WhatsApp, and third-party APIs. You receive source code, README, env samples, and a handover call. Process: scope → DB/API design → UI build → QA/tests → deploy. Tiers: Starter = backend API (up to 3 endpoints) + DB + Docker. Standard = full-stack MVP (5 pages) with auth + CRUD + MySQL. Advanced = production build (8 pages), microservices or modular monolith, CI/CD, AWS deploy and performance tuning. Tech: Java 17+, Spring Boot 3, Spring Security, JPA/Hibernate, MySQL 8, React 18, Next.js, TypeScript, Tailwind, Axios, Jest, Docker, GitHub Actions, AWS.
