Java Spring Boot Microservices Developer

@kamran2012

Hello there, I will deliver production-ready Spring Boot microservices — event-driven publishing/consumption, MySQL persistence with Flyway migrations per service, and an S3 integration module with upload/download demo endpoints — all containerized via Docker Compose for one-command local startup. For the event broker layer, I will design each service with an outbox pattern so events are persisted atomically alongside domain data before publishing. This prevents silent event loss during broker outages and makes the entire flow auditable — which also simplifies your integration testing for the "no data loss" requirement. Questions: 1) Which event broker are you using internally — Kafka, RabbitMQ, or something else? Looking forward to your response. Best regards, Kamran

Drawing upon my background as a Senior Java Developer, I have assessed the project requirements—from the product specifications to the infrastructure needs across Dev, UAT, and Prod environments. My proposed approach prioritizes industry-standard best practices, ensuring a highly secure, stable, and distributed service architecture that aligns with your specific technical standards. Given the project’s complexity and the performance requirements, I estimate a delivery window of 30 to 75 days.

@Shrutibimpl

Hello There, As per my understanding you want a production grade event driven microservices architecture built on Spring Boot with MySQL persistence and AWS S3 integration. 1) Which message broker like RabbitMQ or Kafka do you prefer for your event communication? 2) Do you have specific S3 bucket policies or encryption requirements for the user uploads? 3) Which migration tool like Flyway or Liquibase should I integrate for your MySQL schema management? I will build a robust foundation for your business that grows as your user base expands. You will get a system where different parts communicate instantly without slowing each other down, ensuring a smooth experience even during peak traffic. By automating your data storage and file management, I am giving your team a reliable platform that reduces manual errors and provides total peace of mind for your operations. I will develop the services using Spring Boot and Spring Cloud Stream to ensure a fully decoupled and asynchronous event architecture. I will implement Flyway for automatic database versioning and use the AWS SDK for high performance S3 object handling with built in retry logic. The entire stack will be containerized using Docker Compose for a consistent local environment, providing you with a scalable ecosystem ready for immediate cloud deployment. Best regards, Bharat Joshi

@serviceaxisgroup

Hi, I can help with production-ready Spring Boot microservices that are fully event-driven and can be started locally end-to-end. I’ll begin by reviewing your current event broker contracts and defining clean boundaries per service, then scaffolding event publishing/consumption plus MySQL migrations. I’ll reduce risk with a small vertical slice, automated integration tests for event flow and REST latency, and a one-command docker-compose environment. Which internal broker are you using, and do you prefer Flyway or Liquibase for MySQL migrations? I’m happy to align on setup and start immediately.

@sakshigweb

Hi, Event-driven Spring Boot microservices where services are genuinely decoupled — not just loosely coupled by convention — require clean event contracts and disciplined schema boundaries from the first commit. That's the foundation I'll build on. Here's what I'll deliver: - Spring Boot microservices — each service publishing and consuming events through your broker, cleanly decoupled with well-defined event contracts and no shared database coupling - MySQL schema per service — individual schema boundaries with Flyway migration scripts so a fresh database boots and migrates cleanly every time - S3 integration module — file upload and download wired to AWS S3 with a working demo endpoint demonstrating operations with temporary credentials - Dockerfile + docker-compose — full stack boots locally from a single command, migrations run automatically on startup Code structured for high testability — services independently deployable and verifiable without full-stack dependencies at test time. We recently delivered a Java-based WordPress plugin project where clean architecture and precise delivery were the entire brief — same rigour goes into every Java build. One question: what event broker are you using internally — Kafka, RabbitMQ, or something custom? That shapes the event publishing pattern from the start.
