Hello, Drawing on my background as a Senior Java Developer, I have assessed your project requirements carefully—from the gateway’s functional expectations to the infrastructure considerations across Dev, UAT, and Production environments. I can implement a high-performance Spring Boot-based API Gateway that sits in front of your User, Order, and Payment microservices, with a strong focus on low-latency routing, distributed rate limiting, and JWT-based security. What I will deliver 1. API Gateway for 3 Microservices I will build a gateway that cleanly routes incoming traffic to: User Service Order Service Payment Service The gateway will be optimized for high concurrency (1000+ concurrent requests) and designed to forward requests efficiently with minimal overhead. 2. Distributed Redis-backed Rate Limiter To protect your APIs from abuse and ensure fair usage, I will implement a distributed rate limiter backed by Redis, throttling traffic per API key. This will ensure: consistent throttling across multiple gateway instances reliable enforcement in scaled/distributed deployments configurable request thresholds for easy tuning later 3. JWT Authentication & Authorization with Spring Security All sensitive operations will be secured using JWT tokens through Spring Security, including: user login order placement payment processing any other protected endpoints This layer will enforce both authentication and authorization, ensuring only valid and permitted requests reach downstream services. 4. Clean Controller-Service-Repository Structure Although API Gateway projects often lean toward filter-driven architecture, I understand your requirement for a familiar and maintainable Controller-Service-Repository style. I will structure the codebase so it remains: clean readable extensible easy for future feature development 5. Unit Testing I will include unit tests for the most critical areas, especially: rate limiter behavior security filters / JWT validation key gateway routing and access-control scenarios where applicable 6. README Documentation A concise setup guide will be included covering: local development setup environment configuration Redis setup and clustering tips JWT configuration overview How to adjust rate-limit thresholds Technical approach My proposed approach prioritizes industry-standard best practices, ensuring a highly secure, stable, and distributed service architecture aligned with your technical expectations. The implementation would typically include: Spring Boot 3 + Java 17 Spring Cloud Gateway for reactive, efficient routing Spring Security for JWT-based protection Redis for distributed rate limiting and shared state clear configuration for Dev / UAT / Prod clean exception handling, logging, and maintainable package structure Where needed, I can also help define: API key strategy route-level policies secure token validation flow performance-oriented configuration for high-throughput workloads Delivery estimate Given the project’s complexity, security requirements, testing scope, and infrastructure considerations, I estimate a delivery window of: 30 to 75 days The exact timeline depends on: The number of secured endpoints current microservice readiness deployment/environment complexity Redis topology and infrastructure policies whether CI/CD and integration support are also expected Why I’m a strong fit Strong experience with Java 17, Spring Boot, and microservice architecture Hands-on understanding of gateway security, JWT, Redis, and distributed systems Focus on producing clean, production-ready code Careful attention to maintainability, readability, and performance Ability to align implementation with existing enterprise environments Closing I would be glad to help you deliver a gateway that not only works correctly, but is also scalable, secure, and easy to maintain inside your current microservice ecosystem. If you’d like, I can also prepare: a shorter freelance-platform version of this proposal, a more technical version, or a more persuasive bid-style version with a stronger sales tone.

@jaroslavcaprata

Migrating legacy APIs into a cleaner Spring Boot service layer is usually less about rewriting endpoints and more about preserving behavior while improving structure, testability, and maintainability. The pairing setup you described makes sense for that kind of iterative migration work, especially when API contracts and business logic need to be validated in real time. I’m comfortable working directly in Spring Boot stacks with Spring MVC, JPA, Maven, and MySQL, including controller/service/repository separation, API versioning, validation layers, and incremental refactoring of older endpoints. During live sessions, I typically focus on keeping changes production-safe: consistent DTOs, proper exception handling, transaction boundaries, and test coverage alongside implementation rather than after the fact. I also work comfortably with Swagger/OpenAPI and JUnit so endpoint documentation and regression safety remain aligned as APIs evolve. The 8:00 pm – 2:30 am IST collaboration window works for me, and I’m comfortable with rapid development cycles where code quality and communication both matter day-to-day.
