Hi there My approach Spring Boot Backend — Develop clean, maintainable services and REST APIs for users, destinations, trips, bookings, and other required travel workflows. Microservices Architecture — Structure services appropriately for scalability, maintainability, and independent deployment where microservices are required. Travel API Integrations — Integrate external APIs for hotels, flights, activities, maps, availability, pricing, or other required services. Database & Data Layer — Design and optimize the required database entities, relationships, queries, and transaction handling. Authentication & Security — Implement secure authentication, authorization, API validation, and appropriate protection for sensitive data. Booking & Payment Workflows — Handle booking lifecycle, availability, confirmations, cancellations, and payment integration where required. Testing & Documentation — Provide API testing, error handling, logging, and clear API documentation for frontend/mobile integration. Quick questions 1. Is this a new Spring Boot backend or an existing project? 2. Which database and Spring Boot/Java versions are currently being used? 3. Which travel APIs need to be integrated? 4. Do you already have the frontend/mobile application consuming these APIs? 5. Is the project already structured as microservices, or should the architecture be designed from scratch? Thanks

@sharonl39

? Hi! Your travel booking microservices setup sounds like a genuinely interesting project to work on. My background is 6-10 years as a Full Stack Engineer, mostly Python/Django/Flask, with hands-on experience in event-driven architecture, service-to-service communication, and REST API design — the same core patterns your Kafka/Pub-Sub setup relies on, just in a different language. I pick up new stacks fast when the underlying architecture is familiar. I know the post specifies Java/Spring Boot specifically, so I want to be upfront: that's not my primary stack. If you're open to a strong backend generalist who can ramp up on Java quickly, I'd love to chat. If Java experience is non-negotiable, no worries at all — just wanted to raise my hand. Would you be open to a quick call to see if this could work?

@cangkangk

Hi there! Your travel booking platform's real challenge isn't just building services — it's making them talk to each other reliably under complex, event-driven workflows like booking, cancellation, and payment orchestration. I bring hands-on experience designing Spring Boot microservices with Kafka-based pub/sub, ensuring reliable service-to-service communication without message loss or duplicate processing. For orchestration-heavy systems like reservations, I focus on idempotent event handling and clear saga/choreography patterns so partial failures don't corrupt booking states. Having worked on reservation and inventory-style systems before, I can quickly map your existing architecture and contribute without a long ramp-up period. My approach: first audit current service boundaries and Kafka topic design, then optimize inter-service contracts and error handling, followed by continuous support during active development sprints. I'm comfortable with the part-time, 2-3 hours/day structure and flexible hours you've outlined. Happy to share my availability and discuss the architecture in more detail. Best regards
