Senior Java Developer for Travel Booking Project

@ykarora26

With a strong background in Java 8/17 and Spring Boot, I have successfully developed microservices and utilized Apache Kafka for efficient pub/sub communication. I am keen to understand your Travel Booking Management project's architecture and contribute effectively. Could you provide more insights into the specific orchestration patterns and challenges involved in the workflows? Regards, Yogesh Kumar

Hi, Your Travel Booking platform runs on Spring Boot microservices with Kafka pub/sub, and you need someone who can read the service map fast and start contributing on the event flows, not spend a week getting oriented. That is where I fit. I have worked with Java for four years, building backends and REST APIs, and I am comfortable tracing service-to-service calls and orchestration paths across a distributed system. Kafka topics, producers/consumers, and event-driven handoffs between booking, payment, and inventory services are the kind of workflow I like untangling. For a part-time role at 2-3 hours a day I can commit to steady daily output and flexible hours. First step: point me to the repo or an architecture doc for one service, and I will map its Kafka events and return a short plan for my first task. Which service should I pick up first? Regards, Nurullah Al Masum

Hi, I'm interested in this opportunity. I have nearly 9 years of experience building Java backend systems, primarily in the BFSI domain, where I've worked extensively with Java 8/17, Spring Boot, microservices, REST/SOAP APIs, PostgreSQL, distributed systems, and production-grade integrations. Some relevant experience includes: * Migrating monolithic/bounded JAR applications to microservices. * Designing and developing backend services for enterprise banking platforms serving over 1 million customers. * Building and maintaining event-driven integrations between multiple enterprise systems. * Leading architecture discussions, production deployments, and resolving critical production issues under strict SLAs. * Working on scalable backend services, observability improvements, Elasticsearch/OpenSearch migrations, and security remediation (VAPT). While my primary domain is BFSI rather than travel booking, I'm experienced in understanding complex business workflows, distributed architectures, and integrating multiple services. I'm confident I can ramp up quickly on the travel domain and contribute effectively. I'm based in Bengaluru and can commit 2–3 hours per day with flexible timings. Happy to share my profile and discuss how I can contribute to the project. Thanks, Mohanraj Selvam

@olejka1

Hello! My experience in Java development with Spring Boot, microservices, and event-driven architecture fully matches your requirements. I have worked with Kafka and Pub/Sub patterns for inter-service communication and orchestration in distributed systems. I also have practical experience in the travel domain. I can quickly understand complex multi-service architectures and contribute effectively from day one. To clarify the scope and estimate the cost, could you please answer a few questions: 1) How many microservices are currently in the system? 2) How is orchestration between services structured? 3) What is the expected message volume through Kafka (peak and average)? 4) Are there any specific performance requirements? 5) What is the timeline for the first deliverable? I am available to work 2-3 hours a day in the evening (UTC+03:00) and can start immediately. I look forward to discussing the details.
