FinTech Microservices QA Engineer/SDET Needed

@Herculesz

Hi I can support your FinTech microservices platform as a Senior QA Engineer/SDET with strong experience in REST API testing, automation, integration testing, and performance validation. The main technical challenge is ensuring payment-critical Spring Boot microservices behave correctly across APIs, databases, caches, queues, and event-driven flows without regression risk. My approach would combine structured test planning with API validation using Postman, Swagger/OpenAPI, JSON schema checks, and automated suites using Selenium, Cucumber, JUnit/TestNG, and API automation frameworks. I can validate PostgreSQL data, Redis caching behavior, RabbitMQ/Kafka message flows, and service-to-service integration scenarios across Docker-based environments. For performance, I can design JMeter load and stress tests, analyze bottlenecks, and report latency, throughput, error rates, and scalability risks. I also understand FinTech QA concerns such as payments workflows, ISO 8583 concepts, auditability, PCI DSS awareness, defect tracking, CI/CD test execution, and Agile release support. This gives your team reliable QA coverage that protects core payment functionality while improving automation, reporting, and release confidence. Thanks, Hercules

Hi, I’m interested in supporting your FinTech microservices platform as a QA Engineer / SDET. While my primary background is software engineering, I have extensive experience testing and troubleshooting API-driven systems, microservices architectures, Docker-based environments, PostgreSQL databases, Kafka messaging workflows, and distributed applications. I regularly work with REST APIs, JSON validation, Postman, integration testing, performance analysis, logging, and production issue investigation. I have experience validating backend services, reproducing defects, reviewing API contracts, testing event-driven workflows, analyzing database consistency, and collaborating closely with engineering teams in Agile environments. I am also comfortable working with GitHub workflows, CI/CD pipelines, Docker deployments, and test automation frameworks. Availability: Immediate P.S. My engineering background helps me trace issues across APIs, databases, message queues, and infrastructure layers rather than treating testing as a purely UI-focused activity.

@FizzaNadeemK

Hi, A payments platform cannot afford hidden failures between services, so the key challenge is validating every transaction path before it reaches customers. Your focus on Kafka and RabbitMQ message flows stood out because event-driven failures often appear outside normal API checks, and I have experience building automated workflows where reliable data movement was critical. I will map the critical flows, review API and integration points, and help create structured validation coverage for releases while keeping communication clear with the development team. Before we start, which payment flows or transaction scenarios currently create the most risk and need the deepest validation first? Best Regards, Fizza Nadeem K
