As a seasoned professional in the IT industry, my experience aligns perfectly with the demands of your project. Having worked extensively with Java for over 9 years, I possess a strong command on its various frameworks, such as Spring Boot and knowledge of Microservices Architecture. This familiarity extends to Apache Kafka and troubleshooting production errors quickly. Given that your specific project operations depend on Calypso and OPICS, I'm glad to mention that I have prior experience working with these systems, which would prove highly valuable in providing efficient job support. Moreover, I've handled complex projects involving monitoring and observability, like Grafana, Dynatrace, and Splunk - the skills required by your project extensively. My troubleshooting abilities coupled with expertise in tools to usher monitoring have yielded successful outcomes in past projects similar to yours. Lastly, being an independent freelancer rather than a company stance strengthens my commitment to personal attention and clarity in communication throughout our long-term engagement. With immediate availability as an added advantage, I'm eager to channelize my deep understanding of backend Java development with your project's needs. Let's join hands to turn your project idea into reality together!

Your consultant will hit production issues they can't debug alone - especially around Kafka message lag, Calypso trade processing failures, or microservice timeouts that Dynatrace flags but doesn't explain. Without senior-level troubleshooting, downtime costs compound fast in trading systems. Before I commit to daily support, I need clarity on two things: What's your current incident response time when a Calypso trade fails validation? And are you running Kafka in a multi-broker setup or single-node (this changes how I'd diagnose message delivery failures)? Here's how I'd structure the support: - JAVA + SPRING BOOT: Debug memory leaks using heap dumps, optimize thread pools in production configs, and fix race conditions in async processing that cause intermittent failures. - KAFKA: Troubleshoot consumer lag by analyzing partition rebalancing, implement dead letter queues for poison messages, and tune producer configs to prevent message loss during network hiccups. - CALYPSO/OPICS: Trace trade lifecycle issues through logs, identify SQL bottlenecks in MySQL queries that slow down settlement processing, and validate data mappings between systems. - DYNATRACE + SPLUNK: Set up custom dashboards to catch anomalies before they escalate, correlate distributed traces across microservices to pinpoint root causes in under 10 minutes. I've supported 4 fintech platforms where a single hour of downtime cost $50K+ in missed trades. I don't just fix symptoms - I'll document recurring patterns and suggest architectural improvements to reduce your support burden over time. Let's do a 30-minute technical screening where I walk through a recent production incident you faced and show you how I'd have resolved it.
