You’re hiring for Java-Spring + Angular for long-term product development at Optum, with microservices, Kafka, and strong CI/CD on Docker/GitHub/Kubernetes. I’m comfortable owning end-to-end backend (Java OOP, Spring Boot/Framework, REST integration) and frontend (Angular latest, components/modules/services, routing, forms, DI, lifecycle, RxJS/Observables). I’ll also tackle CI/CD and release reliability (Docker images, GitHub workflow automation, Kubernetes deploy patterns) and help guide the migration path from Azure to Databricks while keeping service contracts stable and data flows traceable. To make this successful quickly, I’ll align on event-driven boundaries and API contracts so Kafka topics/partitions and Angular-to-REST interactions remain consistent under evolving requirements. Where should the 'Thoughtfully and Fiercely: Which Kafka-driven microservice boundaries (topics/partitions) and REST contract strategy should be prioritized first during the Azure → Databricks migration to minimize breaking changes?' be inserted, specific service, module, or migration stage?

@jaroslavcaprata

You’re looking for a full-stack engineer who can contribute to a long-term product development environment with a strong focus on Java/Spring Boot backend services and modern Angular applications. The key challenge is building reliable microservices that integrate cleanly while maintaining performance, test coverage, and code quality. I can work across Spring Boot and Angular stacks, developing RESTful APIs, microservices, Kafka-based communication flows, and MongoDB-backed services while following clean architecture practices. On the frontend, I can build reusable Angular components, manage state and asynchronous workflows with RxJS, integrate APIs, and ensure responsive, maintainable UI development. For backend reliability, I focus on proper exception handling, logging, unit testing with frameworks like JUnit/Mockito, and containerized deployment practices using Docker where required. I’m comfortable working with existing enterprise codebases and collaborating within structured product teams. One question: could you share the current project architecture—are the services already running in a Kubernetes environment, and what Angular version is the frontend currently using?

@kishanbwts

I’ve worked on several long-term projects building microservices with Spring Boot and Java, where reliable REST APIs and Kafka stream processing were critical. In one case, I helped a healthcare client like yours optimize Kafka consumer patterns to improve message throughput without data loss. For the Angular front end, I regularly build reusable components and services that integrate tightly with REST APIs. I’m comfortable managing complex state with RxJS Observables, ensuring smooth async data flows and responsive UI updates. Can you share if you have existing Kafka topics and schemas set up, or will I be designing those from scratch? Also, do you follow a standard Angular architecture or prefer a customized module setup? This kind of combined backend and frontend work is straightforward when focusing on stable API contracts and modular Angular code. I’m ready to jump in and contribute to your Optum product’s long-term success right away.
