Tharindu W.
About this gig
Is your Kafka setup lagging, losing messages, or not wired up yet? I'm a Senior Software Engineer at a fintech company who builds and runs Kafka (AWS MSK) event pipelines and Spring Boot microservices in production, and I can get yours working reliably.
What I can do:
Set up Kafka locally (Docker), on Kubernetes or on AWS MSK
Build producers and consumers in Java / Spring Boot or WebFlux
Fix consumer lag, rebalancing, and lost or duplicate messages
Add retries, dead-letter topics, idempotency and ordering guarantees
Add schema registry, monitoring and tuning
What you get: working, tested code (Standard and Premium), a short written report of what I found and changed, and clear updates as I go.
Please message me before ordering so we can confirm scope. Tell me where your Kafka runs and what's going wrong.

FAQ
Do you work with managed Kafka like AWS MSK?
Yes. I work with AWS MSK and with self-hosted clusters on Docker or Kubernetes.

Mainly Java with Spring Boot or WebFlux. Rust is available for performance-critical services.
What access do you need?
Read access to your configs or code and a test or staging environment. The health check never needs production credentials.
