Kafka and microservices job support for distributed Java systems

Events arrive twice, out of order or not at all, and the bug spans four services. A senior engineer who has built Kafka consumers, resilient third-party integrations and distributed transactions joins you over screen-share and traces it with you.

What we cover

What Kafka & microservices covers

Apache Kafka

Consumer groups, partition-aware scaling, offset management, ordering guarantees and dead-letter handling.

  • Kafka
  • Consumer groups
  • Partitions
  • Offsets
  • Dead-letter topics

Microservice frameworks

Spring Boot, Spring Cloud, Quarkus and Dropwizard services with clean REST and gRPC APIs — and splitting monoliths without breaking callers.

  • Spring Cloud
  • Quarkus
  • Dropwizard
  • REST
  • gRPC

Resilience and correctness

Idempotency keys, deduplication, timeouts, retries with jitter, circuit breakers, fallbacks and state-machine validation.

  • Idempotency
  • Circuit breakers
  • Retries
  • Sagas
  • Distributed transactions

Integration and data

Apache Camel and JAX-RS integration routes, and the databases behind your services.

  • Apache Camel
  • JAX-RS
  • PostgreSQL
  • MySQL
  • Oracle
  • MarkLogic
  • Elasticsearch
Sound familiar?

Where developers usually get stuck

  • A consumer group rebalances constantly and processing stalls.
  • The same event is processed twice and creates duplicate records.
  • A flaky third-party API takes your service down every time it has an outage.
  • You need to carve a service out of the monolith without breaking existing callers.
  • A multi-service update leaves data half-written when one step fails.

Client stories

What developers say after working with us

Names are shortened to protect our clients’ confidentiality.

“The technical mentoring helped me work through complex Java, Spring Boot, and microservices challenges. The explanations were practical and focused on real-world development, debugging, and production troubleshooting.”

Michael A.USA · Java & microservices support

“I needed guidance with Camunda process orchestration, BPMN workflows, external task workers, and Java integration. The structured technical sessions helped me understand workflow implementation and resolve development challenges.”

Daniel F.Germany · Camunda BPM support

“The support covered React, Java, Spring Boot, REST APIs, and database integration. The practical approach helped me understand how frontend and backend components work together in an enterprise application.”

Omar H.Dubai, UAE · Full stack development

“The support covered React, Java, Spring Boot, API integration, and database operations. I especially appreciated the step-by-step explanations and practical examples that helped me troubleshoot full-stack application issues.”

Priya M.Full stack development support

“The sessions focused on Java microservices, exception handling, SQL queries, logs, and debugging production issues. The guidance was structured and focused on understanding the root cause instead of just fixing the immediate problem.”

Vikram P.Java microservices & production support

“I needed guidance across multiple technologies, including Java, Camunda, React, and REST APIs. The integrated approach helped me connect backend workflows with frontend functionality and build a better understanding of the complete application.”

How we work

Ground rules that protect you and your job

You stay at the keyboard

You share your screen and do the work; we guide, explain and review. You own your commits — that’s how the skills stick.

Your employer’s systems stay protected

We never ask for passwords or repository access. Please check your employer’s policies allow screen-sharing before you book. We don’t take on export-controlled (ITAR/EAR), classified or health-records work.

Confidential by default

We sign an NDA on request and never share who our clients are or where they work.

One engineer, one context

You won’t have to re-explain your project each time. Your engineer keeps notes on your codebase and goals.

How it works

From first call to confident on your own

  1. Free scoping call

    30 minutes on your role, stack, team rhythm and where you feel shaky. Share your requirement and we match you with an engineer who knows your stack.

  2. Schedule around your stand-up

    Sessions land in your local working hours — Americas, Europe, Middle East or Asia-Pacific — with a slot before stand-up if you want one.

  3. Work through your tickets together

    You share your screen and drive. We explain the code, debug with you, and review your changes before you open the PR.

  4. Taper off as you grow

    Most engineers move from daily to weekly sessions within a couple of months. The goal is that you no longer need us.

FAQ

Kafka & microservices: common questions

Can’t find your answer? Email contact@jobsupport4u.com.

Do you support Quarkus and Dropwizard, or only Spring Boot?

All of them — Spring Boot, Spring Cloud, Quarkus and Dropwizard — with REST, gRPC or JAX-RS APIs.

Can you help break up a monolith?

Yes. We help identify service boundaries, introduce Kafka or REST/gRPC communication, and keep existing callers working during the move.

Which databases do you work with?

PostgreSQL, MySQL, Oracle, MarkLogic and Elasticsearch, usually through Hibernate/JPA or plain SQL.
