Apache Kafka Engineers in Europe — Real-Time Data & Streaming Platforms

European Apache Kafka Engineers for Real-Time Data Systems

Designing, scaling, and managing event-driven architectures and high-throughput streaming pipelines across Europe.

H-Studio — a European team of architects and senior engineers who design and develop real-time data platforms on Apache Kafka for companies across Europe.

We build reliable, high-load, and fully event-driven systems for fintech, SaaS, e-commerce, analytics, telecommunications, and enterprise products where low latency, high message delivery speed, and stability under load are critical.

If your company needs Kafka engineers, real-time architecture, streaming pipelines, or refactoring of an existing event system — we do this at an enterprise level.

What We Build (Kafka Expertise)

1. Kafka-Based Real-Time Data Pipelines

Systems processing events:

  • •millions of messages per second
  • •real-time ingestion
  • •consistent delivery
  • •fault-tolerant load distribution

Технологии: Kafka, Kafka Streams, KRaft, Schema Registry, Connect, Debezium, Flink

2. Event-Driven Microservices

We create architecture where every part of the system reacts to events:

  • •asynchronous processing
  • •horizontal scaling
  • •independent services
  • •low latency

Паттерны: Event Sourcing, CQRS, Saga, Outbox Pattern, Stream Processing

3. High-Load Messaging Systems

We build message delivery and processing systems that handle:

  • •billions of events/day
  • •guaranteed delivery
  • •load distribution across partitions
  • •minimal response time

Stack: Kafka Streams, Spring Boot, Kotlin, Java 20, gRPC

4. Migrating Legacy Systems to Kafka

We migrate old architectures:

  • •from RabbitMQ
  • •from cron-based batch systems
  • •from monoliths with synchronous APIs
  • •from outdated ETL

Results:

  • •10–100× processing acceleration
  • •reliable delivery
  • •reduced database load
  • •predictable architecture

5. Real-Time Analytics Engines

We create analytical cores:

  • •clickstream processing
  • •fraud detection
  • •event scoring
  • •real-time metrics
  • •ML-trigger pipelines

Чаще всего с: ClickHouse, Kafka, dbt, Airbyte, Flink, Grafana

6. Kafka Infra & DevOps Support

We create and maintain:

  • •production Kafka clusters
  • •monitoring & alerting pipelines
  • •disaster recovery
  • •HA replication
  • •zero-downtime updates

Инструменты: Kubernetes, Terraform, Helm, Prometheus, Grafana

FAQ — Apache Kafka Engineering in Europe

Do you build Kafka architecture from scratch?

Yes, we design full-stack event-driven systems: from topics to stream-processing and microservices.

Can you migrate our existing system to Kafka?

Yes. We migrate from RabbitMQ, batch-ETL, monoliths, and API-dependent architectures.

Can you design for millions of events per second?

Yes. We have experience building systems with 5M–15M msgs/sec.

Do you offer long-term support?

Yes. 24/7 SLA, monitoring, disaster recovery.

Can you work with fintech or regulated industries?

Yes. We have experience working with strictly regulated sectors (fintech, banks, government).
