Description

I help companies design and scale robust backend systems, leveraging over 10 years of experience with Scala, JVM technologies, and distributed architectures. I specialize in building data-intensive applications, real-time analytics platforms, and cloud-native services on GCP and Kubernetes.

As a team lead and a hands-on developer, I’ve delivered mission-critical features for global-scale platforms — from customer-facing realtime analytics to a backup system for Kafka topics using the Parquet format, Google Cloud Storage, and BigQuery. My experience spans working with Kafka, ClickHouse, Cassandra, RocksDB, Lucene, Temporal, gRPC, protobuf, gitlab and more.

My added value:

- Proven leadership (managed & mentored 10+ engineers)

- Strong in system design and architecture

- Hands-on with large-scale environments (100+ microservices)

- Deep knowledge of event-driven systems and observability

- Sharp focus on reliability, performance, and clean code

Let’s work together if you need a backend expert who codes, leads, and delivers.
