We Speak Big Data


Programming Languages

Programming skills are critical when developing big data platforms. The more you know, the easier it becomes to implement the right solution. Our programmers master languages such as Java, Scala, Go, Python, Kotlin, and C++.



As time goes by, companies collect enormous amounts of data. Our devs use the following frameworks that help them structure and prepare this data: Spring, Apache Spark, Apache Beam, Flask, and Akka.



When we talk about big volumes, wide variety, and high velocity of data, the infrastructure will “make or break” the implementation. Our team works with: Kubernetes, Docker, Terraform, Terragrunt, Ansible, Puppet, and Xen.

Databases & Storage

Databases & Storage

Our engineers also have broad experience with various technologies such as: Cassandra, BigQuery, Hive, MongoDB, Solr, Elasticsearch, OracleDB, PostgreSQL, Redis, HDFS, GCS, Amazon S3, and GlustersFs.

Processing & Pipelines

Processing & Pipelines

The volume and velocity of data have grown in recent years. So, technologies have had to adapt to the new reality. Our architects master big data tools such as Apache Spark, Kafka, Cloud Pub/Sub, MQTT, Airflow, Ozie, Apache NiFi, and Sqoop.



Our experts own the skills to ensure successful completion of big data projects, including AI / ML, Cloud, or IoT areas. We have experience working with on-premise environments, using Hadoop platform, as well as with GCP, Azure, or AWS, which puts us in a position to manage any project, regardless of its complexity.


You couldn’t build a city with a single tool. Nor could you enable your dev practice with one. Microservices, CI / CD, TDD, and Agile Scrum are four distinctive work methodologies used by our team when it comes to complex big data projects.
