Our Tech Stack

Java Applications and SDK Development: Developed in Java, our applications provide integrations with multiple marketing channel APIs, pulling and pushing data to them. Highly concurrent and efficient in their approach, they interact with significant data volumes, cheaply and quickly. Deployed as microservices on an AWS-hosted Kubernetes cluster (EKS), our architecture ensures scalability, resilience, and efficient management of workloads.

Rich Data Environment: We use Airflow as a scheduler and Data Build Tool (dbt-core) to craft efficient data pipelines with an extensively customised setup leveraging the flexibility of Python. We interact with data seamlessly using Redshift, Athena, and DuckDB. Our Redshift setup employs a decentralised structure via Data Sharing, enhancing flexibility and scalability.

Comprehensive Cloud and DevOps Integration: Our tech arsenal includes Terraform, Docker, Jenkins forming a robust foundation for cloud-based development and seamless DevOps integration.

Detailed Monitoring Capabilities: Monitoring is a top priority, and we employ ELK, Grafana, Looker, OpsGenie and internally developed technologies to ensure real-time visibility into system performance and data workflows.
