What we do

  • Backend Systems Engineering

    Production-grade services in Go, Python and Kotlin. API design, performance work and operability built in from day one — systems designed to be run, observed and evolved, not just demoed.

  • Distributed Workflows & Orchestration

    Durable execution platforms built on Temporal, and event-driven architectures that keep long-running business processes correct through retries, failures and deploys.

  • Data Pipelines & Integration

    ETL and realtime streaming with Kinesis, serverless Go, data enrichment and warehousing into BigQuery. Making disparate systems speak one language.

  • Legacy Modernisation & Rescue

    Taking over, stabilising and evolving inherited backends. Two decades of production experience across PHP, Python, Java and Go — very little surprises us.
