02 / TechnologiesStack & architecture

Technologies we practice for data-driven transformation.

We harness technologies across Data Integration, Warehousing, Analytics, Visualisation and Reporting to leverage business data — delivering faster, informed and proactive decisions while preserving security and confidentiality.

Capability stacks

Tools we use, picked for the job.

We're tool-agnostic but opinionated. Selection is driven by use case, data gravity, latency, total cost of ownership and team operability — never by vendor preference.

How we choose

Principles over preferences.

Fit for purpose

We match the tool to the workload — latency, volume, cost, team skill — not to a vendor relationship.

Open by default

Open formats and open standards (Delta, Iceberg, Parquet, SQL) so customers are never locked in.

Governance first

Catalog, lineage, access and PII handling are designed in from day one — not bolted on later.

Operable on day 90

We design for the team that will run it — clear SLAs, observability and runbooks before handover.
