What we run

Six instruments, one vessel

Each practice ships on its own, or as part of a longer voyage — most clients start with one and pull in the rest as the map fills in.

01

Data Engineering

Most data platforms don't fail loudly — they fail quietly, one broken job and one manual patch at a time, until nobody trusts the numbers. We rebuild the plumbing: idempotent ingestion, tested transformations, and orchestration your own engineers can read a year from now without a handoff call to us.

  • Batch and streaming ingestion from source systems
  • Warehouse and lakehouse architecture on your cloud of choice
  • Orchestration, testing, and CI/CD for every pipeline we touch
  • Cost and performance tuning for workloads already in production
02

Analytics & BI

A dashboard nobody opens is a maintenance cost with no return. We start from the decision, not the data model: what does the finance lead do differently on Monday morning, and what's the smallest report that changes that. Everything else is cut.

  • Semantic and metrics layers with one definition of truth
  • Executive, operational, and self-serve dashboard tiers
  • Power BI, Tableau, and Looker implementation and migration
  • Adoption support — training the people who'll actually use it
03

Applied AI

We scope AI work the way we'd scope any engineering project: a named task, a measurable baseline, and a rollback plan. That discipline is why the models we ship tend to still be running a year later, instead of quietly retired after the pilot.

  • Use-case scoping and feasibility assessment before any build
  • RAG, agentic, and classical ML systems grounded in your own data
  • Evaluation harnesses that measure against your current baseline
  • Production monitoring, guardrails, and cost controls
04

Data Governance

Governance that lives in a slide deck doesn't survive contact with a real audit. We encode ownership, access, and quality rules directly into the platform, so the answer to "who can see this and why" is a query, not a meeting.

  • Column and table-level lineage across the full estate
  • Role-based access control mapped to real business ownership
  • Automated data-quality checks with alerting, not spreadsheets
  • Documentation that stays in sync because it's generated, not written
05

Data Science

A model that lives in a notebook hasn't shipped. We pair the statistical work with the plumbing to put it in front of the person who has to act on it — a forecast in the planning tool, a segment in the campaign platform, a test result in the roadmap review.

  • Demand forecasting and inventory optimization
  • Customer segmentation and lifetime-value modelling
  • A/B testing infrastructure and experiment design
  • Statistical review of existing models before you scale them
06

Team Enablement

Every engagement ends with a handoff, and we treat that handoff as a deliverable in its own right — documentation, recorded walkthroughs, and paired sessions until your team can extend the platform without calling us first.

  • Paired engineering sessions during the build, not just after
  • Runbooks and architecture docs written for your next hire
  • Workshops on the specific tools and patterns we implemented
  • A defined off-ramp — no dependency on us to keep the lights on

Not sure which instrument you need?

Most engagements start with a short scoping call, not a signed statement of work.
