How it works

From the whiteboard to production.

Every engagement follows the same three steps, so you always know where your project stands.

Whiteboard sketch of a custom platformUsers connect to a web app, which talks to an API, which reads and writes data that feeds dashboards. A checklist reads: whiteboard, diagram, code.ship insmall stepscustom platformusersweb appAPIdatadashboardswhiteboarddiagramcode
  1. 01

    Whiteboard

    Bring the messy version. We sketch the problem, the people, and the data with you, in person or on a call.

  2. 02

    Diagram

    The sketch becomes a system diagram: screens, APIs, data flows, and a phased plan with clear scope before any code.

  3. 03

    Code

    We build it full stack, from frontend and backend to data and cloud, and ship in small steps you can see and use.

What we build

Every layer of the platform, one team.

Most custom platforms need an app, the data behind it, the reporting on top, and the cloud underneath. We build all four, so nothing gets lost between vendors.

Also in the toolbox

  • Data Modeling Star schemas, dbt, semantic layers

    Clean dimensional models and dbt transformations that make analytics cheaper to run and easier to trust.

  • Pipeline Orchestration Airflow · Dagster · Prefect

    DAGs that retry, alert, and backfill themselves, with a playbook so your on-call doesn't have to guess.

  • AI & Automation Agents · LLMs · RAG

    Production AI agents on your data. Ollama, OpenAI, Claude. The right model for the right cost.

  • Governance & Security Access control · PII · SOC 2

    Row-level security, data masking, audit logs. The boring stuff that keeps you out of the news.

  • Performance Tuning Query optimization, indexing

    Dashboards that load in 300ms instead of 30 seconds, and warehouse bills cut down to size.

  • Data Quality Great Expectations · Monte Carlo

    Tests, observability, and anomaly detection so you catch bad data before the CEO does.
