SCROLL THE PLATFORM

91crew · data platform

Connect your data

We design and ship operable platforms — sources into Iceberg, catalog lineage, SQL and Spark, curated outputs. Scroll through the landscape.

02 · store & understand

Lakehouse + catalog

Data lands in Apache Iceberg. Above it, the catalog maps schemas and lineage — metadata relationships, not another data hose.

03 · transform

SQL and Spark, distinctly

Workloads pull from the lakehouse and emit curated sets. SQL and distributed compute stay visually separate paths.

04 · deliver

Trusted analytical data

Gold-layer tables and analytical surfaces — the outcome of a coherent pipeline, not a pile of exports.

05 · coordinate

One control plane

Keep scrolling for services, how we work, FAQ, and how to reach the crew.

Why work with a crew

You get practitioners who own architecture and delivery together — from the first catalog table to production syncs — not a slide-deck shop.

91crew is a practitioner crew for modern data platforms: Iceberg-first layouts, engine-agnostic catalogs, and delivery you can run after we leave.

01 · SHIP

Ship the platform

Scoped builds: ingestion, table formats, catalog, compute wiring, and the runbooks your team can keep.

02 · OPEN

Open where it matters

Iceberg-first layouts, engine-agnostic catalogs, and escape hatches so you are not locked into one vendor story.

03 · NEXT

Product on the horizon

Consulting funds the craft. An open catalog / platform product is on the waitlist — same crew, same standards.

Iceberg-first REST catalogs Spark / Trino Cutover-ready

Services

91crew offers data engineering delivery, lakehouse modernization, catalog foundations, and migration hardening for mid-market and product-led data teams.

High-intent work we take on for mid-market and product-led data teams.

PKT · PIPE

Data engineering delivery

Pipelines, quality gates, and platform ops — from greenfield to rescue missions on fragile estates.

PKT · LAKE

Lakehouse & warehouse modernization

Migrate toward open table formats, cut duplicate storage, and make analytics engines share one source of truth.

PKT · META

Catalog foundations

REST catalogs, governance hooks, and Spark / Trino wiring so tables are discoverable and safe to change.

PKT · HARD

Migration & hardening

Cutover plans, backfills, and reliability work so the new path is quieter than the old one.

How engagements run

A five-stage loop: Discover → Define → Build → Harden → Hand off — from clarity on sources to software your team can operate.

A short loop from clarity to running software.

  1. Discover

    Sources, pain, constraints, and what “done” means.

  2. Define

    Architecture sketch, milestones, and success checks.

  3. Build

    Catalog, tables, pipelines, and the interfaces teams use.

  4. Harden

    Observability, ownership, and cutover without drama.

  5. Hand off

    Docs, runbooks, and optional retainers for evolution.
