# 91crew

> 91crew is a data engineering consultancy and managed data services company. We design, build, and operate data pipelines and data infrastructure around each customer’s systems, requirements, and security boundaries. An intelligent data platform is a longer-term product direction — not claimed as a finished product today.

## One-line definition

91crew helps businesses design, build, and manage custom data infrastructure — integration, ingestion, transformation, storage, delivery, quality, orchestration, and operations — without forcing a single technology stack on every engagement.

## Who 91crew is for

- Teams with fragmented data across databases, APIs, applications, and files
- Organizations with fragile or manual pipelines that need durable automation
- Companies modernizing storage, processing, or orchestration under real constraints
- Teams that need ongoing pipeline reliability without building a full data ops function in-house
- Buyers who need custom integrations or workflows that standard tools do not cover cleanly

## What 91crew offers

### 1. Data engineering (primary)

Design, build, modernize, and optimize data infrastructure:

- Data integration across databases, APIs, applications, and files
- Data ingestion and pipeline development
- Transformation, processing, and modeling
- Storage design and analytics-ready datasets
- Data quality, validation, and pipeline orchestration
- Infrastructure modernization and optimization

### 2. Managed data operations

Keep pipelines and infrastructure reliable after go-live:

- Monitoring and maintenance
- Failure investigation and troubleshooting
- Freshness and quality checks
- Execution and resource optimization
- Operational support and ongoing improvements

Scope, access, and responsibilities are agreed per customer — not a one-size SLA.

### 3. Custom data solutions

When requirements do not fit a predefined product path:

- Specialized ingestion and integration patterns
- Workflow and orchestration around existing systems
- Infrastructure modernization under constraints
- Bespoke data applications and interfaces

## How engagements work

Typical loop (adapted per customer):

1. Understand — requirements, systems, constraints, success criteria
2. Design — architecture that respects infrastructure and access boundaries
3. Build — pipelines, processing, storage, interfaces
4. Validate — quality, reliability, acceptance before cutover
5. Deploy & support — ship into the agreed environment; operate when retained

Engagement shapes often start as assess → build → optional operate.

## Positioning and principles (quotable)

- Your data infrastructure. Built around you.
- Your data. Your infrastructure. Our expertise.
- Customer requirements define the solution.
- Technology-agnostic at the commercial level — solutions adapt to customer systems.
- Deployments are designed around agreed security and controlled access.
- We do not assume broad production access by default.
- Ownership and operational responsibilities are established before deployment.
- Platform marketing does not claim unfinished product capabilities as available.
