Core Capabilities

Data Warehousing Practice

From Snowflake data lakehouses to dbt SQL transformations, Kafka streaming, and FinOps cost optimization.

Snowflake & Databricks

Cloud Data Lakehouse Architecture

Combine the low cost of cloud data lakes with the ACID transaction power of enterprise data warehouses. We design Snowflake, BigQuery, and Databricks architectures built for petabyte scale.

DWH Execution Lifecycle

How We Build Data Warehouses

A structured 6-stage delivery lifecycle from data auditing to dbt modeling, checksum validation, and FinOps cost tuning.

01

Data Source Audit & Business Requirements

We inspect existing transactional databases, SaaS APIs, file logs, and define target data schemas.

02

Lakehouse & Dimensional Model Design

Design Snowflake / Databricks data lakehouses using Kimball Star Schema dimensional modeling.

03

Fivetran & dbt Pipeline Engineering

Configure automated ingestion connectors and dbt transformation models with version-controlled SQL.

04

Security, RBAC, & PII Masking Setup

Implement role-based access control, dynamic column data masking, and automated data quality checks.

05

Data Migration & Checksum Validation

Migrate historical data, verifying checksum accuracy between legacy databases and the cloud lakehouse.

06

FinOps Cost Tuning & 24/7 SLA Support

Establish auto-suspend warehouse policies, executive BI connectivity, and 24/7 pipeline monitoring.

Client Advisory & FAQs

Data Warehousing FAQ

Answers to common questions regarding Lakehouses, dbt transformations, and cloud billing controls.

A Data Warehouse stores structured SQL data optimized for BI reporting. A Data Lake stores raw un-structured files (JSON, CSV, logs). A Data Lakehouse (Snowflake / Databricks) combines both, allowing you to query raw files with fast SQL data warehouse performance and low storage costs.
