stage 01 — ingest
● ingest
Data Engineering
We design and build the pipelines that move data from wherever it's born to wherever it needs to work: batch ETL/ELT, streaming ingestion, change-data-capture, and event pipelines. Built in Python, orchestrated, retried, and alerting before they ever touch production.
- Batch & streaming pipelines (Airflow, Kafka, Spark)
- API, file, and database ingestion frameworks
- Data quality checks built into every run
stage 02 — migrate
● migrate
Data Migration
Legacy database to cloud warehouse. On-prem to lakehouse. One vendor to another. We map schemas, reconcile every row, and cut over with a rollback plan — so migration day is uneventful, which is exactly the goal.
- Schema mapping & lineage documentation
- Zero/low-downtime cutover strategies
- Row-level reconciliation & audit trails
stage 03 — model
● warehouse
Data Warehousing
Modern warehouse architecture on Snowflake, BigQuery, or Redshift — dimensional models or wide tables, whichever your access patterns actually need. Layered raw → staged → curated, with dbt managing every transformation as version-controlled SQL.
- dbt-based transformation layers
- Star schema & medallion architecture design
- Cost & query performance tuning
stage 04 — analyze
● transform
Data Analytics
Curated data is only useful if someone trusts it enough to decide with it. We build the metrics layer, define the business logic once, and hand off models that answer real questions — not just dashboards that look busy.
- Metrics layer & semantic modeling
- Statistical & cohort analysis in Python
- Self-serve analytics enablement
stage 05 — visualize
● deploy
Data Visualization
Dashboards built for the decision someone actually has to make, not for a screenshot. We design the view, wire it to the warehouse, and ship it in Looker, Power BI, Tableau, or a custom Python app when the off-the-shelf tool can't keep up.
- Executive & operational dashboards
- Looker / Power BI / Tableau implementation
- Custom visualization apps (Plotly, D3, Streamlit)
underneath all five
● ci/cd
Engineering Discipline
Every pipeline above is built the same way: Python codebase, Git version control, peer-reviewed pull requests, and CI/CD that tests and deploys changes automatically. Infrastructure as code. No untracked changes in production, ever.
- Git-based branching & review workflows
- CI/CD with automated testing & rollback
- Infrastructure as code (Terraform)
