Service 02 · Data Engineering

Data pipelines that hold up, audited from source to dashboard.

Ingestion, warehousing, and transformation infrastructure built to survive contact with real operational data — versioned, tested, and documented well enough that your team can run it without us. Delivered to startups, SMBs, and enterprises across Nepal.

What the practice covers

Six capabilities, one accountable team

01

Pipeline architecture

Batch and streaming ingestion designed against your actual source systems.

02

Warehouse modeling

Dimensional models on Snowflake, BigQuery, or Postgres — built for the queries you'll actually run.

03

Transformation as code

dbt models, reviewed in pull requests, tested against data-quality assertions.

04

Orchestration

Airflow or Dagster DAGs with retries, alerting, and SLA tracking built in.

05

Data quality

Schema and freshness checks that fail loudly before bad data reaches a dashboard.

06

Governance & lineage

Column-level lineage and access controls mapped to your compliance requirements.

How an engagement runs

Four phases, each with a named deliverable

Weeks 1–2

Assess

Source-system inventory and a data model priced against the ingestion volume.

Weeks 3–5

Build

Pipelines and warehouse models stood up in your cloud account, not ours.

Weeks 6–8

Validate

Historical backfill and data-quality checks run against a shadow environment.

Ongoing

Operate

Pipeline monitoring and incident response under an agreed SLA.

Why tested models, not one-off scripts

Every model reviewed, every run traceable

  • Version-controlled transformations — every model change reviewed like production code.
  • Documented lineage from raw source to the metric on the dashboard.
  • Handed over, not hoarded — your team can extend the pipeline without us in the room.

Column-level lineage built to satisfy an external data-governance audit.

Common questions

Questions we get about data engineering

What warehouse platforms do you work with?

Snowflake, BigQuery, and Postgres are the most common targets — the choice depends on your existing cloud footprint, query patterns, and team's SQL fluency, decided during the assessment phase.

How long does a warehouse build take?

A source-system inventory and priced data model come out of the first two weeks. Full build, including historical backfill and data-quality validation, typically runs 6–8 weeks depending on source count.

Who maintains the pipeline after launch?

Your team can, using the dbt models and documented lineage we hand over — or we continue under an SLA-backed operate phase with pipeline monitoring and incident response.

How do you prevent bad data from reaching dashboards?

Schema and freshness checks run on every model and fail loudly before propagating downstream. Every transformation is version-controlled and reviewed in pull requests like production application code.

Can you integrate multiple source systems?

Yes — engagements have consolidated as many as a dozen source systems into a single warehouse. Each source is inventoried and priced individually during the assessment phase.
