DATA YOU CAN BUILD ON

WHAT THEY OWN

The data platform your team can actually rely on.

01

Ingestion & ELT pipelines

Connectors and ELT jobs that pull from your apps, databases, and third-party APIs into one warehouse, then transform with dbt into clean, versioned, documented models.

02

Lakehouse & warehouse modeling

A layered warehouse or lakehouse (staging, core, marts) with clear grain, tests, and ownership, so every table has one meaning and one team accountable for it.

03

Real-time streaming (Kafka / Flink)

Event pipelines on Kafka or Flink for data that cannot wait for a nightly batch: live metrics, fraud signals, and operational feeds with exactly-once handling.

04

Data quality & observability

Automated tests, freshness and volume checks, and alerts that catch bad or late data before it reaches a dashboard or a model, not after a stakeholder does.

05

Orchestration & scheduling

Airflow or Dagster DAGs that run jobs in the right order, retry on failure, backfill history, and give you a clear view of what ran, when, and why it broke.

06

Governance, lineage & cost control

Column-level lineage, access controls, and a catalog so people find and trust data, plus warehouse tuning that keeps compute and storage spend in check.

SCOPE, MADE CLEAR

Where a data engineer fits, and where they don't.

"Data" gets used as a catch-all, which is how projects end up mis-scoped. The clean map: a data engineer builds the pipes, a data scientist finds the insight, an ML engineer productionizes the model, and an AI engineer ships product on top.

Data Scientist

Builds models and finds the insight in data: forecasting, churn, experimentation.

Data engineer: A data engineer delivers the clean, tested data the scientist then models.

See that role →

Data Analyst

Reports on what already happened with dashboards and descriptive analysis.

Data engineer: A data engineer builds the pipelines and tables the analyst reads from.

ML / MLOps Engineer

Productionizes, scales, and monitors models as reliable services.

Data engineer: A data engineer feeds those models fresh, trustworthy features and data.

See that role →

AI Infrastructure Engineer

Runs the GPU, serving, and platform that AI product ships on.

Data engineer: A data engineer owns the data platform underneath it, ingestion to warehouse.

YOU NEED THIS HIRE IF

Your data is scattered across tools and no one fully trusts it

Analysts wait days for data that should be ready every morning

Pipelines break silently and you find out from a wrong dashboard

There is no single source of truth, every team has its own numbers

Your data scientist spends most of their time cleaning data, not modelling

OUTCOMES YOU CAN MEASURE

A trusted single source of truth every team reads from

Fresh, tested, documented data that lands on schedule

Pipelines that retry, self-heal, and alert before users notice

Lower warehouse spend from tuned models and queries

Analysts and models unblocked, working from clean data

QUESTIONS BUYERS ASK

Straight answers before you commit.

Batch or streaming, which do we need?

Most teams need solid batch first: reliable nightly or hourly loads into a clean warehouse cover the large majority of analytics and reporting. Streaming is worth the extra complexity only when a real decision cannot wait, live fraud checks, operational dashboards, or user-facing features. On the call we look at your actual latency needs so you do not pay for streaming you will not use.

Which warehouse or lakehouse should we pick?

It depends on your data volume, team skills, and cloud. Snowflake and BigQuery are strong managed warehouses for most analytics; Databricks and a lakehouse fit heavier data science and large unstructured data. We assess what you already run and what your workloads need, then recommend one, rather than pushing a favourite.

How long until a first reliable pipeline?

For a scoped source landing in a clean, tested set of tables, a first pipeline is usually running within the paid one-week trial. Broader platform work, many sources, streaming, or a full remodel, takes longer, but we sequence it so you get a trustworthy first slice early instead of waiting months for everything at once.

How do you handle data quality and testing?

Every model ships with tests: not-null, uniqueness, accepted values, and referential checks, plus freshness and row-count monitors on the pipeline. Bad or late data raises an alert and, where possible, is quarantined before it reaches a dashboard or a model, so problems are caught at the source, not by a confused stakeholder.

Who owns governance and lineage?

A senior data engineer sets it up and your team runs it: column-level lineage so you can trace any number back to its source, a catalog with owners and definitions, and access controls that fit your compliance needs. The goal is data people can find, trust, and use without asking around.

What about IP, replacement, and timezone?

NDA and IP assignment are signed before onboarding and everything produced belongs to you, including trial work. If the fit is wrong, Devlyn provides a free replacement with a documented handover. Engagements are planned with overlap for your working hours, in English, every day.
