Ways to Work With Us
Scoped Project
A defined build with a clear end. Examples from our case studies: replacing a legacy ETL tool, building a warehouse or lakehouse from scratch, or fixing a data stack someone else built.
Team Engagement
When the scope needs more than one engineer. Aline and Lorena lead and stay your point of contact. For bigger scopes we extend with senior engineers we vet, who work to the same quality and documentation standards. This is the Strategic tier: monthly planning, quarterly data health and cloud cost reviews, governance setup, a 90-day roadmap, and team training.
Ongoing Maintenance
After the build, pipeline monitoring, new integrations, and fixes on a smaller retainer, so what we built keeps running without becoming a full-time line item.
Tool-agnostic. We work with the stack you have, or help you pick one.

Common Questions About Data Engineering Consulting
What does a data engineer consultant do?
A data engineer consultant assesses your current data setup, designs the right architecture, and builds the infrastructure to run it: pipelines that move data reliably, a warehouse that centralizes it, and clean models your team can trust. Ours are hands-on: we own the delivery, document it, and hand it off so your team can run it without us.
Do you only advise, or do you build too?
We build. Advisory-only consulting leaves you with a plan and no one to execute it. We design the architecture and then implement it: setting up the warehouse, building the pipelines, connecting your sources, modelling the data, and adding quality checks. Strategy and execution come from the same team, so nothing gets lost in translation.
Can you provide a team, not just one engineer?
Yes. Aline and Lorena lead every engagement and stay your point of contact. When a scope needs more than one engineer, we extend the team with senior engineers we vet ourselves, who work to the same quality and documentation standards. That's the Strategic tier: a team engagement plus monthly planning, quarterly reviews, and a 90-day roadmap.
How is this different from a data engineering agency?
Most agencies staff junior engineers at senior rates and rotate you through account managers. With us, the people who scope the work are the people who build it, start to finish. No hand-offs to someone you've never met, no black-box deliverables. Everything is documented so your team isn't dependent on us afterward.
How much do data engineering consulting services cost?
It depends on the scope and the size of the team the work needs, with a 3-month minimum on every engagement. One data lakehouse we delivered came in 40% under budget and runs on about $12,000 a year in infrastructure cost. Run your own numbers in our fractional vs. full-time cost calculator to see how a scoped engagement compares to a full-time hire.
