Data Engineering

Senior Data Engineering That Ships in Your Repo, to Your Standards

You need pipelines built, models refactored, a warehouse migrated, or a platform stood up and your open requisition has been on the careers page for a quarter. We deliver data engineering work as a team, not a body shop. Senior practitioners on Snowflake, Databricks, Microsoft Fabric, Azure, and the modern data stack, shipping production code in your Git, to your standards, with handover built in.

Where Hiring Your Way Out Stops Working

You’ve been trying to hire a senior data engineer for four months. The job is still open.

The roadmap has ten priorities. Your current team can staff two of them.

Contract engineers come in, ship something, leave. The code is unreadable by anyone on your team.

Your pipelines work but weren’t built to be extended. Every change is a rewrite.

You need platform-level engineering warehouse, lake, CDC, semantic layer not just script-writing.

Where Are You Starting From?

Need pipelines built on Azure Data Factory, Airflow, or Fivetran

Pipeline Engineering

Need a cloud warehouse built or extended

Warehouse Engineering

Need a data lake or lakehouse implementation

Lake & Lakehouse Engineering

Need change data capture (CDC) from operational databases

CDC & Streaming Engineering

Need DBT or transformation code written and structured properly

Transformation Engineering

Need to migrate from on-prem to cloud

Migration Engineering

Need platform-level work governance, cost, observability

Platform Engineering

Need short-term capacity while we hire

What Changes After We Engage

Six scenarios the buyer can picture.

Your roadmap starts moving in week two

The engagement kicks off Monday. By the following Wednesday, the first pipeline is in your staging environment with tests and CI/CD wired up. The roadmap tracker shows green for the first time in a quarter.

Code lands in your Git, to your standards

Every commit goes through your PR process. Your engineers review it. Naming conventions, folder structure, and test coverage match your existing code, not a contractor's template.

Senior practitioners on the problems that need them

The model design gets done by a staff-level data engineer who's built five like it, not a junior learning on your project. You don't pay for the learning curve.

The code your team inherits is extensible

Six months after we leave, your engineers add a new source. They do it in two days using the patterns we set up, not two weeks rebuilding context from scratch.

You don't wait four months to start

Your candidate pipeline is empty this month. The engagement starts in ten working days. The platform work that was queued for Q3 is already running by mid-Q2.

Handover is part of the work, not an afterthought

Runbooks, documentation, and training sessions are in the scope from day one. When we leave, your team has the codebase, the design rationale, and the confidence to extend it.

How We Engage

1

Discovery week and environment setup

We scope the work in a single discovery week reviewing your stack, your standards, your Git conventions, and the three highest-priority roadmap items so engineering starts in your environment, not against our template.

2

Deliver in two-week increments

We ship in two-week sprints with code review by your engineers every sprint, production-ready output every cycle (not a big-bang handover at the end), and quality, documentation, and tests as default outputs of every commit.

3

Handover with runbooks and decision docs

We hand over with runbooks, architecture decision records, and training sessions so your team owns the codebase when we leave, without needing us on retainer to make the next change.

Your Open Requisitions Aren't the Problem. They're the Reason Nothing Ships.

Book a data engineering review. We’ll scope the work, match the right senior engineers, and start shipping against your roadmap inside two week

Umair handled my problem timely and efficiently. He is easy to collaborate with and I will be using him again.

Super good explanation, patience and a good sense of indagatory about the data, sources, etc. The solutions suggested were very safisfactory.

It is always a pleasure to work with Umair and his team. Rock start service!

Honestly, this has been an outstanding experience from start to finish. The team went far beyond my expectations — not only did they understand a very complex real-world operation, but they were also able to translate it into a functional and well-structured system. Their communication, patience, and willingness to adapt to my requirements were truly impressive. What I appreciated the most is how committed they were throughout the entire process. They were always available, proactive, and focused on delivering real value, not just completing the task. The system works great, and you can tell there is a lot of thought and effort behind it. This is not just a basic delivery — it’s a solid, professional solution. I would 100% recommend working with them, and I’m definitely looking forward to continuing this project long-term. Great job to the entire team.

Got Questions?

Will you work to our code standards, or will we inherit something alien?

Your code standards, your Git conventions, your PR review process. Discovery week is partly spent documenting your standards and matching them in the first sprint. If your team can’t read, review, and extend our code, we haven’t done the job.

Can we scale the team up and down by the week?

Two-week increments — scale up between sprints, scale down at the end of a sprint. We don’t lock you into annual commitments. The engagement size matches your actual work, which changes over the quarter.

Do you work on our repository, or in a separate environment?

Your repository, your cloud subscription, your staging and production environments. We don’t ship work in a sandbox and hand it over later. Everything lands through your PR process with your security controls from day one.

What's the difference between your engineering services and a staff-aug agency?

Staff-aug sends bodies by the day. We deliver outcomes with a team — a staff-level lead, practitioners matched to the work, a shared Git repo, and a defined scope. You get senior judgement on what to build, not just capacity to build whatever you spec.
