Start with one question
A rising bill, a failing DAG or an architecture decision. Agree the question, evidence and representative workflows before access.
BIGQUERY / GOOGLE CLOUD
Understand the problem. Choose the next move.
Focused review of your BigQuery data platform and selected Composer/Airflow pipelines. Connect cost, reliability and architecture to a practical next step.
Describe your project
Scope, availability and price agreed before work begins.
Connect spend and operation
Review BigQuery jobs and selected Composer/Airflow dependencies, schedules, retries and refresh needs. Connected services are included only where agreed.
A decision you can act on
Document findings, uncertainty, priorities and the next intervention. Discovery has an agreed hours cap; extensions require approval.
DELIVERABLE SAMPLE / FICTIONAL DATA
IllustrativeA documented decision your team can review.
An extract showing how a single-workflow review could be presented. A sample of the format and reasoning, without client results.
- Question
- How can retries avoid duplicates and preserve late corrections?
- Evidence to review
- SQL, job history, DAG runs, keys and when the business needs the table.
- Illustrative finding
- Appending the same batch twice duplicates orders; filtering only by order date misses later corrections.
- Proposed decision
- Validate immutable batches and update by key and version, comparing the result with an independent reference.
- Acceptance
- Reconcile keys and values against the reference; replay without duplicates; include a late correction.
- Risk and next step
- Confirm update and deletion semantics. Agree the late-data window and rollback before implementing.
A real handoff identifies sources, period, uncertainty, priorities, owners and agreed checks. Contents depend on scope; the review may recommend implementing, investigating further or stopping.
HOW IT WORKS
A clear first step. Room to build trust.
Start by email. Agree the work. Keep decisions and documentation in your hands.
- 01
Describe the problem
Share the context in writing. The initial fit check by email is free; a technical conversation can be arranged when useful.
- 02
Agree a first engagement
Get scope, deliverables, access, dates, acceptance criteria and the total price. Accept the proposal and pay online through a private link.
- 03
Check the improvement
Receive documentation of the work and how to validate it. Continue with planned support if useful. Production changes require authorisation, tests and rollback.
LET’S START WITH THE CONTEXT
What would you like your data platform to do better?
Tell me what is happening and the outcome you need. My first reply will confirm the fit and a next step, or ask for the details needed to define it.
- No mandatory sales call
- No credentials needed to inquire
- No payment before an agreed scope
