Learn the work behind Data, AI & Forward Deployed Engineering
Practical explanations, career decisions and reproducible workflows. Read the reasoning, inspect the evidence and follow the next skill into a real programme.
Design a stakeholder dashboard acceptance checklist
A dashboard is ready when intended readers can complete their tasks using trustworthy measures under the correct access and freshness conditions. “Looks good” is useful design feedback, but it is not a complete acceptanc
Design a technical due-diligence checklist for an AI pilot
Technical due diligence is evidence gathering under decision pressure. A checklist should expose which claims are verified, conditional or missing, rather than create a large count of yes boxes.
Design a training dataset contract
A schema lists columns and types. A training contract also defines row grain, uniqueness, timestamps, units, allowed values, freshness and ownership. These semantics determine whether a feature means the same thing acros
Design a user acceptance test for a client simulation
UAT asks whether the service supports the business task under realistic conditions. It should be run by the role that accepts the outcome, even in a fictional simulation.
Design a webhook receiver that tolerates duplicate events
Webhook delivery is commonly at least once. A provider retry after timeout must not create another order, payment or message.
Design an abstention response for missing evidence
“I don’t know” prevents fabrication but may leave the user without a next step. A useful abstention identifies the unsupported decision, states why available evidence is insufficient and routes the user to an allowed sou
Design an approval inbox with explicit ownership
Adding a human approval node does not make a workflow safe if requests disappear into an unowned queue. Approval is an operational product: the reviewer needs context, authority, time and a clear consequence for no respo
Design an approval-required write tool
A write tool should not treat a generated call as authorization. Separate proposal, approval and execution, and invalidate approval when material arguments change.
Design an automation brief before choosing n8n or an agent
Choosing a canvas or agent framework first turns the tool’s features into the process. Start with the business event, decision boundary and accountable owner.
Design an incremental SQL extract with late-arriving records
An incremental extract reads newly available records instead of repeatedly copying the entire source. Its cursor must track availability under a documented source contract. Using business event time as the only cursor ca
Design compensating actions for partially completed operations
A distributed business process cannot usually roll back like one database transaction. When the third operation fails after the first two completed, recovery is a new business process. Compensation must respect dependenc
Design dashboard tooltips that explain a metric
A useful tooltip answers the question a reader has while inspecting a value: what is included, what denominator was used and what qualification matters? Repeating the same large number in a decorative popup adds little u
