n8n Workflow Automation
Orchestrate repeatable operational processes with visible logic and explicit ownership.
02 / n8n Automation Systems
Automate operational work without losing control.
D2 designs n8n workflows, API integrations, data pipelines and AI-assisted systems around business events, durable state, deterministic rules, failure recovery and clear ownership.

Automation use cases
Start from the operating constraint, not from the n8n node list.
D2 chooses workflow orchestration, API calls, database state or custom code according to what the process needs to remain reliable and understandable.
API & Webhook Integration
Connect systems through authentication, pagination, mapping, validation and controlled synchronization.
AI-Assisted Workflows
Use models for classification, extraction or drafting while deterministic controls remain outside the model.
Data Pipelines & Reconciliation
Normalize, validate and persist business data before it reaches reporting or another system.
CRM / Lead Operations
Enrich, score, assign and follow up leads across forms, CRM, email and internal notifications.
Reliability & Infrastructure
Design retry, idempotency, observability, queueing, worker separation and recovery around workflow execution.
Engineering mindset
The workflow is the output. The reasoning is the engineering.
Define the event and source of truth
Know what starts the process, where durable state lives and which system is authoritative.
Keep deterministic decisions explicit
Use AI where interpretation helps; keep routing, validation, ownership and SLA logic inspectable.
Design failure before deployment
Retry, idempotency, alerts, replay and recovery paths are architecture decisions, not afterthoughts.
Implementation proof
Architecture, implementation evidence and explicit claim boundaries.
D2 publishes what a workflow actually demonstrates and separates that from production metrics that are not evidenced.
