Event-Driven Data Pipeline and Analytics Foundation on GCP
Designed and deployed a GCP-based data platform for moving operational data into a cleaner analytics workflow with better reliability, traceability, and downstream consumption patterns.
Purpose
The client needed a more dependable way to move operational data into analytics without brittle point integrations and opaque batch jobs. The project solved that by introducing an event-driven GCP data platform with clearer ingestion, transformation, replay, and quality-control boundaries.
Technical Implementation
- Built the ingestion layer with Pub/Sub topics and subscriptions so source systems could publish events asynchronously without being coupled to downstream transformation timing.
- Implemented Dataflow pipelines in Apache Beam to validate schemas, apply enrichment and normalization steps, and write failed records to dead-letter storage instead of dropping them silently.
- Used Cloud Storage for raw and replayable landing zones, then loaded curated datasets into partitioned BigQuery tables with scheduled quality checks on row counts, null thresholds, and late-arriving data.
- Orchestrated scheduled loads and backfills with Composer, codified the platform in Terraform, and validated pipeline changes with Beam unit tests, sample replay runs, and BigQuery reconciliation queries before production release.
Client Delivery & Handover
The implementation was done with the client data, platform, and reporting stakeholders so source-system assumptions, transformation boundaries, and downstream reporting needs were validated as the pipeline was built. Operational visibility and failure handling were designed with the client team from the start rather than added after deployment. Handover included pipeline flow diagrams, runbooks, data ownership notes, training sessions on monitoring and failure recovery, and documentation for safely adding new sources and transformations later.
Outcome
The client ended up with a cleaner data pipeline architecture, more dependable movement of operational data into analytics, and a platform that was easier to reason about and extend over time.
