Engineering / Open resources
VMageste — High-Volume Marketing Analytics SaaS
Platform centralising campaigns, leads and analytics from multiple traffic sources in a single dashboard, with lead enrichment and deduplication, alerts and reports.
Migrating without stopping the product
The Strangler Fig pattern allowed replacing the monolith piece by piece, keeping the old system running while each slice migrated — instead of a big-bang rewrite, which is where this kind of project usually dies.
Splitting writes from analytical reads
Asynchronous ingestion over Kafka and analytical querying on a columnar store. The two workloads stopped competing for the same resource, which was the real cause of the slowness.
Clean leads at the door
Enrichment and deduplication happen in the ingestion pipeline, not in a report. The sales team receives an already-cleaned base instead of discovering duplicates while dialling.
