Swiss B2B Pipeline Rewrite
Cloud database pipeline rewrite for a Zurich-based Series A B2B SaaS. Slashed queue bottlenecks under high concurrent load and cut global infrastructure costs by 62%.
The Context
Heavy multi-tenant background data ingestion jobs were saturating PostgreSQL database connections, triggering cascading lockups.
To compensate, the client's GCP Cloud Run instances were scaling aggressively, ballooning the monthly infrastructure invoice to unsustainable levels.
What I built
- Go scheduler rewrite. Replaced the legacy scheduler with a high-performance Go transaction pooling engine using batched inserts and transaction isolation loops.
- Query caching. Architected a single-origin Redis cache that reduced redundant read operations by 85%.
- Bill cut. Slashed GCP cloud infrastructure bills by 62% (from $14k to $5.3k monthly) while simultaneously lowering database queue processing latency.
By the numbers.
If we worked together.
I bring high-leverage product engineering and absolute operational discipline: shipping weekly, pressure-testing user inputs, and automating delivery pipelines.
