Data Platform
Backend rebuild with 99.9% uptime
16 weeks Migration time-60% Query latency99.9% Uptime SLA
The Challenge
The backend couldn't handle 10x data volume growth. Query latency was degrading and the monolithic architecture blocked independent scaling.
Any downtime during migration would breach customer SLAs and trigger penalty clauses.
Our Approach
Five backend engineers with PostgreSQL, Kafka, and Go expertise redesigned the data pipeline with event sourcing and comprehensive monitoring.
Blue-green deployment strategy ensured zero downtime during the 16-week migration.
The Outcome
Migration completed with 99.9% uptime maintained, 60% query latency reduction, and independent service scaling enabled.
The platform now handles 10x previous data volume with room for further growth.
