Vladimir Carballo

Software Engineer at NA

Led the design and evolution of high-traffic, event-driven platforms. Driven monolith-to-microservices migrations, designed data models for high-throughput databases, and built and shipped fault-tolerant APIs that power core product flows. Led several large-scale database migrations, including zero-downtime horizontal partitioning and archive strategies for SQL replicasets that increased performance by roughly 70% and reduced costs by 35%, and built observability into these systems from the start, establishing dashboards and SLO-driven monitoring to keep latency for critical APIs consistently in the low-millisecond range.
