Event streaming pipelines → Kafka, NATS JetStream, billions of events/day
Real-time reporting systems → ClickHouse, BigQuery, sub-second queries on TBs

- Optimization over vertical scaling — finding what's actually slow, fixing it, not just adding capacity
- Reliability at scale — systems that hold up when it matters, not just in staging
- Cost-efficient architecture — infrastructure that grows with the business without the bill doing the same
- Fintech & AI infrastructure — where I'm focused next
Google Summer of Code 2017 — ownCloud

Available for remote backend/infra roles and fractional CTO engagements.
