PrivatePrivate repositories are represented through architecture notes, impact, and design tradeoffs instead of source links.
Role
Backend implementation across producers, consumers, schema evolution, and ClickHouse ingestion.
Architecture
- Services publish typed events through Kafka producers with schema validation.
- Consumer groups separate audit persistence from analytics aggregation so each workload scales independently.
- ClickHouse stores query-heavy audit history while Kafka retention preserves replay windows.
Highlights
- Handled multi-million daily event volume with low-latency consumer processing.
- Separated producer retries from consumer idempotency to avoid duplicate audit records.
- Added lag and dead-letter monitoring for operational visibility.
Constraints
Office Project
Company-owned repositories cannot be linked publicly, so the page documents architecture and tradeoffs without proprietary code.
