Senior data engineer focused on time-series databases, IoT data pipelines, financial high-frequency data, and observability.
Background
| Domain | Experience |
|---|---|
| Time-series DBs (QuestDB / InfluxDB / TimescaleDB / ClickHouse) | 8+ years |
| IoT & sensor data pipelines | 6+ years |
| Financial high-frequency data (tick / L2 / OHLC) | 5+ years |
| Observability & monitoring (Prometheus / Grafana / QuestDB) | 5+ years |
Writing Principles
- Every code example is verified runnable in a real QuestDB environment (Docker container)
- Performance claims always include test conditions (hardware, data scale, date)
- No exaggeration, no speculation — unmeasured data is explicitly labeled “estimated”
- Independent technical community, not an official QuestDB project
