## About

```text
At MelliGold, I built Titanium, the company’s first data platform, as its sole engineer and architecture owner. I replaced direct Metabase queries against production Postgres with a streaming pipeline from Postgres through CDC, Kafka, and Flink to ClickHouse, delivering sub-second latency from database commit to queryable data.

At Digikala, I engineered a real-time analytics platform ingesting backend CDC data and frontend events into ClickHouse, and developed pipelines to connect those events with OLTP records. Earlier at DrNext, I worked on data infrastructure and analysis, and at Alibaba Travels Co. I modeled an employee insurance request process using BPMN2 and BizAgi. I’m moving toward ML and LLM platform engineering.
