At DGSOL, I engineered ETL pipelines processing 150TB+ of compressed keyword and SERP datasets, from ingestion and deduplication through transformation and loading into ClickHouse distributed clusters.
I designed high-volume ClickHouse ingestion and analytical queries, including bulk-insert workflows and token-based data retrieval. I also developed Go-based APIs for keyword ranking, trend analysis, and large-scale data retrieval.
At MicroTech, I managed 260+ Linux servers, handling system administration, automation, deployments, and security configurations.
At DevOps—IPTV(satocean), I implemented CI/CD pipelines for PHP and Laravel applications and set up database backups and Prometheus and Grafana monitoring.
