At Data Driven Lab, I administered 13 production servers for a broker's MetaTrader 4/5 trading platform, monitoring them with Zabbix and Grafana. I investigated trading, connection, and transaction incidents by matching PostgreSQL records with server logs.
At Brokeree Solutions, I supported international broker clients in English and helped configure MetaTrader 4/5 plugins for their requirements. I reproduced issues with logs, SQL queries, and REST API requests, then documented evidence and expected results in Jira bug reports.
Earlier, at Rostelecom, I investigated service-quality incidents and diagnosed customer PPPoE connection problems. At Telia Carrier Russia, I handled IP and DWDM backbone incidents, diagnosing equipment faults and coordinating repairs.
