Project history
• I helped my team to manage 2x single node instance databases hosting 20+ applications inside the
company, plus 3x databases as the backend of mobile-bank application for 3 banks (all included
standby instances).
• We improved uptime of databases to a cumulative amount of 30+ percent, by doing some
performance tuning, SQL tuning and erratic design fixes.
As of 2019 I’ve
engaged in DevOps operations:
• We managed to migrate whole DevOps toolchain plus 3 production services to containers and free
up resources on the servers.
• Succeeded to merge 3 sparse git servers.
• Launched multiple solutions to maintain workload efficiency (Antispam, password manager and
more)
• Designed and implemented two production services on top of Swarm.
In addition:
• I directed company’s monitoring system, extended it with 10+ customized templates and some
scripts to suit company’s scenarios. Our efforts led to more than 150 percent increase in product
uptime (cumulatively for 30+ services/microservices).
• With the cooperation of developers, I’ve engagement in debugging parts of product codes issues
(bugs/efficiency issues).
