The most amazing...
...project I've completed involved building and leading a team of four engineers that delivered 12 OpenStack clouds for a key customer during a year.
Work Experience
Senior Field Software Engineer
Canonical
- Supervised a team of four engineers that successfully designed, deployed, and handed over 12 clouds for the most significant Russian telco, MTS.
- Restructured the onboarding training course for the sales team, covering the most frequently asked questions. Hence, the onboarding process was simplified and reduced by 50%, going from two months to just one.
- Oversaw more than 15 successfully closed deals and deployed private clouds while acting as the lead engineer.
Site Reliability Engineer
Ingram Micro Cloud
- Amplified the infrastructure-related deployment success rate from 80% to 98–99%.
- Established a consistent hardware inventory and monitoring system across the three physical locations, reducing the incident response time from hours to minutes.
- Implemented the first software development and deployment workflow inside the department. As a result, a mandatory code review and peer approval process have been introduced, reducing the human factor influence.
- Eliminated multiple instances of the deployment artifact storage and merged them into a single source-of-truth repository, reducing the project build time by approximately 20%.
- Drove the company-wide hybrid cloud provisioning. I designed and implemented the connection layer between the existing infrastructure and the Azure public cloud, considering all business requirements, including cost management and analysis.
Experience
Telco Infrastructure Cloud
Migration of the Corporate Environment from On-prem to Azure
After that, the administrative part was initiated, including some of the business processes assessment and adjustment, so we could do the migration as smoothly as possible, ensuring none of the existing workflows were affected.
In the end, I have created a hybrid cloud infrastructure, leaving the most intensive and expensive workloads being computed on-prem and moving all others to the cloud.
