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

2018 - PRESENT
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

2015 - 2018
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

https://ubuntu.com/blog/mts-selects-openstack-and-canonical-for-next-generation-cloud-infrastructure
The largest country mobile operator and a leading media and digital services provider, MTS, has chosen OpenStack for its new 5G infrastructure project. I led a team of four engineers through the successful design and delivery of this project within the given timelines. I also took part in the delivery activities.

Migration of the Corporate Environment from On-prem to Azure

IIn this project's scope, I have designed and implemented the technical connection layer between the existing infrastructure and the Azure public cloud, considering all business requirements, including cost management and analysis.

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.
