Engineering Unit Lead

SberMarket

Moscow, Russia

SberMarket — is the #1 in e-grocery market in Russia in 2021-2022.

I lead an engineering in the field of hiring couriers, pickers, etc. as part of the OpsTech department. This is the brand-new unit of 3 teams and 25+ engineers. Our work is essential to the success of the company, because without sufficient amount of couriers and pickers we won't be able to fulfill all orders of our customers.

For the first year I was leading engineering in the field of Client Orders Assembly as part of the OpsTech department (4 teams with 20 engineers).

Key achievements:

• All stuck projects were completed by the end of Jan. 2023 (first 5 months in company). This resulted in 20%+ growth in key metrics of operations efficiency and huge savings for SberMarket. In the beginning, all projects were in delivery for 3 to 9 months with no transparency and without any releases.
• Set up a transparent and efficient delivery process. In Q1-Q3 2023 we delivered 96% features on time with ~50 days median Time to market.
• DORA metrics in Q2-Q3: 2-3 releases per day, CFR <4%, TTR <15 min.
• Launched initiative to move Orders Assembly from the company-wide Ruby monolith to Go microservices as part of SberMarket's MSA transformation. As for Sept. 2023, this is one of the most efficient and transparent project in MSA transformation in company.
• Reduced blockers and rework in feature delivery by introducing engineering design guidelines and definition of ready for features for OpsTech department (20+ teams).
• Reduced incidents in production caused by releases by introducing lightweight release guidelines for OpsTech department (20+ teams).
• Boosted teamwork culture to the next level by making teams more self-organizing.
• Formed a team of highly skilled teamleads: replaced 2/4 with new-hires, raised 2/4.
• Design observability metrics for Order Assembly business-processes, so everybody in business and tech can see degradation in terms of technical issues and operations efficiency.

Key technologies and practices: Go, Ruby, PG, Redis, Gitlab CI, Grafana, TBD, DDD, Agile, Kanban, SCRUM.
