  Tech lead in PowerStore Networking team.PowerStore is a Midrange storage system supporting both classical SAN and HCI deployments, providing clustering and HA capabilities.* I led design, development and delivery of business-critical features (e.g. support for NVMe-TCP, user-configured LACP and Fail-Safe Networking, etc) related to networking and storage frontend orchestration, non-disruptive reconfiguration design for storage clusters, HA, network validation.* I worked closely with PowerStore architects and product mgmt; helped serviceability team solve customer issues, improve internal tooling and knowledge base.* I worked at all layers of the product (from deploy scripts (Perl, Python, Bash) up to platform/control plane software and services (C, Golang))* I was technically leading up to 5 x engineers and 3 x QAs and effectively collaborated with geographically distributed teamsKey tech:- Linux networking (vlan, macvlan, ipvlan, bonding, FSN…)- Network technologies (LACP, DNS, NTP, IPv6, mDNS, vxlan, iSCSI, NVMe-oF, Dell OS9/10, Dell SFS, etc)- SW stack technologies: Linux, Docker, Postgres, Pacemaker, C, bash, Python, Perl, Golang, VMware ESXi, vCenter* I worked on a VSA (Virtual Storage Appliance), focusing on public clouds, AWS in particular.* I implemented PoCs of VSA logical networking, floating IPs, automatic IPAM and zero-touch network configuration, and led design and development of these afterwards.Key tech:- AWS EC2, VPC, S3, CloudFormation, IMDS, boto3, and more* I consulted product management, QA and serviceability teams on PowerStore networking architecture.* I was a scrum master* I was a mentor within Dell EMC Mentoring program for University Students, and also mentored engineers inside the team. Show less I worked on automated performance regression testing of midrange storage systems from Dell EMC Unity product line.* I led the design, development and delivery of an advanced scheduling system for efficient parallel execution of performance tests and eventually increased available HW utilization by 30%, increased performance tests coverage;* I developed and maintained frameworks and tools for automated performance testing;* I conducted performance testing of Midrange storage arrays (on-demand, nightly, weekly, release test suites); performed data analysis of the collected telemetry/performance dataI led the development of a cloud-based application PoC for the performance test data management and visualization. Reduced test result processing efforts by 80%, and allowed up to 30% less engineer involvement in performance data processing and visualization. Tech: Microservice architecture and REST API; Java Spring; MongoDB, NFS; Python, Perl;* I led a team of two junior engineers from the idea to a working PoC; basic project management; communication with stakeholders;* I developed system-level architecture, define data/instruction workflows;Still being SME in Energy Star certification for Data Center Storages from the technical side. See the previous job description for more details. Show less Responsible for Energy Star certification for Data Center Storage of the whole EMC Midrange product line (VNXe/Unity) from the technical side.Responsibilities:* automation of certification performance testing and data processing and visualization;* analysis of storage systems' performance data to find the most energy-efficient configurations;* investigation of performance-related issues; working with other teams (Lab, Dev, HW engineering) to investigate complex problems;Certified a number of storage systems (VNX, VNXe, Unity product lines), which allowed EMC to keep leading position on the market.
