• Managed, administered and monitored 7000 bare-metal servers, 5000 VMs and workstations running Linux and Windows OS that supported trading. • Utilized system metrics from graphite to map network stats on Grafana to understand packet retransmissions on quantative research servers. • Automated Linux OS provisioning by developing modules in the internal build system, reducing manual configuration and ensuring environment consistency across deployments. • Measured and analyzed latency with different BIOS settings on Dell Servers. • Performed provisioning/decommission, access management and troubleshooting performance issues on reported systems and provided short term fixes and long term solutions. • Tested Solarflare, AMD, Mellanox NIC for round trip latency on multicast and TCP traffic, including upgrading drivers and low-level user space stack (Solarflare Onload) • Developed Python and Bash scripts to automate cluster health checks, firmware verification, and node lifecycle tasks across datacenter racks.

Developed and managed the lifecycle of 5G core Microservices on Kubernetes clusters, ensuring they were production-ready using Helm. Analyzed and troubleshot 5G core network issues using Wireshark, incorporating integrated monitoring systems for efficient fault management. Implemented a robust backup and restore strategy for Container Network Function, which not only bolstered reliability but also minimized data loss. Through this, I also conceptualized and executed shell scripts that automated processes, saving over 20 hours weekly. Conducted and streamlined 100 Automated Acceptance Tests for each Microservice. This transformation reduced deployment time, optimized network performance, and slashed costs by up to 60%. Incorporated REST APIs and shell scripts to automate client provisioning, dramatically cutting down provisioning time and enhancing operational efficiency. Improved the DNS software by performing 5 critical upgrades on an OpenStack Virtualized environment that was live. This initiative led to a 30% reduction in upgrade time. Prepared comprehensive Method of Procedures (MOPs) documents, ensuring future configuration changes had a clear and standardized reference, aiding the Integration team. Collaborated with diverse teams to understand project requirements, effectively translating business objectives into actionable technical specifications, ensuring the successful delivery of projects.

Collaborated with a testing team for a Ukrainian telecom's BSS project (February-April 2020). Learned Cloud and Virtualization from organizational training. Studied Packet core concepts through company training.

• Explored Microcontroller functions through hands-on projects. • Studied semiconductor applications in power electronics. • Learned VLSI system design and research methods.
