   Arista Networks

   Jul 2021 — Present · Bangalore Urban, IN

   Developing scalable backend solutions using Golang and Kubernetes, focusing on container orchestration, storage management with Btrfs, and secure runtime environments. Improved developer workflows, reduced security incidents, and optimized resource utilization to support multi-tenant systems effectively.• Developed A4-Containers, a container orchestrator Microservice deployed on Kubernetes that reduced workspace creation time from 30 minutes to under 1.5 minutes by automating image building, setup, networking, load balancing, storage, and cleanup, improving developer efficiency by 95%.• Leveraged Linux namespaces to isolate processes and ensure data segregation, reducing unauthorized access incidents by 97%(from 100 per month to 3).• Developed and maintained storage solutions using the Btrfs file system; created a Golang-Btrfs library to manage quotas and volumes through optimized Linux syscalls.• Applied Linux Cgroup CPU/RAM limits in conjunction with Btrfs quota to optimize resource allocationwhich scaled server capacity from 9 to 95 users, achieving a 90% reduction in noisy neighbour incidents (from 100 per week to 10 per week).• Engineered an advanced Mosh multiplexer in Golang, capable of handling 10+ simultaneous Mosh sessions per user across separate instances while maintaining optimal performance, used by over users.• Implemented a Grafana reconciler to manage user notifications, automating alerts that reduced manualintervention by 80%, saving 10 developer hours per week.• Pioneered the use of Kata Containers in developer environments, enabling secure isolation for privileged workloads (e.g. Docker-in-Docker), reducing container breakout risk by 90% and supporting over 500 secure developer workspaces.• Integrated Redis as a distributed cache, reducing query time by 70%.• Engineered a Kafka-based asynchronous processing system for image builds, reducing P90 post-project build/rebase times from 75 minutes to 30 minutes.
