• At Quikr, a large-scale online classifieds platform, I was part of the Infrastructure Management team responsible for designing, operating, and supporting high-availability production environments serving high-traffic consumer workloads. The infrastructure primarily leveraged Linux/UNIX, AWS, and open-source technologies, aligned with business availability and performance requirements.
• I worked on automating operational tasks and infrastructure workflows using Python and shell scripting, reducing manual effort and improving system reliability. I was involved in deploying and managing production environments using technologies such as Apache, Nginx, HAProxy, and Elasticsearch, along with NoSQL data platforms including MongoDB and Couchbase to support scalable application workloads.
• I configured and managed CI/CD pipelines using Jenkins and Bitbucket/Git, enabling automated builds and deployments. My responsibilities included OS-level security hardening, performance tuning, system monitoring, and infrastructure upgrades across both physical and virtualized environments.
• I supported a wide range of Linux distributions (RHEL, CentOS, Ubuntu) and managed core services such as MySQL, web servers, caching layers, and messaging components. I was also responsible for provisioning and maintaining physical servers, virtual machines on VMware ESX, and cloud instances on AWS, including network and access configuration.
• As part of the on-call rotation, I handled production incidents, technical escalations, and cross-team coordination to ensure rapid issue resolution. I regularly analyzed system bottlenecks and recommended infrastructure and architectural improvements to enhance performance, stability, and operational efficiency.

• At ibibo Group, I was responsible for operating and supporting production Linux and cloud infrastructure for high-traffic consumer applications. My role focused on ensuring system availability, performance, and security across on-premise and AWS environments supporting business-critical workloads.
• I managed day-to-day Linux administration, including user and access management, file systems, performance monitoring, system security, authentication, and scheduled job management. I supported CDN operations, cache invalidation (Varnish), and FTP services, ensuring smooth content delivery and operational stability.
• I worked on CI/CD tooling using Hudson and Git, automating operational and deployment tasks through shell scripting and supporting frequent production releases. I was involved in provisioning and hardening operating systems, including RAID configuration, OS installation, and security baselining for production systems.
• I contributed to the design, engineering, and administration of Linux and cloud infrastructure on AWS, managing services such as EC2, VPC, Route53, CloudFront, S3, Auto Scaling, and IAM. I supported physical-to-cloud migration efforts, helping teams transition workloads to scalable and resilient cloud architectures.
• My responsibilities also included configuring and operating core application infrastructure components such as LAMP/LEMP stacks, Apache, Nginx, Nagios, Splunk, Varnish, Memcached, and HAProxy, providing monitoring, performance visibility, and operational support for production systems.

• I started my career at Lenskart as a Linux Engineer, where I built a strong foundation in production infrastructure, operations, and reliability for high-traffic e-commerce systems. I worked closely with Release Operations, Development, and QA teams to support frequent production releases and ensure system stability and performance.
• I was responsible for configuring, operating, and monitoring production Linux servers, using tools such as Nagios, New Relic, Splunk, and Google Analytics to track system health, application performance, and user behavior. My day-to-day work included log rotation and analysis, network troubleshooting, and performance monitoring across CPU, memory, disk, and I/O.
• I supported application infrastructure based on LAMP/LEMP stacks, managing Apache and Nginx servers behind hardware and software load balancers. I also worked extensively with caching and content delivery systems, including Varnish, Akamai, and AWS CloudFront, handling cache purges and traffic optimization.
• My responsibilities included backup and recovery operations using MySQL backup and replication, rsync, and AWS S3, as well as package management using RPM and YUM. I configured and maintained CI/CD tooling using Hudson and Git, supporting build and release workflows.
• I managed DNS records across multiple platforms, including AWS Route53 and internal DNS systems, and coordinated with external service providers following defined escalation processes to resolve production issues.
• During this period, I invested heavily in building deep Linux expertise and earned internationally recognized certifications including RHCSA, RHCE, and RHCA, which laid the foundation for my later growth into cloud, platform engineering, and SRE roles.
