• Orchestrated a comprehensive K8s revamp project encompassing Compute, Networking, Storage, Monitoring, and Logging layers; achieved enhanced reliability and stability across the entire K8s stack, minimizing downtime and improving system reliability.
• Architected and deployed an innovative one-click production-ready K8s provisioning system, automating the setup of EKS clusters within a remarkable timeframe of 25 minutes.
• Optimised deployment efficiency, reducing manual effort by 80% and accelerating project delivery.
• Led the project of an automation framework leveraging Cookiecutter, Python, Github APIs, ArgoCD and Kustomize to streamline containerization, K8s manifest generation, and ArgoCD onboarding, resulting in zero developer effort and reducing deployment time and increasing software release velocity
• Led the successful deployment of a high-capacity monitoring infrastructure leveraging Victoria Metrics (Prometheus-based), supporting the seamless processing and analysis of over 600k+ datapoints per minute on a single cluster, enhancing operational efficiency.

• Worked on setting up, performance tuning, monitoring and alerting of large scale sharded MongoDB clusters.
• Architecting and moving the entire production workload to EKS (Kubernetes) from VMs. Worked on setting up CI/CD pipelines on Gitlab.
• Optimised costs and increased performance of the application stack on K8s by -
• Building applications on top of ARM64 architecture and running them on Graviton EC2 on AWS.
• Onboarded applications to use Spot AWS machines on K8s to reduce costs with no Zero impact/downtime. One of the very early adopters of Spot machines on K8s.
• Administration and management of large datasources like Kafka, Elasticsearch, MongoDB, MySQL and Redis.
• Worked on cutting down the infrastructure cost by 30% while the market was down during COVID-19.
• Moved the entire Infra monitoring stack from Datadog to Prometheus.
• Have worked on setting up scalable reverse-proxy infrastructure using HAProxy and Nginx.
• Moved our biggest datastore from Elasticsearch to ScyllaDB, which resulted in a massive cost reduction with much better query performance.
• Routine security, system updates to entire infrastructure.

Mar 2018 – Sep 2019 · 1 yr 6 mos · Bengaluru Area, India

• Expertise and production hands on experience with container orchestration tools like Kubernetes using EKS. Deployment through helm charts.
• Built high throughput kafka and zookeeper cluster with 15+ nodes, wrote scripts to manage and monitor uptime of these clusters.
• Worked on setting up highly scalable monitoring infra (Graphite and Prometheus) to handle high IO throughput. Implemented disaster recovery to backup/restore metrics.
• Worked on setting up a customised on-premise Data Centre. Networking, bootstrapping applications, orchestrating and blue green deployment.
• Worked with NoSQL databases like DynamoDB / Aerospike / MongoDB clusters which includes Setting up, Performance optimization, Monitoring and Alerting.
• Worked on setting up log-aggregation system with Graylog and Fluentd.
• Extensively worked on cutting down AWS costs by setting up right observability tools to track costs and optimise resource usage. Ex: unused resources, untagged resources, unused volumes, reservation expiry alerts etc..
• Infrastructure capacity planning, as most of our workloads run on AWS. Heading capacity planning meeting with Architects/stakeholders to finalise on what ratio of OnDemand/Spot/Reserved instances to use for each project to cut down costs.
