• ◈ Microservices Migration to Kubernetes
• Moved microservice from ECS to K8s from scretch using argocd and helm.
• ◈ Setup AWS ECS Monitoring
• Integrated prom client, node exporter, scalyr agent, ecs exporter & ecs service discovery for different types of metrics. Added metric like P95, P99, error percentage, event loop lag, CPU, memory, connection count etc.
• Saved $3,000 monthly by setting up ecs exporter and disabling AWS default container insights.
• ◈ Self Managed Cluster Redis Setup & Migration
• Setup fully automated clusterredis with self healing & failover mechanism
• with Ansible and Terraform.
• Migrated data from existing standalone redis instances to clusterredis
• with 0 downtime.
• ◈ Mongo Analytics Pipeline (Debezium Alternative)
• Built a inhouse tool which replaces debezium real time streamig to batch streaming.
• By replacing Debezium and stopping all Kafka pods, we have saved around 10 lakhs on a monthly basis.

• ◈ Personal Identifiable Information (PII) Encryption
• Build centralized system to encrypt and decrypt PII data, and encrypted
• collection having 2.7cr customer and 1.2cr partners data with 0 downtime.
• ◈ Load Testing
• Build load testing framework with user friendly dashboard to load test
• APIs, for peak season readiness. Done load testing at 5x traffic for 200+
• microservices, to figure out the bottleneck at infra and microservice level.

• ◈ Infrastructure as a Code ( IAAC )
• Migrated Logging(ELK, kafka) and Monitoring(prom, grafana, thanos)
• Stack to a different VPC and setup new EKS cluster, with zero downtime.
• Onboarded all AWS Networking(Vpc, subnets, routes, Nat, Igw, Nacl,
• securityGrps etc.), cloudflare DNS to Terraform, with zero downtime.
• Cleanup of total 258 stale security groups & 968 stale security group
• rules, which were present in the system since UC networking was build.
• ◈ Distributed system
• Worked on Alerting System, to configure custom(elk&prometheus
• queries) & standard(latency,error,throughput&consumerLag) alerts.
• Worked on distributed rate limiting and load shedding framework, to
• dynamically configure rate limit and load shedding.
• ◈ Cost Optimization
• Build a system which can detect and clean unused and overprovisioned
• AWS resource. Saving of 870$ as a kickstart and set system in automode.
• Build AWS cost tracking system to detect any anomaly in cost, with
• visualization on grafana and alerting on, deviation at different cuts and
• overall cost per delivery.
• ◈ Internal Tools
• Worked on Anomaly Detection to reduce mean time to find the RCA for
• developers when system goes down, and to figure out the root cause.
• Worked on Microservice benchmarking framework which is use to give a
• score to backend microservices, based on different parameters like(UT’s,
• latency, uptime, errors dependency).
• ◈ CICD
• Worked on Setup service which is use to create a new microservice via
• jenkins job and deployment framework for deployment of microservices.
