• 1. Led performance infrastructure setup under Razorpay’s new Cell
• Architecture, utilizing Terragrunt/Terraform.
• a. Onboarded 30+ services and ran 10+ performance suites across varied
• business flows - tuning k8s service configurations — CPU, Memory, RDS
• related configs — for optimal performance.
• b. Accelerated onboarding using CursorAI to write and validate Terraform
• modules for new service setups, reducing development time and
• manual errors.
• 2. Led Kafka migration from Strimzi-managed Kafka to AWS MSK - taking
• care of all infra related issues during migration.
• 3. Drove org-wide resolution of a major security vulnerability targeting
• Amazon AMIs called whoAMI - detected risky AMI-fetching pattern
• enforced safety using Semgrep rules and Allowed AMIs feature flag.

• 1. Led DDoS Simulation Program:
• a. Collaborated with 10+ pods to simulate attacks on 30+ critical APIs.
• b. Strengthened system resilience through preemptive detection of
• system throttling capabities and AWS WAF configuration
• deficiencies.
• 2. Spearheaded Chaos Engineering Charter using Chaos Mesh:
• a. Simulated Kubernetes-level failures (pod/network/node disruptions)
• figuring out service level config issues and fixing the same for the org.
• 3. Led multiple cloud cost optimization initiatives:
• a. RDS, Elasticache: automated lifecycle scripts using Pulumi.
• b. Secrets handling: implemented DynamoDB-backed fetch
• mechanism for lightweight retrieval.
• 4. Executed critical performance validations for various Migration activities
• gaining deep knowledge on the respective setups:
• a. RDS → Aurora Migration
• b. Graviton3 EC2 Migration
• 5. Developed Card Tokenization Load Suite to simulate user migration
• during the switch to Tokenised Cards mandated by RBI.
• 6. Architected an ephemeral perf environment to reduce infra cost,
• provisioned dynamically for test runs using Pulumi.
