Work Experience
Software Engineer
SlicePay
- Transitioned to leading the infrastructure team and built Hercules, a job scheduler that is used to run over 200 jobs by every team in the organization.
- Completed the IAAC transition of the whole infrastructure over AWS, including the security, reliability, and cost optimization pillars of a well-architected framework.
- Built internal frameworks for security using internal and external tools, such as AWS Security Hub, Cloud Custodian, and ScoutSuite. Increased observability around VPC flow logs and WAF logs using Amazon GuardDuty and ELK.
- Migrated all the microservices to ECS Fargate with one-click CI/CD deployment for all environments.
