Dheeraj Kumar

I’m an AWS Certified DevOps Engineer (SAA-C03) with 3+ years designing and operating production-grade cloud infrastructure on AWS. I specialize in Terraform-driven Infrastructure as Code, end-to-end CI/CD automation, and container orchestration, with a reliability-first mindset.

In my recent work at Finagle Financial Services, I architected a serverless API data archival pipeline processing 500+ vendor API events per batch using AWS Lambda, SQS, and ClickHouse. I built compliance and security infrastructure using S3 Object Lock (COMPLIANCE mode), KMS encryption, VPC isolation, and dual-control IAM roles to produce immutable PII-redacted audit trails with 90-day queryable retention and Legal Hold.

I also deliver measurable operational improvements through automation and observability. I created production tooling like smoke tests and S3→ClickHouse recovery workflows, implemented failure monitoring with DLQ auto-redrive, and built real-time Grafana dashboards for vendor-specific failure rates, latency percentiles (p50/p95), and daily spend analysis.

Earlier, I reduced release cycle time by 20+ minutes by building multi-stage Jenkins pipelines, and cut system downtime by 15% by standardizing CloudWatch alarm provisioning in Terraform. I’ve supported GitHub Actions pipelines across 10+ microservices, authored Kubernetes deployment assets, and used Python automation to reduce on-call toil and improve MTTR.
