Senior AWS Solutions Architect | DevOps/SRE | Kubernetes & Cost Optimization I help startups and scaleups ship faster, cheaper, and safer on AWS. Recent results: reduced production incidents by 62%, cut monthly cloud spend by $38k through rightsizing and gp2→gp3 migrations, and brought deploy time down from 45 min to 6 min with a GitHub Actions + ArgoCD pipeline. My edge: I blend Solutions Architecture, DevOps, and SRE. That means I design clean, scalable systems, automate everything end-to-end, and harden reliability with the right observability and on-call hygiene. Highlights: Designed multi-account AWS setups (EKS, VPC, ALB/NLB, RDS, S3, CloudFront, Route 53) with IaC (Terraform & CDK). Built progressive delivery with Argo Rollouts (blue/green & canary) and automated rollbacks. Implemented cost-savings playbooks (ECS/EKS rightsizing, Graviton, storage class tuning) with measurable ROI. Production-grade observability: Prometheus/Grafana, CloudWatch, alerting SLOs, incident response runbooks. Languages & tooling: Go, Python, Bash, Docker, Helm, Karpenter, KEDA, Istio, APISIX, GitHub Actions. If you need someone to diagnose a flaky pipeline, tame AWS costs, design a resilient architecture, or migrate safely to Kubernetes, I’m ready to jump in and deliver results in days—not weeks.
