Summary

AWS-certified Cloud/DevOps engineer and recent Computer Engineering graduate, with 6 years of frontline operations leadership. Build production-grade AWS infrastructure as code — Terraform + GitHub Actions with OIDC (zero static keys), serverless-first, with observability and cost hygiene built in. Standout project: an AI-assisted SRE incident-analysis pipeline (Step Functions + Bedrock) that triages incidents in ~6 seconds.

Technical Skills

Cloud (AWS): ECS Fargate, EKS, Lambda, Step Functions, EventBridge, Bedrock, RDS, DynamoDB, S3, CloudFront, API Gateway, VPC, IAM, WAF, Secrets Manager
IaC & CI/CD: Terraform (modular, multi-env, remote state), GitHub Actions (OIDC, multi-stage), CloudFormation
Containers & Orch.: Docker, Kubernetes (EKS + Karpenter)
Observability: LGTM stack (Grafana, Loki, Tempo, Mimir), CloudWatch, X-Ray, Prometheus
Security & FinOps: IAM least-privilege, tfsec, OIDC federation, cost cleanup automation, right-sizing, Fargate/GPU Spot
Languages: Python, Bash, HCL, YAML, SQL; Linux administration

Selected Projects

AI-Assisted SRE Incident Analysis Step Functions · Bedrock · Lambda · Terraform github.com/iEric0228

Event-driven serverless pipeline: EventBridge triggers a Step Functions fan-out of three parallel collectors (metrics, logs, deploy context), analyzed by Amazon Bedrock for root-cause hypotheses.
Advisory-only by design — IAM explicitly denies the analyzer any mutating action; results stored in DynamoDB (90-day TTL) and pushed to Slack/SNS.
~6s end-to-end triage; ARM64 Lambda and Express Step Functions for ~$5/month per 100 incidents.

Enterprise 3-Tier App on ECS Fargate ECS · RDS · LGTM · Terraform

React + Node.js + PostgreSQL (Multi-AZ) on ECS Fargate behind an ALB with full VPC isolation; refactored a 1,200-line monolith into 9 focused services.
Full LGTM observability stack, Secrets Manager, WAF, TLS termination; cost-tuned with Fargate Spot and RDS auto-pause.

Aura — EKS GPU Autoscaler EKS · Karpenter · Terraform · GitHub Actions

Ephemeral EKS clusters that deploy, run a batch AI workload, collect results, and self-destruct — Karpenter scales GPU NodePools to zero to eliminate idle cost.
OIDC identity federation: GitHub Actions as trusted IdP, zero static AWS keys.

FinOps Zombie Hunter Lambda · EventBridge · Terraform · tfsec

Scheduled Lambda that hunts orphaned resources (EBS, NAT Gateways, RDS, EIPs) across all enabled regions; flagged ~$230/month of waste in a test account.
Dry-run by default with a report-only vs. delete safety model; tfsec + flake8 gate the CI pipeline.

Cloud Resume (ericchiu.page) S3 · CloudFront · Lambda · DynamoDB · Terraform

Serverless resume site with a live visitor counter (Python Lambda + DynamoDB behind API Gateway); full IaC and OIDC-based CI/CD to S3 + CloudFront.

Operations Leadership

Shift Leader — Teazzi 2021 – 2024

Ran live operations for a high-volume location — real-time triage of equipment failures, supply shortages, and customer escalations under rush-hour load.
Built the closing/shift-handoff checklist that cut transition errors; directed a 4–6 person team through peak throughput.

Assistant Manager — OneZo 2018 – 2021

On-site decision-maker in the manager's absence; supervised 6–10 staff with scheduling, onboarding, and SOP training.
Partnered with ownership on inventory, staffing, and quality control against tight timelines.
