Senior Linux/DevOps Engineer & AI Automation Specialist Senior Linux/DevOps Engineer and AI Automation Specialist with 15+ years of experience designing, building, and scaling cloud-native infrastructure and intelligent workflow systems. My background combines deep cloud architecture expertise (AWS-focused) with hands-on experience building AI-powered automation using n8n, LLM APIs (OpenAI, OpenRouter), vector databases, and secure cloud environments. Most recently, I've led DevOps and cloud-security engineering for a U.S.-based healthcare SaaS platform (physician scheduling) operating under HIPAA and SOC 2. The work spans secure AWS operations, fleet patch management across mixed Windows/Linux estates, EKS lifecycle management, and building the security tooling and audit evidence that underpin a SOC 2 program — turning compliance requirements into reliable, automated, production-grade controls. Cloud & Infrastructure Expertise Over 12 years of AWS experience designing secure, scalable, production-grade environments across healthcare, banking, and enterprise sectors. AWS Services EC2, RDS, EKS, VPC, IAM, S3, CloudFront, Route53, Elastic Beanstalk, SQS, EFS, ElastiCache, Redshift Systems Manager (SSM), GuardDuty, Security Hub, AWS Config, Inspector, CloudTrail Infrastructure as Code Terraform & CloudFormation — multi-account secure environments ADR-driven design and Strangler Fig migration strategy Containers & Orchestration Kubernetes (EKS), Docker, ECS, Docker Swarm EKS cluster lifecycle management — Kubernetes version upgrades across dev/staging/prod CI/CD Jenkins, GitLab CI/CD, CircleCI, CodePipeline, ArgoCD GitHub Actions with ARC (Actions Runner Controller), Azure DevOps self-hosted agents GitOps & Kubernetes Configuration Management ArgoCD (declarative continuous delivery, app-of-apps pattern, multi-cluster sync), Kustomize (base/overlay structuring, environment promotion, patch management), Helm (chart authoring, versioning, values management across environments). GitOps workflows with full audit trail and rollback capabilities. Designed and operated production GitOps pipelines for EKS clusters in regulated environments. High Availability HAProxy, Nginx, Load Balancers, Heartbeat Led infrastructure teams in banking environments and designed highly available Kubernetes production systems for U.S.-based healthcare companies. Security, Compliance & Governance (SOC 2 / HIPAA) Hands-on implementation and continuous evidence for compliance programs in regulated healthcare environments. SOC 2 control implementation and evidence collection across multiple AWS accounts (logical access, audit logging, encryption, change management, patch management) HIPAA-aware architecture: least-privilege IAM, encryption at rest and in transit, end-to-end audit trails, and EDR coverage across the fleet AWS-native security stack: GuardDuty, Security Hub, AWS Config, Inspector, CloudTrail Prowler (soc2_aws framework) and Vanta (GRC) for continuous control mapping and posture monitoring AWS IAM Identity Center (SSO): MFA enforcement, permission sets, SAML federation, CC6.1 remediation EDR migration: CrowdStrike Falcon → Microsoft Defender, with continuity of endpoint protection enforced as a hard gate Immutable S3 evidence stores, fleet-wide backup-policy review, and EBS encryption rollout for compliance Multi-account delegated-administrator security posture (Security Hub / Config) Architecture Decision Records (ADRs) for traceable, auditable change governance Windows Server & Mixed-Fleet Operations Operated a ~70-instance EC2 fleet (Windows Server + Linux) plus ~35 EKS worker nodes AWS Systems Manager: Patch Manager (AWS-RunPatchBaseline), Session Manager, Fleet Manager, Run Command Established a formal monthly patch cadence; raised Windows patch compliance from a low baseline to ~84% Windows Server lifecycle / EOL planning: Server 2016 → 2022 upgrade and decommission roadmaps aligned to patch-management policy KB-level risk triage (e.g., hostname-length reboot risks on domain members) with documented remediation Active Directory domain controllers and SQL Server hosts (HA production pairs, RDS member servers, performance tuning) Safe-patch workflow with pre-patch EBS snapshots and post-reboot service validation Observability & Monitoring Datadog, New Relic, Zabbix — agent consolidation and cost optimization across EKS and production hosts Networking & Secure Access Tailscale (subnet routers, zero-trust access), VPC design, Route53, Load Balancers AI Automation & Workflow Engineering Beyond infrastructure, I specialize in AI-powered workflow automation: n8n workflow design (cloud & self-hosted) LLM integration (OpenAI, OpenRouter, local models) RAG architectures (Qdrant, vector search, embeddings) AI-driven CRM automation Intelligent document processing Automated client intake & communication systems Secure AI pipelines for regulated industries I design workflows that are secure, easy to maintain, scalable
