About — readme.txt
Self-taught, into computers since I can remember. I work across the dev/ops boundary — writing the infrastructure code one day, debugging what broke in production the next. Hands-on experience spans cloud infrastructure, container orchestration, CI/CD pipelines, and system administration, from bare metal to multi-cloud.

Experience — career.log
- Develop and maintain infrastructure and DevOps pipelines across a portfolio of concurrent client projects in regulated industries (healthtech, medical devices), on AWS, Azure, and dedicated government cloud
- Build CI/CD pipelines for medical device software (SaMD) on iOS and Android that generate the compliance evidence auditors ask for — SAST, DAST, SBOM, SCA, and vulnerability scan reports — against ISO 27001, ISO 13485, IEC 62304, FDA 21 CFR Part 11, GDPR, and NIS2
- Lead cloud migrations and infrastructure modernization for clients moving off legacy setups, codifying environments with Terraform and CloudFormation and configuration with Ansible
- Design automated data pipelines, including AI-driven aggregation of external data sources into unified client portals
- Introduce monitoring and observability so clients get real visibility into infrastructure health and compliance posture
- Deliver independent cloud architecture, site reliability, and DevOps automation consulting for diverse client engagements
- Design and implement tailored Infrastructure as Code (IaC), zero-downtime deployment pipelines, and scalable cloud operating models
- Managed high-density cloud infrastructure for HealthSuite Digital Platform (HSDP), maintaining thousands of regulated AWS multi-tenant environments supporting global healthcare solutions
- Automated provisioning of scalable cloud foundations (VPC, EC2, RDS, IAM, S3) using Terraform, AWS CloudFormation, and custom AWS CLI automation scripts
- Standardized observability and compliance across all workloads using Amazon CloudWatch, CloudTrail, and New Relic dashboards; streamlined release cadences using Jenkins, Git, and AWS CodePipeline
- Maintained Software as a Medical Device (SaMD) platforms under strict Quality Management System (QMS) frameworks, ensuring full alignment with medical device regulatory standards (ISO 13485 / FDA)
- Authored end-to-end Terraform configurations across core AWS services (VPC, EC2 Auto Scaling, RDS, Lambda, CloudFront, Route 53, AWS Backup)
- Established and administered robust CI/CD and artifact pipelines using Jenkins, SonarQube, Sonatype Nexus, Packer, Ansible, and OpenVPN across SDLC and PLC environments
- Architected multi-cloud and hybrid environments spanning AWS, Azure, DigitalOcean, Hetzner, and on-premises OpenStack clusters
- Decoupled legacy monolithic applications (PHP, .NET, Node.js) into containerized microservices managed via Docker and Helm on Kubernetes, improving deployment frequency and developer productivity
- Standardized configuration management with Terraform and Ansible, driving automated rollouts via GitLab CI with persistent distributed runner caches
- Deployed centralized system logging and application performance monitoring using Zabbix and Sentry
- Delivered a turnkey, highly available web hosting architecture on an OpenStack private cloud under a fixed delivery window
- Automated end-to-end environment provisioning and application deployment using Terraform and Ansible
- Deployed and administered new containerized platform infrastructure leveraging Docker, Rancher Orchestrator, Linux, and Ansible across bare-metal, VM, and public cloud (AWS/Azure) environments
- Maintained high-availability production environments using HAProxy, Keepalived, Nginx, PHP-FPM, MySQL/MariaDB, and Nagios across mixed Linux distributions (RHEL, CentOS, Debian, Ubuntu)
- Successfully executed zero-loss customer data migrations from legacy platforms into modern containerized clusters
- Administered Windows Active Directory enterprise domain and directed the infrastructure migration from physical servers to a virtualized hypervisor setup
- Maintained enterprise networking hardware (routers, managed switches) across 19 branch locations to ensure continuous uptime and operational connectivity
- Developed custom internal PHP tools integrated with CRM/ERP systems and scripted routine administrative workflows using PowerShell
- Delivered tier-2/3 technical diagnostics, workstation/network repairs, and system maintenance across client locations and remote connections
- Implemented, configured, and supported enterprise CRM, WMS, and ERP installations, complemented by CMS web development (WordPress, Joomla)
