I'm a career, presales-focused solutions architect / systems engineer focused on building practical solutions that solve real problems. I am most definitely not a developer, but rather an infrastructure solutions architect, as well as being an avid hobbyist and a technologist - I enjoy working with Python, containerization, and building tools that make infrastructure management and development workflows more fun and efficient. Some of the projects highlighted below are:

• 🔧 python-based CLI tools for extending infrastructure management
• 🔧 Building production-ready Flask applications with comprehensive test coverage
• 🐳 Containerizing everything with Docker multi-stage builds
• ☁️ Automating AWS Lambda development and VMware Cloud workflows
• 🏠 Running a Raspberry Pi k3s cluster with self-hosted services
• 🔐 Managing secrets securely with 1Password CLI

• Python (3.9-3.12) - Flask, SQLAlchemy, Pandas, NumPy, Pydantic
• SQL - PostgreSQL, database design and optimization
• Frontend - HTML/CSS, Jinja2 templates
• Shell - Bash/Zsh scripting for automation

• Containerization - Docker, Docker Compose, multi-stage builds
• Cloud Platforms - AWS Lambda, VMware Cloud on AWS
• Orchestration - Kubernetes (k3s)
• CI/CD - GitHub Actions, automated deployments
• Security - Docker Scout, Let's Encrypt/SSL management

• VMware Datacenter Infrastructure - VMware ESXi / vSphere / VMware Cloud Foundation, VMware vSAN, VMC on AWS
• Nutanix Datacenter Infrastructure - Nutanix Cloud Infrastructure, Nutanix Unified Storage, Nutanix Cloud Clusters
• Web Servers - nginx (reverse proxy, load balancing)
• Databases - PostgreSQL, database migrations
• Version Control - Git, GitHub
• Testing - pytest, pytest-flask, testcontainers
• Monitoring - Datadog integration
• Hardware - Raspberry Pi cluster with k3s

• View all my badges on Credly- Nutanix, VMware, Dell, EMC, Cisco
• View all my Microsoft certifications- expired - MCP, MCT, MCSAx2, MCSEx2
• Expired Citrix Certifications - CCAx3, CCSPx2, CCEA, CCIA, CCI
• Photographic evidence for all the old stuff!
