I help regulated businesses and high-growth technology teams build secure, scalable cloud systems and bring infrastructure costs back in line with actual usage. Cloud architecture across AWS, Azure, and GCP is one half of the practice. The other half is enterprise systems integration: Microsoft Dynamics 365, Salesforce, SAP, and Oracle, including a SAP architecture for a European heavy industrial manufacturer under strict defense-sector compliance, and a full legacy-to-current Oracle migration carried out with training and complete data integrity. Dynamics 365 in particular runs on Azure and Dataverse, so the enterprise systems work and the cloud architecture work are not two separate practices. They inform each other directly, the platform a business runs on and the infrastructure underneath it. Built for production load, not demo load, audit-ready for SOC 2, ISO 27001, and GDPR standards. What I deliver for your business: Cloud Architecture and Migration: planning and migrating existing workloads to high-availability multi-cloud environments. Enterprise Systems Integration: architecting and integrating Dynamics 365, Salesforce, SAP, and Oracle, spanning regulated industrial, manufacturing, and enterprise sectors. Infrastructure as Code: designing clean, modular Terraform configurations for policy-based resource provisioning. Container Orchestration: deploying and managing Kubernetes platform infrastructure, observability, and release pipelines. DevSecOps Hardening: implementing access controls, firewall constraints, and securing CI/CD pipelines through GitHub Actions, GitLab, and Jenkins. Cost Optimization: conducting cloud billing audits, setting up budget alerts, and removing resource waste. Available for project-based work or ongoing infrastructure and systems support. Send over what you are building or what is not working, and you will get a direct technical read back, including an honest answer on whether I am the right fit for it.

I build and run production infrastructure on AWS, GCP, Azure, and on-prem. Most of my work over the last few years has been Kubernetes (EKS, GKE, AKS, and bare metal RKE2 with Rancher) and getting that infrastructure through compliance audits: HIPAA, SOC 2, PCI DSS, and NIST 800-53. 10+ years in DevOps. Top Rated Plus, 100% Job Success. RECENT PROJECTS Built an on-prem RKE2 Kubernetes cluster from scratch for a company preparing for SOC 2 and HIPAA. Rancher for management, Cilium with WireGuard for encrypted pod traffic, GPU nodes for their ML workloads, Longhorn for storage, Velero for backups, ArgoCD for deployments. Enforced SSO through Entra ID on every cluster and SSH access point because their auditors required it. Took a healthcare data platform through HIPAA hardening on AWS. ECS Fargate, Aurora PostgreSQL, private subnets, TLS everywhere, proper secrets handling. Phase one was making it work, phase two was making it pass an audit. Different skill sets, and I do both. Modernized AWS infrastructure for a holding group running four brands. Moved everything to ECS Fargate and Aurora Multi-AZ, set up blue-green deployments, put CloudFront in front. Midway through we found a security breach in their GitHub org and I handled the full remediation across every repo. Fixed a production Aurora MySQL performance problem that had an app timing out during peak hours. Root cause was tmp table spill to disk. Tuned it, added a reader instance, zero downtime. I also do the unglamorous work that keeps things running: CI/CD pipelines (GitHub Actions, GitLab CI, ArgoCD), Terraform for everything, monitoring with Prometheus and Grafana, cost cleanup, VPN and networking issues, and database migrations. INDUSTRIES I KNOW WELL Healthcare (HIPAA is second nature at this point), fintech and payments (PCI DSS), and B2B SaaS. WHAT YOU GET WORKING WITH ME Infrastructure that is written down in code, documented, and reproducible. I answer messages fast, and I will tell you upfront if something is a bad idea or if I am not the right person for it. Send me your project details and current setup. I will give you an honest read on scope and effort before you spend anything.

I'm a Cloud and AI Systems Architect with 15+ years of enterprise experience, including 4 years at Microsoft on the Azure team where I consulted F500 companies like AT&T, Walmart, and Mastercard on AI, cloud adoption, security, and infrastructure at scale. I founded TechVora, a small in-office engineering team based in Houston, TX. We work mainly with clients where security, compliance, and uptime are non-negotiable. All engineers work in-house, we never sub out work, which matters when sensitive data is involved. WHAT MAKES US DIFFERENT I act as the architect on every engagement and don't bill for my time. You get senior-level architecture, design, and oversight built into the cost of your developer. AI & PRODUCTION SYSTEMS Over the last two years we've shifted heavily into production AI - we've shipped four enterprise-grade multi-tenant AI applications across legal, accounting, oil & gas, and media, all involving custom LLM pipelines, RAG, and agents handling real sensitive data at scale. CORE COMPETENCIES - Cloud Architecture & Migration (Azure, AWS, GCP) - AI/LLM Integration — RAG, Agents, Multi-tenant Production Apps - DevSecOps, CI/CD, Infrastructure as Code (Terraform, Bicep) - Data Pipelines, Warehousing & ETL - HIPAA-Compliant Architecture - Monitoring, Observability & Incident Response - M365, Azure Security & Compliance Happy to jump on a quick call - I offer a free strategy session for any new engagement.

What does a Xen cloud Platform specialist do?

A xen cloud platform specialist builds and maintains virtualized server environments using the Xen hypervisor and its associated management toolstack. This role focuses on configuring the control domain, known as dom0, to manage hardware resources for multiple guest virtual machines. The specialist uses the Xen API (XAPI) to automate provisioning, networking, and storage tasks across host pools. They resolve complex issues within the virtualization layer to keep infrastructure stable and responsive.

  • Configure and maintain the Xen control domain (dom0) to allocate CPU, memory, and storage resources to guest virtual machines. The specialist sets up resource pools that allow multiple physical hosts to share workloads and provide high availability for critical services. They apply configuration baselines to ensure consistent behavior across all nodes in the cluster.
  • Manage virtual machine lifecycles by creating, cloning, migrating, and deleting instances through the XAPI management interface. This work includes attaching virtual disks, mapping network interfaces, and installing guest operating systems with appropriate drivers. The specialist verifies that each VM operates correctly within its assigned resource limits and security policies.
  • Design and implement virtual networking and storage paths that connect guest domains to external services and data repositories. They configure bridges, bonds, and VLANs to isolate traffic and optimize bandwidth usage for specific applications. The specialist also integrates shared storage solutions such as NFS or iSCSI to enable live migration and persistent data access for moving workloads.
  • Monitor host and guest performance metrics to identify bottlenecks in processing power, memory allocation, or disk input/output. They use tools like Xen Orchestra or XenCenter to visualize resource usage and set up alerts for abnormal conditions. When issues arise, the specialist analyzes logs from the hypervisor and control domain to diagnose root causes and apply fixes.
  • Develop and maintain documentation for infrastructure configurations, backup procedures, and disaster recovery plans. They create runbooks that guide other team members through common troubleshooting steps and routine maintenance tasks. The specialist also tests backup workflows to confirm that virtual machine states can be restored quickly after a failure event.

How to hire a Xen cloud Platform specialist on Upwork

Step 1: Post a job

Define your virtualization needs clearly to attract qualified candidates. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description. Describe your infrastructure goals in a few sentences and Uma creates a tailored post for this role. You can write a new post, update a saved draft, or reuse an existing template.

  • Specify requirements for managing Xen Project hypervisor environments and XAPI toolstack operations.
  • List tasks such as configuring virtual networking, storage paths, and resource pools for guest domains.
  • Include expectations for troubleshooting control domain issues and maintaining operational documentation.

Step 2: Evaluate candidates

Review portfolios for evidence of hands-on Xen virtualization management. Look for work with Xen Orchestra or XenCenter that demonstrates pool configuration and VM lifecycle control. Uma runs instant video interviews and builds shortlists with side-by-side comparisons to speed up your review.

  • Verify experience provisioning guest VMs and managing hardware emulation via QEMU where required.
  • Check for examples of setting up monitoring alerts and backup workflows for Xen-based systems.
  • Confirm familiarity with Citrix Hypervisor or XCP-ng if your environment uses these specific distributions.

Step 3: Interview your top choices

Discuss technical approaches to virtualization challenges during the interview. Schedule calls within Upwork Messages to receive an immediate transcript and summary after each session. Focus on their problem-solving methods for hypervisor and control plane issues.

  • Ask how they diagnose connectivity failures between guest domains and physical network interfaces.
  • Request examples of optimizing storage performance for high-load virtual machine clusters.
  • Explore their process for updating host systems without disrupting active guest operations.

Step 4: Agree on scope and begin work

Set clear milestones for deliverables like configuration baselines and working VM deployments. Use Upwork Messages and the contract workroom to track progress and share files securely. Identity verification, payment protection, hourly tracking, and project funds protect both parties throughout the engagement.

  • Define specific outputs such as documented network configurations and tested backup procedures.
  • Establish checkpoints for reviewing troubleshooting runbooks and system health reports.
  • Agree on tools for accessing the Xen environment and reporting status updates regularly.
