Services

Engagements combine senior infrastructure experience with hands-on implementation. Work is scoped to improve resilience, reduce operational risk, strengthen security boundaries, automate repeatable operations, and keep production systems supportable over time.

Infrastructure Engineering

  • Windows Server and Linux platform deployment and lifecycle management
  • Virtualization architecture (Hyper-V clusters, VMware ESXi, Proxmox)
  • SAN and storage fundamentals with performance hygiene
  • Hybrid and multi-site infrastructure planning

Security & Access Architecture

  • Active Directory, Group Policy, identity, and access architecture
  • MFA and Privileged Access implementation (Delinea / Centrify experience)
  • Juniper SRX firewall design (NAT, site-to-site VPN, remote access VPN)
  • Cisco switching and routing fundamentals
  • Secure network segmentation and boundary enforcement

Edge Network & Resiliency Architecture

  • UniFi Dream Machine Pro (UDM Pro) dual-ISP failover design
  • High-availability WAN design for continuity during ISP outages
  • WireGuard secure tunneling for route optimization and congestion mitigation
  • UniFi Protect surveillance infrastructure (NVR Pro plus multi-camera deployments)
  • Remote monitoring and secure access controls

Reliability & Operations

  • Monitoring and alerting strategy
  • Incident response and root-cause analysis
  • Patch management strategy (HCL BigFix experience)
  • Backup design and restore validation
  • Disaster recovery planning and readiness validation

Automation & Infrastructure as Code

  • Terraform and Ansible provisioning and configuration workflows
  • Python, PowerShell, Bash, and shell-based operational automation
  • Git/GitHub workflows, CI/CD, self-hosted runners, and parallelized validation
  • Repeatable deployment, release, and operational tooling with safeguards and rollback discipline

Applied Systems & Software Engineering

  • Kotlin and Android systems engineering for real-time media and network-aware applications
  • Go backend services for identity, sessions, OAuth integrations, encrypted token storage, SMTP, telemetry, and service proxying
  • Python tooling, APIs, service integrations, and Linux-hosted production services
  • Real-time media transport using RTMP/RTMPS/SRT, HEVC, and multi-link SRTLA networking across Wi-Fi and cellular
  • Secure application delivery, update verification, monitoring, and production reliability engineering

How I Work

Structured delivery with practical execution keeps technical change controlled and outcomes measurable.

Discovery

Evaluate current environment, risk posture, and operational constraints.

Architecture & Planning

Design scalable, supportable infrastructure aligned to business needs.

Implementation

Hands-on execution with rollback planning and change discipline.

Operational Stability

Documentation, monitoring alignment, and knowledge transfer.

Best Fit

Penner.io is a strong fit for organizations that:

  • Experience recurring outages or unstable infrastructure
  • Need secure remote access and identity hardening
  • Are modernizing virtualization or firewall architecture
  • Want repeatable, documented, automation-driven operations
  • Need infrastructure-minded software, API, or service-integration work that can survive production
  • Require senior hands-on execution without enterprise overhead
