Enterprise IT. Practical infrastructure. Real production responsibility.
Calm under pressure. Clean handovers. Less noise.
Read the full backgroundSelected Work
Infrastructure Operations
Worked across Windows and Linux server estates with a focus on stability, lifecycle discipline, and the operating routines behind core services.
This helped reduce drift, keep ownership clearer, and connect day-to-day server administration with the broader infrastructure platform.
Backup Architecture
Modernized backup storage with immutable object storage while keeping the daily Veeam handling understandable.
The useful result was not just immutability. It was a backup platform that was easier to explain, operate, and test.
SQL Server
Supported SQL Server environments with attention to indexing tradeoffs, workload behavior, failover, maintenance, and production support.
The value came from more predictable behavior and a tighter link between tuning decisions and the way the system is operated.
Virtualization
Worked across virtualization and storage layers with a focus on capacity, reliability, and decisions that support critical workloads.
This helped connect compute, storage, and monitoring decisions instead of treating them as separate problems.
Agentic Development
Use AI coding agents for focused codebase exploration, small implementation tasks, documentation work, and internal tooling while keeping changes reviewable and grounded in the existing system.
The value is faster iteration without losing engineering discipline: clear task boundaries, readable diffs, verification checks, and handovers that a team can still understand after the agent session ends.
Services
The focus is practical work: understand the system, fix the weak spots, and leave something the team can keep running.
Service Focus
Support for stable platform ownership, cleaner day-to-day operations, and fewer avoidable disruptions across core systems.
Technical Focus
Core operating responsibilities across server estates, identity-linked services, lifecycle discipline, and the routines that keep production infrastructure stable.
Service Focus
Virtualization support for production platforms where workload placement, lifecycle discipline, and recovery assumptions need to stay clear.
Technical Focus
Virtual platform operations across VMware and Hyper-V, including host lifecycle, cluster health, placement discipline, and recovery-aware design.
Service Focus
Storage support for production platforms where capacity, performance, redundancy, and lifecycle decisions have to stay operationally clear.
Technical Focus
Storage operations across HPE and NetApp platforms, including array health, lifecycle planning, connectivity, volume layout, and workload-aware capacity.
Service Focus
Internal tools and reporting platforms built around operational data, clear dashboards, and practical AI assistance for recurring work.
Technical Focus
Tool and reporting platform work across dashboards, operational data flows, automation outputs, and AI-assisted summaries that stay understandable to the team running them.
Service Focus
Backup work built around restore confidence, operational clarity, and recovery paths that still hold up under pressure.
Technical Focus
Protection design centered on repository strategy, restore validation, immutable storage choices, and recovery workflows that stay credible under pressure.
Service Focus
Operational SQL Server support aimed at steadier performance, stronger availability, and fewer surprises in production behaviour.
Technical Focus
Production database operations spanning availability, maintenance, workload stability, monitoring, and tuning decisions that fit real platform behaviour.
Service Focus
Automation support for repetitive administration, clearer operating routines, and less manual effort in recurring change work.
Technical Focus
Repeatable administration through reporting, health checks, provisioning, and scripted workflows that reduce manual effort without hiding operational intent.
Operating Model
Start with what is already there, find the parts that create risk or repeat work, then make targeted changes.
Step 01
Look at the current environment, recurring incidents, weak spots, and the work that consumes too much admin time.
Step 02
Separate urgent noise from the changes that will actually improve stability, recovery, or daily operations.
Step 03
Make targeted changes, document the result, and leave the system easier to operate than before.

Blog
Security and Identity
OpenAI Daybreak, Microsoft MDASH, and the 2026 Verizon DBIR point to the same operational problem: vulnerability discovery is accelerating faster than many patch and validation processes can absorb.

Backup Architecture
Veeam Data Platform v13.1 matters less as another feature release and more as a signal that recovery now has to include identity, security posture, and operational context.
