IT infrastructure & network engineering · Katy, TX

From an empty building to a documented handover.

AdvancedEC delivers infrastructure projects end to end — a new site built from nothing, a platform migration, an 802.1X and segmentation rollout, a virtualization estate, or the one project that stalled and needs finishing. Network, server, and cloud treated as a single system rather than three separate vendors, and handed over documented when it is done.

What you are actually buying

The engineer, not an account team

The person who scopes the work is the person who does it. No bench assignment, no project manager relaying questions, and no discovering on day one that the senior engineer from the pitch is committed to another account.

No hardware on the invoice

AdvancedEC resells nothing. That means an assessment here can legitimately conclude that your existing switches are fine and you should spend the budget elsewhere — a finding a reseller cannot reach profitably.

Both stacks, no favourite

Aruba and Cisco, wired, wireless, and access control on each. Nothing in the recommendation depends on which vendor wins, because there is no partner tier riding on the answer.

01 — Engagements The work

Scoped projects with a beginning and an end — greenfield builds, migrations, and the work that stalled halfway. Whole-stack when that is what it takes: the network, the servers under it, and the cloud services above. Not a support contract, and not a body in a seat.

Build

New sites & ground-up builds

An empty building to a working floor — cabling standards, wired and wireless design, addressing and segmentation, servers and identity, written down so the tenth site matches the first.

  • Wireless surveys and AP placement
  • Switching, uplinks, and campus fabric
  • Addressing, VLAN, and segmentation models
Migration

Platform migration & refresh

Aruba to Cisco, Cisco to Aruba, or a generational refresh in place. Planned cutovers with a tested fallback, staged by site rather than attempted in one night.

  • Controller and management-plane transitions
  • Switch refresh and configuration conversion
  • Phased cutover and rollback planning
Access

Secure access & NAC

802.1X, certificates, and segmentation from policy model through enforcement. Most rollouts stall in the same place — going from monitor mode to enforcement without locking out the building — and that phase is the work.

  • 802.1X wired and wireless, EAP-TLS and PEAP
  • Certificate-based auth, PKI and auto-enrolment
  • MPSK / iPSK for headless and IoT devices
  • Active Directory and Entra ID as identity source
  • Dynamic segmentation and colourless ports
  • Monitor mode to enforcement, with an exception path
Assessment

Assessment & standards

What is actually deployed versus what the documentation claims, where the two drifted, and what it will cost to close the gap. Delivered as a written report you keep either way.

  • Configuration and standards audit
  • Documentation and diagram rebuild
  • Ranked remediation plan with costs
Infrastructure

Server & virtualization

VMware and Hyper-V estates, Windows Server and Active Directory, DNS and DHCP — designed and consolidated alongside the network rather than as someone else's separate project.

  • vSphere and Hyper-V design and consolidation
  • Active Directory and DNS/DHCP structure
  • Microsoft 365 and hybrid identity
Cloud

Cloud infrastructure & identity

Azure and Microsoft 365 as infrastructure rather than a subscription — tenant design, hybrid identity, and workloads moved off-premises with the network path and the access model designed together.

  • Azure IaaS, virtual networking, site-to-site
  • Microsoft 365 tenant design and migration
  • Entra ID, hybrid identity, conditional access
  • Cloud-managed network control planes
AI readiness

AI infrastructure readiness

AI projects arrive assuming the infrastructure underneath them is already adequate. It usually is not. This is the unglamorous part — establishing what a GPU cluster or an inference workload will actually demand of your network, storage, and power, before the hardware is on a purchase order.

  • GPU host connectivity and east-west fabric
  • Storage throughput and data-path design
  • Power, cooling, and rack capacity review
  • Segmentation and data-residency constraints
Automation

Automation & tooling

Configuration generation, source-of-truth reconciliation, and reporting built against your systems — so the repetitive part of the last project doesn't have to be repeated by hand on the next one.

  • Config generation from your standards
  • IPAM, CMDB, and monitoring reconciliation
  • Custom integration against vendor APIs

02 — Experience Platform depth

Enterprise campus stacks carried end to end, the small-business platforms that fit a smaller building and budget, and the server, virtualization, and cloud infrastructure underneath both. Not certification-deep — deployment-deep. The distinction matters when the window is four hours and the fallback has to actually work.

03 — Selected work Engagements

Client names, locations, and identifying details are withheld under confidentiality. The projects below are described by their shape rather than their logos.

Enterprise

Large multi-facility campus estate

Network automation console

Designed and built an internal platform that generates switch and access-point configuration from documented standards, then reconciles it against the systems that are supposed to agree — IPAM, NAC, monitoring, and the CMDB. Replaced a build process that ran on spreadsheets and institutional memory.

Aruba CentralClearPassBlueCatClarotyServiceNow
Portability

Second estate, different vendor stack

Multi-vendor portability

Reworked that platform so it is not welded to one organization's vendor choices. Each capability — network management, access control, IPAM — sits behind a driver interface, so a site on one vendor stack runs the same product as a site on another, with the inapplicable pieces switched off rather than half-built.

Catalyst CenterCisco ISEInfobloxCapability model
IPAM migration

Enterprise DDI transition

Address-space reconciliation

Built the tooling to migrate between IPAM platforms without trusting either one blindly — reconciling fixed leases against reservations by IP address, enriching each record with its device profile, and producing the exception list of what genuinely had to be resolved by hand.

InfobloxBlueCatReconciliation
Restricted environment

Network with no outbound connectivity

Air-gapped deployment

Packaged the platform to install into an environment with no outbound connectivity at all — delivered by copied bundle rather than by URL, with signed updates, automatic snapshots, and rollback. No agent phoning home and no standing inbound access into the protected network.

04 — Approach How it runs

Three stages, whether the engagement ends in a design document, a built-out site, or a completed migration.

STAGE 01

Assess

What is actually deployed, what the standards say, and where the two have drifted apart. You get written findings — ranked, costed, and yours regardless of whether the project continues.

STAGE 02

Execute

Design and implementation against a fixed scope. Build order, migration path, rollback, and maintenance windows agreed before anything is touched — not improvised at 2 a.m.

STAGE 03

Hand over

Documentation, diagrams, and any automation built along the way, transferred to your team. The measure of success is that you don't need to call me about it again.

05 — Contact Start here

Tell me what the project is.

A migration you would rather not run alone, a NAC rollout that stalled in monitor mode, or a network nobody has documented in six years. Based in Katy, working across Cypress, Sugar Land, Houston, and The Woodlands — and remotely where the work allows. First conversation costs nothing.
