Alex J. Guillen Consulting, LLC
Senior advisory and program leadership for organizations navigating complex technology transformation — ERP, EPM, HCM, CPQ, payments platforms, AI enablement, and operational turnaround.
About
Alex J. Guillen Consulting brings over 20 years of enterprise technology leadership directly to your organization — without the overhead of a large firm. As both advisor and practitioner, Alex works alongside your executive team to deliver real outcomes.
With senior leadership experience at Fortune 500 companies including NCR Voyix, Hertz, Western Union, and AIR Communities across FinTech, Financial Services, Hospitality, and Real Estate, Alex brings a rare combination of strategic vision and execution rigor — equally comfortable presenting to the board or resolving a program delivery challenge hands-on.
Core areas of practice include enterprise ERP, EPM, HCM, and CPQ modernization, global payments transformation, AI enablement and intelligent automation, and tech debt reduction strategies that free teams to focus on innovation rather than maintenance.
A particular focus is helping organizations scale automation and deploy AI to reduce manual work, augment team productivity, and drive measurable operational outcomes — without disrupting the business in the process.
Based in Southwest Florida and available for engagements nationally and internationally.

Approach
Every engagement is tailored to your organization's specific situation. No templated frameworks. No junior staff doing the actual work. You get direct access to senior experience from day one.
A focused assessment of your current state — technology landscape, program health, vendor performance, and leadership alignment. No fluff; clear findings in 2–4 weeks.
A practical, phased roadmap with sequenced priorities, resource requirements, risk flags, and measurable milestones. Built with your team, not handed down to them.
Embedded advisory or hands-on program leadership. Vendor oversight, stakeholder alignment, executive communication, and weekly cadence management to keep delivery on track.
Knowledge transfer, governance design, and operating model handoff so your organization owns the results — not dependent on the consultant to sustain them.
