Most businesses don’t have a technology problem. They have an execution problem.
I’m an Enterprise Program Manager and Technical Transformation Leader who specializes in helping businesses confidently deliver complex technology initiatives that are risky, highly visible, or just plain too important to fail.
Throughout my career spanning 25+ years, I’ve worked with executives, product teams, and engineering organizations to lead enterprise-wide transformations involving ERP, CRM, HRIS, cloud, enterprise integrations, CMS platforms, artificial intelligence, and large-scale data migrations. Whether the goal is modernizing legacy systems, integrating a stack of siloed platforms, or bringing order to a chaotic delivery organization, my focus stays the same: reduce risk and help you execute with confidence.
I don’t believe great programs are won by holding status meetings and managing Excel spreadsheets. Successful programs are built on smart technical decisions, realistic delivery plans, eliminating organizational roadblocks, and keeping the lines of communication open between the business and engineering teams.
On any given day, I’m just as comfortable working with executives on strategy, budgets, and roadmaps as I am digging into the details with product owners, mapping integrations with architects, validating data migrations, configuring Jira workflows, or collaborating directly with engineers to unblock delivery.
I’ve led initiatives ranging from small product teams to global enterprise programs involving multiple vendors, distributed engineering teams, and executive stakeholders.
Some of the initiatives I regularly lead include:
* Enterprise Program & Product Management
* Digital & Business Transformation
* Cloud Strategy, Migration Planning, and Infrastructure Modernization
* ERP, CRM, HRIS, & Contract Lifecycle Management (CLM)
* Enterprise CMS Platforms, Website Migrations, and Digital Experience Platforms
* Enterprise Data Migration and Systems Integration
* Jira, ServiceNow, Agile Delivery, and PMO Process Modernization
* Microsoft 365, Azure, AWS, Identity, Security, and Zero Trust
* Artificial Intelligence Enablement and Business Process Automation
I’ve had the opportunity to work with organizations like Dell, VMware, LG Electronics, Cox Communications, Enovix, along with many high-growth companies navigating major technology transformations.
Some of the platforms and technologies I’ve worked with include Microsoft Dynamics 365, SAP, NetSuite, Salesforce, HubSpot, Workday, Jira, ServiceNow, Azure DevOps, Contentstack, Drupal, WordPress, Evisort, DocuSign CLM, Databricks, AWS, Azure, Microsoft 365, and many more.
I typically get brought into organizations when:
* They need experienced leadership on a large technology initiative.
* Multiple teams or vendors aren’t aligned.
* Requirements are unclear and delivery has stalled.
* Cloud, ERP, CMS, or enterprise platform migrations need clear vision and structure.
* Data migrations or integrations pose significant business risk.
* Leadership needs someone who can understand business objectives and translate them into actionable technical plans.
I don’t come in to add another management layer. I come in to remove the friction that’s keeping your organization from delivering.
If you think I can help with your technology initiatives, I’d love to hear from you.

💡 The talent you hire is the company you are building.
I understand that Leaders at Growth-stage companies don't necessarily wake up saying:
"I need a recruiter."
📈 Instead, they wake up saying:
"I need to launch this product."
"I need to hit revenue goals."
"I need to build an AI team."
"I need a leader who can scale operations."
🤝 By being your go-to recruiter, I want to help you solve Business Problems, not only Hiring Problems.
🔑 My Approach to Hiring:
My clients don't need more candidates. They need confidence that the candidate I send is someone they should actually hire.
🤝 That's why our clients talk about trust, partnership, preparation, communication, and professionalism.
They're not just paying me to fill a role.
They're trusting me to reduce the uncertainty around a hiring decision that could have significant consequences for their business.
☎️ When the hire really matters, contact me.
🎯 My recruiting niche/focus:
➤ Tech (e.g. ML Engineers, Cybersecurity Engineers, SE, Cloud Engineers, etc.)
➤ Sales, Marketing, Product, and GTM roles.
➤ Operations Roles.
➤ Leadership Roles.

I help startups and SMBs build secure, compliant cloud infrastructure
without the cost of a full-time CTO or CISO.
15+ years of cloud architecture and security engineering experience
across companies like Cisco, General Mills, Home Depot, Collins
Aerospace, and other Fortune 500 environments. AWS Certified Solutions
Architect. CISSP in progress.
I specialize in startups operating in regulated environments: CJIS,
FedRAMP, SOC 2, HIPAA, and CMMC. If you need compliance built into
your infrastructure from day one rather than bolted on later, that's
exactly what I do.
How I typically work with startup clients:
Embedded as a fractional technical leader, 10-20 hours per week.
I join your Slack, attend standups when needed, and own your
infrastructure decisions. Minimum 3-month engagement.
Recent example: I serve as fractional Lead DevOps Engineer for a
CJIS-regulated GovTech startup, where I designed and built their
AWS infrastructure, CI/CD pipelines, and compliance controls from
the ground up.
What I do for clients:
- AWS and Azure cloud architecture design and implementation
- Infrastructure as code (Terraform, CloudFormation)
- CI/CD pipeline setup (GitHub Actions, GitLab)
- Security controls and compliance implementation
- Network design (VPC, subnets, security groups, IAM)
- Monitoring, alerting, and incident response
- Architecture decision-making and team mentorship
I also offer one-time engagements:
- Cloud Infrastructure Buildout: I design and build your entire cloud
environment from scratch in 4-8 weeks
- Architecture Review: 2-week deep review of your existing infrastructure
with a prioritized 90-day remediation plan
Tools I work with daily: AWS, Azure, Terraform, Docker, Kubernetes, GitHub
Actions, n8n, Cloudflare, Linux/Ubuntu.
If your startup is building in a space where security and compliance
matter, let's talk. I'm selective about engagements and only take on
work where I can deliver real value.
