I work at the intersection of business requirements, project execution, and operational systems.

My work usually starts with a business or executive need that is still ambiguous, fragmented, or difficult to execute. I turn that need into structured requirements, workflows, implementation decisions, coordinated follow-through, QA/UAT, and release-ready operational systems.

Over 3+ years supporting U.S.-based teams, I’ve worked across implementation, project operations, executive operations, and internal product workflows.

At Broward Flyers & Printing, I led product operations and implementation for a bilingual business visibility giveaway platform, taking it from requirements to production in 5–6 weeks. The platform supported applications, admin review and CRM workflows, applicant and winner portals, fulfillment, communications, bilingual content, and security for a campaign involving 100,000 business cards and up to 100 U.S. businesses.

At Grand Teton Professionals, I own the product requirements and implementation direction for Issues Helper, an internal status-review and critical-issue tracking platform used across recurring cross-functional operations. The structured workflow reduced a 30+ minute document-update process to approximately 5–10 minutes depending on complexity.

My executive-operations work has also helped reduce daily CEO internal-communications handling from roughly six hours to about two, reclaiming approximately 20 hours per week while maintaining cross-functional follow-through.

My strongest areas are requirements gathering, project coordination, workflow design, QA/UAT, release coordination, stakeholder management, process documentation, and executive communications.

I’m most effective in roles where business needs have to become organized execution, not just recommendations.
