Systems Integrator — Solutions Architect

Lindsey M. Jimena

I design, secure, and build the systems that IT teams rely on — from identity and access architecture to the full-stack apps running on top of it.

About

Fixing the problem underneath the problem

I work across managed services and enterprise end-user computing — packaging and deploying applications through Intune, hardening identity and access with Entra ID, and keeping infrastructure running across Azure and Microsoft 365. On the side, I design and build full-stack software from the ground up. I like the parts of the job other people skip: the root cause, the edge case, the runbook nobody wrote yet.

End User Compute - Operations Manager

Willis Towers Watson

Support and secure multiple client tenants across Microsoft 365, Entra ID, Exchange Online, and FortiGate — and build the automation that keeps it maintainable.

IT Operations Manager

Carelon Global Solutions

Directed and coached cross-functional IT teams as a strategic partner to senior leadership — pioneering the Philippine data center build-out and spearheading the pandemic-era WFH rollout of production apps and services.


Owned SLA performance and root-cause resolution across multiple production systems end to end, from incident response through people management — hiring, coaching, and evaluating talent while reporting into IT management and the Senior Leadership Team.


Turned that operational depth into measurable innovation, architecting RPA solutions across SharePoint, Power Apps, Power Automate, and UiPath — including SARSA, an automated asset-tracking and retrieval system, plus automated exit-clearance and compliance-acknowledgment workflows — that saved the business roughly 34,000 hours of manual work in two years.

Concentrix (Formerly Convergys Philippines)

Led global IT initiatives spanning Asia-Pacific (Philippines, India, China), North America, Latin America, and Europe — delivering eight-figure annual savings and bringing onshore infrastructure to the Asia-Pacific region.


Delivered end-to-end enterprise IT support — desktop, server, LAN, telephony, and PBX — across 6,000+ seats at Megamall, Robinsons, and Alabang sites, while owning Active Directory and DHCP administration, Group Policy and SCCM software/patch deployment.


Drove real-time workforce management and reporting for a multi-LOB contact center floor — forecasting staffing 3 months out, monitoring live queue performance, and delivering automation in maintaining service level agreements.
