Senior Solutions Architect

Coretek Services | August 2018 – January 2019

Role Summary

Senior consulting role in enterprise infrastructure, Microsoft 365 migration, identity consolidation, cloud governance, secure file services, PMO automation, and managed-services architecture. This page shows the transition from hands-on engineering leadership into large-scale regulated cloud and security architecture before the Molina / Infosys engagement.

• Migrated a 16,000-user base to Exchange Online in a single Azure AD tenant while consolidating 32 Exchange environments across 27 Active Directory forests after a merger, reducing fragmentation in identity and email operations.
• Preserved user attributes, SIDs, passwords, groups, and profile data during the multi-forest consolidation, treating identity continuity as a cutover requirement rather than a post-migration repair effort for business users and administrators.
• Migrated 10,000 on-premises mailboxes from Exchange 2007/2013 to Exchange Online in seven weeks with less than 2% failure and minimal user impact, converting a high-risk mail migration into a controlled execution pattern.
• Implemented Conditional Access for device and user compliance, strengthening Microsoft 365 identity security while supporting cloud productivity adoption.
• Consolidated user and desktop infrastructure after 19 company acquisitions, preserving user attributes and configurations while standardizing Active Directory, print, DNS, DHCP, VPN, and MPLS patterns.
• Created a Microsoft 365 managed-service program and onboarded a pilot customer with more than 10,000 seats, turning project delivery lessons into a repeatable service offering.
• Architected a Project Online PMO solution with automated onboarding, offboarding, and access provisioning, improving project governance without adding manual administrative overhead.
• Designed the Project Online lifecycle model across production and sandbox instances so resource, team-member, project-manager, portfolio-manager, and administrator access could be provisioned and retired through repeatable governance rather than informal project-team requests.
• Designed custom lifecycle and entitlement patterns across Microsoft 365, Project Online, and merger-consolidation work, translating onboarding, offboarding, license, group, and role-access requirements into repeatable governance controls.
• Designed a secure, highly available file-sharing and virtual-desktop data solution for collaborative media and digital content, balancing performance-to-cost ratio, availability, patching, backup, and disaster-recovery requirements.
• Trained administrators and champions to manage cloud systems after production release, reducing post-cutover dependency on project resources and improving operational ownership.
• Configured secured on-premises SMTP and email relay patterns for applications and devices, preserving business-process continuity while Exchange workloads moved into cloud-managed architectures.
• Designed alternative migration solutions around network and server limitations, eliminating project delays by treating infrastructure constraints as design inputs instead of blockers.
• Guided Project Web App roadmap development, project templatization, and PMO process structure, giving customer organizations a repeatable project-management model beyond the initial Project Online deployment.
• Evaluated internal and client infrastructure and security health, preparing mitigation plans and modernization roadmaps that helped customers sequence cloud, identity, endpoint, and managed-service improvements.
• Positioned sales and solution-architecture teams to support Dynamics 365 offerings, expanding provider capability and strengthening Microsoft partnership value beyond core infrastructure projects.
