    Key Achievements

    Full cross-functional management of the migration of 18 sensitive applications to Azure C3: Coordination in a constrained multi-stakeholder setup.

    Systemic analysis of the setup: understanding decision flows, BUILD/RUN dependencies, network/security/cloud/application interactions, reconstructing the actual delivery, and identifying gray areas (implicit RACI).

    Instance management & project governance: leading Daily/Weekly/Steering Committee meetings, RAIDs consolidation, tracking schedule/dependencies/security prerequisites.

    Risk and organizational impact management: technical debt, service maturity, network dependency, RUN capabilities, pipeline industrialization, governance.

    Analysis of delivery bottlenecks: mapping validation loops (network, ASF, security, encryption, patching, testing), identifying blocking points affecting deadlines, modeling inter-team friction.

    Security & compliance monitoring: managing CipherTrust deployments on CVM (OS compatibility, vendor support), producing waivers, flow matrices, Nessus audit tracking.

    Cloud Ops supervision: Commvault backup monitoring, Dynatrace supervision, Subnets/NSG alignment, validation of operational prerequisites with RUN/infra.

    Critical Lessons Learned & building an optimal trajectory: post-mortem analysis of the setup, defining simplification axes, cloud-native recommendations, and modernization trajectory.
