Escalation grade engineering.

Windows 11, macOS and Linux endpoints. Sync failures, boot and profile corruption, driver conflicts and performance regressions — traced through ProcMon, Event Viewer and ODL rather than guessed at.

• Sync engine and file-state failures
• Profile and roaming corruption
• Boot, update and rollback faults
• Performance and memory-leak analysis

iOS and Android application faults down to the individual API call. Account state, token lifecycle, offline caches and data-sync behaviour, verified against captured traffic.

• Auth and token refresh loops
• Offline cache and data-sync defects
• Photo, metadata and media handling
• HAR and proxy traffic analysis

Windows Server and Linux estates, Active Directory, DFS, storage tiers and backup engineering. Built to survive an audit as well as an outage.

• Active Directory and replication health
• File services, DFS and permissions
• Backup, restore and retention design
• Capacity and storage tier planning

Docker, Kubernetes and Kafka — deployment, tuning and live incident response. From a crash-looping pod at 2am to a consumer group that silently stopped committing.

• Cluster and workload troubleshooting
• Kafka consumer lag and rebalance storms
• Helm release and rollout strategy
• Resource limits and autoscaling tuning

Deletion cascades, sync-driven data loss and retention questions. Recovery windows vary by platform, so the earlier we see it the more we can get back.

• Deletion cascade root cause
• Version history and restore paths
• Retention window assessment
• Preventive policy redesign

Proactive estate monitoring with alerting that means something, plus periodic reviews that catch the fault before your users do.

• Signal-based alerting design
• Trend and regression tracking
• Quarterly estate review
• Capacity forecasting
