FEATURED ARCHITECTURECapstone (96/100)

SAMAR

Semantic vision system designed to eliminate 'alarm fatigue' through zero-cloud Edge Computing. Achieved a 0% false-positive rate and an 80% CPU optimization in a real commercial deployment.

The Problem: Traditional CCTV systems trigger hundreds of false positives daily due to passive pixel changes, causing severe alarm fatigue.

The Solution: Built on a zero-cloud Edge Computing architecture. A mathematical filter discards inactivity, triggering the YOLOv8s DNN only upon physical disturbance. Features a Producer-Consumer IPC architecture to bypass the Python GIL, and Server-Sent Events (SSE) for zero-latency telemetry broadcasting at 30 FPS.

Dynamic Provisioning & Orchestration

Engineered a PowerShell orchestrator utilizing dynamic registry-scanning to locate environment variables (AppExecPath). Programmatically provisioned configuration tokens, reducing deployment time from 10 minutes to 30 seconds per endpoint and saving ~20 man-hours.

Zero-Touch Lifecycle Management

Developed deployment wrappers to seamlessly manage software states. Resolved OS-level race conditions by gracefully handling background processes prior to execution, and configured registry states to ensure high availability and continuous operation.

Automated Vulnerability Mitigation

Standardized UWP application deployments across restricted environments via PDQ. Engineered a self-healing routine that dynamically repairs and re-registers corrupt AppxManifests, silently mitigating 3,400+ critical vulnerabilities during peak operational hours.

Zero-Trust Endpoint Hardening

Enforced NTFS ACLs and registry policies (DisallowRun) to globally restrict unauthorized legacy applications. Navigated Windows File System Redirection (Sysnative vs SysWOW64) to enforce strict standard-user compliance globally.

Silent OS Migrations & Network Self-Healing

Automated zero-impact Windows Feature Updates utilizing local caching. Integrated a SYSTEM-level daemon to dynamically restore corporate TCP/IP parameters, proactively resolving DNS failures and decreasing VoIP incident tickets by 95%.
