Specializes in building modern, high-performance Rails 7+ web applications. Expertise includes optimizing Active Record queries (N+1 prevention), implementing partial page updates with Hotwire (Turbo Frames/Streams), handling real-time communication via Action Cable, and managing background jobs using Sidekiq. The process includes rigorous RSpec testing and database schema management.

Detects TypeScript/JavaScript circular imports, visualizes dependency cycles with tools like madge, and offers strategies (shared interfaces, DI, dynamic/type-only imports, barrel restructuring) plus CI checks and ESLint rules for ongoing prevention.

This comprehensive guide outlines the core principles for developing immersive Virtual and Augmented Reality (VR/AR) applications. It covers critical aspects such as platform selection (Quest, ARKit, ARCore), mandatory performance metrics (FPS, frame budget), user comfort techniques (motion sickness prevention), and best practices for spatial interaction and world design. Essential reading for engineers building next-generation spatial computing experiences.

This skill enables AI-assisted debugging and comprehensive error analysis within the development environment. It utilizes Cascade to analyze complex error messages, stack traces, and surrounding code context to identify root causes. Use it when troubleshooting code or encountering runtime errors to receive detailed fix recommendations and prevention strategies.

A comprehensive protocol defining communication rules and orchestration patterns for multi-agent C-suite teams. It structures complex cross-functional analyses, simulates board meetings, and enforces hard rules—such as depth limits and loop prevention—to ensure consistent, verifiable, and non-circular business insights.

This skill provides deep analytical insights into aggregated family health data. It assesses genetic predisposition, identifies patterns of familial diseases, calculates weighted risk scores based on historical data, and generates personalized, actionable prevention recommendations. Ideal for generating comprehensive family health reports and trend analysis.

Design and optimize cancel flows, exit surveys, save offers, and dunning sequences to stop voluntary and involuntary churn and recover failed-payment revenue for SaaS teams focused on retention.

This skill provides comprehensive strategies and technical blueprints for monetizing digital products, especially SaaS platforms. It covers everything from defining advanced pricing models (freemium, value-based pricing) and optimizing revenue flows (LTV/CAC, churn prevention) to practical Stripe integrations. Use it when you need to set up subscription plans, process webhooks, or implement automated billing cycles for your software.

Guides implementing cloud data loss prevention across AWS Macie, Azure Information Protection, and Google Cloud DLP with discovery jobs, classification, scanning, and de-identification so sensitive data in storage, databases, and pipelines stays protected and compliant.

Guide to deploy Suricata as an inline IPS, set up NFQUEUE or AF_PACKET modes, configure Emerging Threats rules, tune threading/stream settings, and integrate logging for real-time network threat blocking.

Deploy and configure Palo Alto Networks next-generation firewall with App-ID, User-ID, SSL decryption, and threat prevention profiles to secure enterprise networks, covering system setup, zone architecture, and policy workflows for compliance and assessments.

Hardens process historian servers (OSIsoft PI, Honeywell PHD, GE Proficy, AVEVA Historian) in OT networks by covering Purdue-tier segmentation, secure interfaces, DMZ data replication, injection prevention, and integrity checks for safety, compliance, and optimization scenarios.
