Skill UI

Mastery of advanced system design patterns, including Event Sourcing, CQRS, and Event-Driven Architecture (EDA). This skill covers designing event stores, building read/write projections, orchestrating sagas, and managing eventual consistency. It is ideal for building complex microservices that require guaranteed audit trails, historical state querying (temporal queries), and robust handling of business workflows with compensating actions.

This skill provides patterns and implementation templates for managing complex, long-running business processes across multiple independent services. It focuses on implementing the Saga pattern, ensuring data consistency in microservices architectures. It defines clear states, handles step execution, and crucially includes compensation logic to reliably roll back changes when any part of the workflow fails.

This system provides a structured workflow for tracking security vulnerability exceptions and formally accepting related risks. It mandates documentation of compensating controls, manages required approval chains, and automatically handles expiration based on defined Service Level Agreements (SLAs). Essential for maintaining compliance and visibility into accepted risks, supporting frameworks like PCI DSS, SOC 2, and NIST CSF.

This comprehensive guide details the deployment and configuration of Tofino industrial firewalls to secure critical SCADA and PLC systems. It utilizes Deep Packet Inspection (DPI) capabilities for core OT protocols (Modbus, EtherNet/IP, S7comm), ensuring strict access control and enforcing IEC 62443 zone boundaries. Ideal for segmenting control networks and providing compensating controls for unpatchable legacy equipment.

Provides a structured, risk-based framework for managing patches in Operational Technology (OT) and Industrial Control Systems (ICS). It addresses the critical difference between IT and OT environments, prioritizing safety and availability over immediate remediation. The guide covers risk scoring, vendor compatibility testing, staged deployment, and defining compensating controls for unpatchable assets.

Build a robust, typed API wrapper for Navan's REST endpoints, compensating for the lack of an official SDK. This pattern provides automated OAuth 2.0 token lifecycle management, built-in retry logic (for rate limiting and service downtime), and structured error handling, ensuring reliable, type-safe API interactions in production environments.

This skill helps structure the foundational commercial policies governing discounting off list price. It builds three deterministic tools: a 4D discount matrix builder (considering ARR, term length, payment terms), an exception flow router with compensating commitments, and a policy linter to detect governance gaps. It is designed for Heads of Commercial and RevOps to establish defensible rules of engagement, ensuring margin adherence and preventing discount drift, rather than for approving individual deals.

This skill provides patterns for managing distributed transactions and long-running business processes. It helps coordinate multi-service transactions, implement compensating transactions, and handle failures in distributed systems. Suitable for building order fulfillment and approval workflows in microservices architectures.
