Skill UI

This skill provides a comprehensive framework for mastering microservices architecture patterns. It covers critical aspects of building robust, distributed systems, including defining service boundaries (Domain-Driven Design), managing inter-service communication, handling distributed data transactions, and implementing various resilience patterns (e.g., circuit breaker, circuit breaker). It is essential for large-scale system decomposition.

Expert mobile developer specializing in React Native, Flutter, and native iOS/Android development. Covers cross-platform development, architecture patterns, performance optimization, data sync, testing, DevOps, security, and app store optimization.

Expert skill for architecting, reviewing, and scaling software systems. Handles architecture, databases, microservices, and infrastructure design to create resilient backend solutions.

A comprehensive guide to integrating privacy protections into software architecture from the ground up. This skill ensures compliance with major global regulations like GDPR, CCPA, and LGPD by implementing core principles such as data minimization, purpose limitation, and default privacy settings. Essential for developers building any application that handles personal user data.

A guide to building robust projections and read models from continuous event streams. This pattern is essential for implementing CQRS read sides, creating materialized views, optimizing query performance, and building complex search indexes in event-sourced architectures. Use it when data needs to be transformed and aggregated from raw events into optimized query structures.

This comprehensive workflow guides the development of modern, scalable full-stack applications using Next.js 14+, React, and TypeScript. It covers all phases, from project setup and component architecture to advanced data fetching (Server Components, React Query), styling with Tailwind CSS, robust testing (E2E via Playwright), and deployment optimization. Ideal for building complex, production-grade web interfaces.

This guide provides comprehensive patterns for designing and implementing secure multi-tenant SaaS applications using shared databases. It covers critical techniques like Row-Level Security (RLS) in PostgreSQL, implementing tenant-aware middleware in TypeScript (Express/Fastify), and enforcing data scoping at the ORM level (Prisma/Drizzle). Learn how to prevent data leakage and manage tenant isolation across shared schemas.

Master enterprise-grade Scala development focusing on functional programming, distributed systems, and big data processing. Expertise includes Apache Pekko, Akka, Spark, ZIO/Cats Effect, and reactive architectures. Covers type-level programming, effect systems, microservices, DDD, performance optimization, and CI/CD deployment.

Reference document for monopoly scale-benchmarks. Provides quick formulas for converting DAU to RPS, storage and bandwidth estimation, known scale limits of common technologies (databases, queues, caching), capacity planning by user scale (1K to 10M DAU), SLO targets, and latency budget guidelines. Useful for system design, capacity planning, and architecture decisions.

This skill provides a comprehensive security hardening checklist for reviewing scoped architectures. It covers network security, authentication, API safety, data protection, secrets management, supply chain dependencies, and incident response protocols. It ensures compliance with standards like GDPR, PCI-DSS, and HIPAA where applicable. Use this to validate controls against evidence-based practices before production deployment.

This workflow covers comprehensive WordPress theme development including architecture, template hierarchy, and custom post types. It supports block editor integration, responsive design, and implements new WordPress 7.0 features like DataViews and Pattern Editing. Suitable for creating custom themes, converting designs, and building child themes with modern admin interfaces.

Generate validated architecture, workflow, sequence, data-flow, ERD, class and timeline diagrams as explorable standalone HTML with themes and export, plus one-page explainers.
