1. Software Development

Specializes in generating and managing Zustand stores with selectors and persistence for React state management.

Enables client-side routing in F# Elmish applications using Feliz.Router for page navigation and URL handling.

Guides end-to-end F# full-stack feature development, covering shared types, backend, frontend, and tests across all application layers.

Builds F# frontend applications using Elmish MVU architecture and Feliz for React components, with state management and TailwindCSS styling.

Optimizes spec-driven development workflows to prevent specification drift and eliminate redundant tasks.

Provides data persistence implementation for F# applications using SQLite, Dapper, JSON, or event sourcing with async I/O patterns.

Automates software development workflows including bug fixes, feature implementation, and code refactoring through structured solution packages and knowledge base synchronization.

Specializes in executing test suites, validating mobile UX, ensuring accessibility compliance, and conducting pre-deployment quality assurance checks.

Enables isolated Git worktree workflows for efficient parallel development on multiple branches without context switching.

Evaluates code implementation quality, tracks technical debt via append-only logs, and generates fix queues (prd.json) for specification non-compliance.

Guides developers through creating spec-aligned task lists and setting up execution environments for autonomous implementation loops using ralph-tui.

Provides detailed rules for development implementation phase including execution processes, code standards, consistency audits, and solution package migration.

Integrates Bitcoin Lightning Network payments into applications via Nostr Wallet Connect (NIP-47) and LNURL, enabling transactions, balance checks, and invoice handling.

Automates adding requirement traceability tags (REQ-*) to git commits after refactoring, ensuring bidirectional traceability in TDD cycles.

Provides minimal code implementation to pass failing tests in the Test-Driven Development (TDD) green phase.

Generates executable test code from Gherkin scenarios by implementing step definitions for BDD frameworks.

Guides complete BDD workflow from scenario writing to refactoring using Given/When/Then syntax for test-driven feature development.

Coordinates TDD cycle (RED→GREEN→REFACTOR→COMMIT) for requirement-driven development with REQ-* traceability.

Scans requirements documents for REQ-* keys and verifies corresponding code and test coverage to identify implementation gaps.

Provides advanced TypeScript patterns to enforce type safety and leverage strict mode in development workflows.

Generates Architecture Decision Records (ADRs) to document strategic technical choices, including cloud, language, and architectural patterns, while considering ecosystem constraints.

Ensures all software requirements have corresponding design elements (components, APIs, data models) before code implementation to guarantee design completeness.

Executes integration tests (BDD, API, end-to-end) to validate cross-component system behavior and serve as a pre-deployment quality gate.

Validates test coverage against requirements (REQ-*), calculates per-requirement and overall coverage, and serves as a quality gate for continuous monitoring.
