Build backends with Node.js, Python, Go (NestJS, FastAPI, Django). Use for REST/GraphQL/gRPC APIs, auth (OAuth, JWT), databases, microservices, security (OWASP), Docker/K8s.

Standard editorial template for any standalone HTML output (reports, RCAs, dashboards, diagrams, slides, recaps). Use EVERY time you generate an HTML file so output follows one consistent house style instead of ad-hoc theming.
Findings-first review agent for code changes. Use when the user asks to review a branch, PR, diff, commit range, or recent changes and wants prioritized, actionable issues instead of implementation work.
Scan and clean stale Claude Code sessions from the shared store at ~/.local/share/claude/projects (used by all .claude / .claude-accountN dirs via symlink). Removes session JSONLs older than N days, orphan subagent dirs, and reports reclaimable space.
Triage ShopHelp XCTest/Swift Testing failures before proposing fixes.
Manage Jira issues through jhelp shell functions (jv, jm, jd, jc, jforward, etc.). Use when the user wants to view, transition, assign, comment on, edit, search, or create Jira work items; when they provide a bare issue number, Jira issue key, or Jira URL; or when the task involves the current git branch ticket.
Create git commits. Use when user says "commit", "commit this", "commit changes", "split commit", "split commit change", "split the changes".

Production-ready backend development with modern technologies, best practices, and proven patterns.
Languages: Node.js/TypeScript (full-stack), Python (data/ML), Go (concurrency), Rust (performance) Frameworks: NestJS, FastAPI, Django, Express, Gin Databases: PostgreSQL (ACID), MongoDB (flexible schema), Redis (caching) APIs: REST (simple), GraphQL (flexible), gRPC (performance)
See: references/backend-technologies.md for detailed comparisons
Core Technologies:
backend-technologies.md - Languages, frameworks, databases, message queues, ORMsbackend-api-design.md - REST, GraphQL, gRPC patterns and best practicesSecurity & Authentication:
backend-security.md - OWASP Top 10 2025, security best practices, input validationbackend-authentication.md - OAuth 2.1, JWT, RBAC, MFA, session managementPerformance & Architecture:
backend-performance.md - Caching, query optimization, load balancing, scalingbackend-architecture.md - Microservices, event-driven, CQRS, saga patternsQuality & Operations:
backend-testing.md - Testing strategies, frameworks, tools, CI/CD testingbackend-code-quality.md - SOLID principles, design patterns, clean codebackend-devops.md - Docker, Kubernetes, deployment strategies, monitoringbackend-debugging.md - Debugging strategies, profiling, logging, production debuggingbackend-mindset.md - Problem-solving, architectural thinking, collaborationSecurity: Argon2id passwords, parameterized queries (98% SQL injection reduction), OAuth 2.1 + PKCE, rate limiting, security headers
Performance: Redis caching (90% DB load reduction), database indexing (30% I/O reduction), CDN (50%+ latency cut), connection pooling
Testing: 70-20-10 pyramid (unit-integration-E2E), Vitest 50% faster than Jest, contract testing for microservices, 83% migrations fail without tests
DevOps: Blue-green/canary deployments, feature flags (90% fewer failures), Kubernetes 84% adoption, Prometheus/Grafana monitoring, OpenTelemetry tracing
