## Compliance & Standards

### Section 508 / WCAG 2.1 AA

- [US government websites](/industries/government) built to federal accessibility standards
- Screen reader compatibility testing
- Keyboard navigation support
- Color contrast ratios meeting federal requirements
- Alternative text for all media
- Accessible forms, tables, and interactive elements
- Automated accessibility testing in CI pipeline

### Pharmaceutical Regulatory Compliance

- [Pharmaceutical brands](/industries/pharmaceutical) served over multi-year engagements
- HCP (healthcare professional) and patient content separation
- Regulatory content review workflow support
- Medical/legal/regulatory (MLR) approved content implementation
- Quarterly update cycles aligned with regulatory timelines

## Architecture & Methodology

### Clean Architecture (DDD)

Our enterprise platform uses Domain-Driven Design with Clean Architecture. Four-layer separation:
- Domain layer (zero external dependencies)
- Application layer (CQRS, use cases)
- Infrastructure layer (data access, external services)
- API layer (ASP.NET Core Web API)

This architecture has supported 8+ years of changes without a major rewrite.

### Async-First Operations

- Written requirements for every project
- Basecamp, Productive.io for project management
- Loom for async video communication
- Fewer than 5 meetings per year on our [longest partnership](/partners/anchorwave)
- Nepal is 9:45 ahead of US Eastern in summer and 10:45 in winter, so your day's handoff is done by your morning

### WordPress at System Level

Our block theme architecture is a deployment system:
- Core theme with shared accessibility and performance standards
- Child themes for per-client customization
- Block patterns library for content layouts
- Visual regression testing (Playwright) catches visual breaks before deployment
- Sandbox environments for testing
- Licensing server for commercial distribution
- MCP server that lets an AI agent manage themes

### Content Operations at Scale

- 30+ distinct brand voice profiles (one written voice guide per site)
- Three-layer prompt system (base rules, domain voice, article-specific)
- Three-pass quality check: structure and SEO, voice, facts
- Banned words list (100+ items)
- 7,500 to 20,000 words per site per month
- Formal trainee programs (3 batches completed)

## What We Do Not Do

- **Low-level systems programming.** We build applications, not operating systems or drivers.
- **ML model training.** We integrate AI APIs into agents, chatbots and content tools. We do not train models from scratch.
- **Hardware design.** We build IoT software, not hardware.
