Clean Architecture and DDD
Application of Clean Architecture, Domain-Driven Design, CQRS with MediatR and the Strangler pattern for legacy migration without breaking production, including multi-tenant system design.

DevOps and CI/CD
Continuous integration and delivery using GitHub Actions, Azure DevOps, GitLab CI/CD, Docker and OpenTelemetry. Testing with Vitest, xUnit and Playwright E2E.

Security and Compliance
Security practices covering OAuth2, JWT, OWASP and GDPR by design, including AI-assisted audits for security, performance, code quality and technical debt delivered as prioritised action plans.

B2B Automation
Workflow automation using n8n, Make, Zapier and Power Automate, connected to tools such as Airtable, Notion, Google Sheets, LinkedIn, Stripe and webhooks.

Agent-Native Development
Working agent-natively with Claude Code, Cursor and GitHub Copilot agentic mode, with continuous self-checks including lint, tests and smoke runs by agents and human approval at the end.

Technical Leadership and CTO Experience
