Systems Architect & Lead Developer

I am a developer and systems architect with 18+ years of experience building and running high-scale web platforms. My background covers everything from initial MVP design to managing long-term codebase evolution (10+ years on a single flagship project) and ensuring platform availability for high-traffic environments.

Technical Stack & Capabilities

• Drupal Ecosystem: Working with Drupal since the Drupal 5/6 era up to Drupal 11. Deep experience with custom module development, decoupled architectures (REST, JSON:API, GraphQL), multi-site/multi-domain setups, and aggressive performance tuning.
• Backend & Frameworks: Symfony, PHP, PostgreSQL/MySQL, Domain-Driven Design, and implementing strict domain/accounting invariants.
• Infrastructure & Security: Docker, Kubernetes, Terraform, GitLab CI. Experience hardening production systems, setting up deployment workflows, and taking systems through the SOC 2 Type II compliance process.

What I've Built

• Architected and spent 11 years scaling a custom full-stack platform (500k+ LOC) handling CRM, complex automations, and automated billing used by enterprise clients like Mercedes-Benz, EA, and The Linux Foundation.
• Managed a 30+ domain publishing network, maintaining 99.97%+ uptime through targeted performance tuning.
• Led small, cross-functional engineering teams (dev, QA, design) acting as the technical bridge to product stakeholders.
