# Adrian Golub — Senior Backend Engineer · Agentic AI Systems · PHP/Drupal

> Senior PHP/Drupal engineer with 11+ years in business platforms and backend systems. I design agentic software-delivery workflows that turn requirements into reviewed code through scoped autonomy, executable checks and evidence. I built GERIAS with an autonomous development loop and distilled the method into AI_BOOTSTRAP.md for reuse across projects.

## Key Architectural & Agentic Realizations
- **GERIAS + AI_BOOTSTRAP.md:** Auto-service SaaS built with an autonomous agentic development loop. Method distilled into `AI_BOOTSTRAP.md`: ticket-driven execution, isolated work, layered verification, pull requests, provenance tagging (PROVED, ASSUMED, UNVERIFIABLE-HERE), and context-specific autonomy ceilings.
- **Agentic Delivery System:** Requirements → Ticket → Branch → Implementation → Verification (test gates / red-green) → PR → Review / Merge. On personal projects (e.g. GERIAS), merge can be automated within defined limits; on client enterprise projects (e.g. Brand USA, MedLife), workflow strictly stops at PR for human review.
- **Enterprise Drupal Engineering:** Upgrades to Drupal 11 & PHP 8.3 (DC Courts), Apache Solr edismax search tuning, phrase boosting, PDF document indexing, custom REST APIs.
- **Identity & CRM Synchronization:** Salesforce-to-Drupal contact synchronization, Simple OAuth, OAuth 2.0 PKCE, and state-aware account activation rules (Brand USA PSP).
- **International Consumer Platforms:** Reusable Drupal multi-market gamification module across ~15 Nescafé markets; maintenance across Purina ONE, Gourmet, and MedLife Marketplace.
- **Business Systems History:** 8-year production lifecycle on proprietary CRM (AiSuccess, 2013–2021) and high-volume operations (WO Online Market, 2015–2021).
