## 1. Executive Summary & Editorial Positioning
Senior PHP/Drupal backend engineer with 11+ years in business platforms and backend systems. Adrian designs agentic software-delivery workflows that transform requirements into reviewed code through scoped autonomy, executable checks, and verifiable evidence. He built GERIAS with an autonomous development loop and distilled the methodology into AI_BOOTSTRAP.md for reuse across projects.

His core strengths bridge enterprise PHP/Drupal engineering (Drupal 9/10/11, Symfony components, Apache Solr edismax search tuning, Salesforce API integrations, OAuth2) with modern Agentic AI engineering (context isolation, test gates, provenance tagging, CI/PR autonomy limits).

## 2. Agentic AI & AI-Assisted Engineering

### 2.1 GERIAS & AI_BOOTSTRAP.md (2026)
- **Concept:** An auto-service SaaS and the reusable agentic delivery method developed from building it.
- **Delivery Loop:** Ticket-driven execution → isolated work tree/branch → layered verification → pull request → review/merge.
- **Autonomy Ceilings:** 
  - On personal projects (GERIAS): Merging can be automated within strictly defined boundaries and test coverage gates.
  - On client enterprise projects (e.g. Brand USA, MedLife): Workflow stops strictly at PR generation with mandatory human engineering review and approval.
- **Key Methodologies:**
  - Canonical context injection
  - Isolated roles & worker contexts
  - Provenance tagging: `PROVED`, `ASSUMED`, `UNVERIFIABLE-HERE`
  - Red-proven test gates (tests must demonstrably fail before fix and pass after)
  - Strict distinction between test `FAIL` vs `UNABLE-TO-RUN`
  - Token and step budget limits
  - Transfer proof testing with `tick` and strict autonomy ceilings on client engagements.

### 2.2 AI-Assisted Engineering Initiatives (2024–2025)
- **MedLife Marketplace:** AI-assisted development iterations for search improvements in product taxonomies and related medical products block.
- **Service Map (2025):** Technical prototype using OpenAI API & Drupal for semantic classification and vector embeddings, using a Python/Flask pipeline. Documented precision and memory trade-offs accurately.
- **Social Chatbot Prototype (2024):** PHP chatbot architecture integrated with OpenAI ChatGPT API for Messenger/Instagram customer inquiries (proposed architecture and implementation prototype).

### 2.3 Methods & Systems
- **BDSE-Agent-v1:** A structured Business Discovery and System Engineering methodology covering AS-IS/TO-BE analysis, root-cause identification, implementation trade-offs, functional requirements, KPIs, and MVP scoping.
- **Multi-Project Orchestrator:** In progress architectural exploration for orchestrating multiple agentic delivery contexts.
