Hi, I'm Jose 👋

Head of Platform & Solutions Architect | 25 years leading technology adoption

🎯 What I Do

I help companies modernize legacy systems and build scalable platforms with clear ROI and pragmatic architecture decisions.

Track record: 2001 online insurance pioneer (Spain) → 2025 platform engineering for critical 24x7 systems

🚀 Highlights

Recent Projects

• 🛠️ ai-diagrams-toolkit: Mermaid templates + semantic colors + AI integration for professional diagrams
• 💰 €98k savings: Google Workspace → Open Source stack (350 users, 9 tools) - Validated OpenDesk EU 2025
• 🎯 99.5% uptime: Critical aerial emergency systems (24x7, 5-person team)
• 📊 60-70% incident reduction: Systematic analysis + pragmatic improvements

Transformations Timeline

• 2001: 🏆 Pioneer online insurance Spain (FIRST quoter, before Rastreator) + Microsoft case study
• 2008: 🔓 Open source enterprise (Symfony 1.2 + ExtJS 2.2, cutting edge)
• 2015: ⚙️ Early DevOps adoption Spain (Ansible + automation, before mainstream)
• 2022: 👥 Organizational transformation (Team 0→4.5 FTE, Google→OSS)
• 2024: 🚁 Critical platform engineering (Avincis aerial emergencies, 99.5% uptime)

💡 My Approach

Pragmatism over hype:

• ✅ €190-280k documented savings by saying NO to overengineering
• ✅ Docker Swarm when K8s is overkill (€100-150k saved)
• ✅ Right-sizing architecture to team capacity (not resume-driven development)

Hands-on architect:

• ✅ Design on whiteboard AND debug at 3am
• ✅ Code reviews after 38 years programming
• ✅ Matrix org coordination (20-24 people across 4 vendor teams)

Testing-first:

• ✅ DDD/Hexagonal architectures
• ✅ CI/CD quality gates
• ✅ TDD advocacy
• ✅ With AI adoption, testing is more critical than ever
