NEED A SURGICAL TECHNICAL FIX WITHOUT THE OVERHEAD OF A FULL-TIME HIRE?
IS YOUR MULTISITE NETWORK A SLOW CHAOS NO ONE CAN MANAGE?
WORRIED ABOUT DATA BREACHES OR NEED AN URGENT FORENSIC CLEANUP?
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
Installing WordPress is easy; managing critical enterprise infrastructure requires a Software Engineer.
I am Sergio Santamaria, a Senior Solutions Architect with an M.S. in Computer Science (MSCS) and 10+ years of experience. I specialize in solving high-complexity problems where others fail. I don’t just "fix websites"; I engineer resilient systems designed to scale and stay bulletproof.
THE VALUE OF SENIORITY: FROM 5 TO 300 EMPLOYEES
I was the 5th employee at a high-growth startup (GrantSolutions), where I architected the technical foundation that allowed the company to scale to over 300 employees. I know what hyper-growth looks like and how to build systems that survive it.
🤝 TRUST & SECURITY FOR YOUR BUSINESS
Working with a Senior Independent Architect means professional results without the bureaucracy:
Confidentiality (NDA): Fully available to sign legal non-disclosure agreements before accessing your systems.
Data Sovereignty: I follow strict engineering protocols for information handling and privacy.
Executive Communication: Native Spanish and C1 Advanced English for seamless meetings and clear technical reporting.
Total Autonomy: I require zero hand-holding. I analyze, execute, and report. My priority is to save you time.
🚀 ELITE TECHNICAL SPECIALIZATION
Enterprise WP Multisite (WPMS): Architecture of massive networks and expert resolution of complex Domain Mapping and governance issues.
MU-Plugin Engineering: Centralized logic for standardization and extreme performance, eliminating the need for slow, bloated commercial plugins.
Technical SEO & Core Web Vitals: I solve SEO from the server and code level. I fix LCP, CLS, and INP issues to ensure your ROI is never limited by technical debt.
AI-Native Automation: As a Claude Certified Architect, I build custom AI agents and workflows (Python/Railway) to automate complex technical tasks with extreme velocity.
🔐 SECURITY & FORENSIC ANALYSIS (MY CORE)
Forensic Cleanup: In-depth analysis and total removal of malware from files and databases after a breach.
Deep Optimization: Diagnosis of bottlenecks via SQL query auditing, DB index optimization, and New Relic real-time monitoring.
Senior Hardening: Server-level shielding, Nginx/Apache hardening, and custom-built firewalls.

⚠️ INTRODUCTORY RATES: As I am currently building my presence on this platform, my senior rates are temporarily discounted. Take advantage of this elite engineering expertise before rates adjust to market standards.
