About David Henry

Looking for a developer who doesn't just write code, but understands your business logic?

With over 14 years of experience, I help companies in Spain and Peru transform complex infrastructures into efficient, scalable, and secure web solutions. My profile combines the agility of the WordPress/WooCommerce ecosystem with the robustness of Laravel and Oracle enterprise architectures.

How can I add value to your project?


WordPress & WooCommerce Ecosystem:I don't install templates; I build tools. Specialist in custom plugins, deep Child Theme customization, and critical performance optimization (Core Web Vitals).

Laravel & Node.js Development:Building robust applications, CRMs, and REST API services designed to scale and support intensive workflows.

Data Architecture & Cloud:Expert in Oracle PL/SQL and managing large-volume databases. Experience in deployment and automation on Google Cloud Platform (GCP) to ensure high availability and security (Snapshots/Versioning).

Recent success stories:


Insurance Sector:Backend implementation for reinsurance management, connecting Node.js with complex calculation systems and data transformation in Oracle PL/SQL.

E-commerce & Legal Tech:Creation of a mandatory packaging reporting system for WooCommerce with subscription plan logic.

Cloud Migration:Comprehensive optimization and migration of tourism portals to GCP, improving load speed and conversion rates.

My Technology Stack:


*Backend:PHP (Laravel), Node.js, Oracle PL/SQL, SQL Server.

*Frontend:Angular, JavaScript (ES6+), HTML5/CSS3.

*CMS & Cloud:WordPress Expert, WooCommerce, Google Cloud, Git/GitHub.


Shall we talk? If you're looking for a technological partner who guarantees the continuity and growth of your platform, I'll be happy to analyze your project.
