Freelancer profile translated to English.

Description

Hello! I'm David Hernández, a developer with dual qualifications in Web Application Development (DAW) and Multiplatform Development (DAM).

My greatest differentiating value is that I can handle the integral development of your project (End-to-End): from server architecture and the database (Backend), to an attractive and functional visual interface (Frontend), whether for a web page or a mobile application.

What can I offer you?

Full Product Development: I can build your entire web or mobile application from scratch. I ensure that all the internal machinery (backend) communicates perfectly with what the user sees (frontend).
Backend Specialist: Creation of robust and scalable solutions with Laravel (PHP), Java, and Python. API management, databases (MySQL), and server maintenance (Nginx).
Web & Mobile Development: Design of modern interfaces with Bootstrap/JS and creation of cross-platform mobile apps with Flutter and Dart.
Problem Solving: Technical support, bug fixing, and optimization of existing code.

Let's talk about your idea and make it a reality!
