About

I combine backend, product thinking, and execution to turn ideas into useful software.

I have built web platforms, administrative systems, microcomputer solutions, and internal tools for real business operations.

I am especially comfortable designing databases, APIs, authentication flows, admin panels, and processes where reliability is critical.

Although backend is my strongest area, I can also work with modern frontend stacks to deliver complete end-to-end products.

Project Development Manager

DIGITAL SYSTEMS EVOLUTION

January 2026 — Present

Valencia, Venezuela

Led the development and technical strategy of a smart management suite (onpass, onparking, onrecon), connecting cloud software with physical hardware to automate access and facility control. • Architecture & IoT: Designed scalable hybrid infrastructures, integrating web applications (AWS) with local microcomputers and physical peripherals (sensors, barriers). • AI & Computer Vision: Implemented facial recognition and image processing systems using OpenCV and AI for automated identity verification. • Technical Leadership: Managed the entire product lifecycle applying KISS principles to avoid over-engineering, achieving robust APIs and real-time data synchronization. • Full-Stack Development: Built robust management platforms using PHP/Laravel, React, Inertia, TypeScript, and Python, optimizing both web control panels and the operational software of local modules.

EZPASS

System for the administration of clubs or urbanizations at accounting level, access control and other aspects (Currently under development). Personal achievements in the project: Web App developed using Laravel - Blade - PHP, following the MVC architecture, MYSQL database, AWS WEB services, app deployed also in AWS as well as the database and buckets, notification system using Laravel technology as well as sending notifications via SMS using own devices, development of APIs for the communication of devices or modules used in access control. Development of python programs to control the modules, creation of local database synchronization system between the modules, use of database libraries to control them, OpenCV for image processing, TtkBootstrap to create a simple interface for the modules, control of physical pins of the modules (microcomputers) to manage external hardware (sensors, lights, cameras)...
