Analista de Sistemas – Portafolio Académico de Marlon Fernando Aguilera.

A modern digital dashboard mockup displayed on a large, ultra-wide monitor in a dimly lit office, showing a comprehensive inventory management system for a small business: real-time stock levels, reorder alerts, supplier performance charts, and process flow indicators. The interface uses a professional palette of deep blues, whites, and accent oranges, with clear typography and well-organized panels. The monitor sits on a minimalist black desk with only a keyboard and a closed systems analysis textbook. Cool, focused screen light is the primary source, casting subtle reflections on the desk surface and creating a concentrated, analytical mood. Photographic realism, straight-on composition, with a slight vignette emphasizing the glowing screen.

Proyectos y casos de estudio

En esta sección presento proyectos centrados en el diseño e implementación de un sistema de inventarios para Pymes, aplicando el ciclo de vida del desarrollo de sistemas (SDLC). Cada caso resume el contexto, los problemas detectados y las soluciones propuestas desde el rol de analista de sistemas.

Proyecto principal

Sistema de inventarios para PyME

Este caso describe el contexto de una PyME con problemas de control de inventarios, la identificación de requerimientos y el diseño de un sistema orientado a reducir quiebres de stock, mejorar la rotación de productos y apoyar la toma de decisiones con información confiable.

Ver detalle
A tidy desk setup featuring an open notebook with handwritten system requirements for a PyME inventory system, alongside printed use case scenarios and a detailed context diagram. A slim tablet displays a wireframe of an inventory control dashboard with neatly organized widgets and metrics. The desk is a light oak surface, with a single small plant and a closed stack of reference binders labeled “Análisis”, “Diseño”, and “Implementación”. Soft, diffused afternoon light from the side casts gentle shadows, creating a calm, studious mood. Photographic realism, medium close-up shot from a slightly elevated angle, with shallow depth of field that keeps the documents and tablet in sharp focus while the background fades softly.
A large whiteboard wall filled with meticulously drawn UML diagrams, inventory workflows for a small business, and color-coded sticky notes representing SDLC phases. Bold arrows connect analysis, design, development, and implementation, with a clearly circled “Agente de Cambio” phrase in the center. Below, a minimalist floating shelf holds technical books, including a prominently placed Kendall & Kendall systems analysis text. Natural overhead office lighting creates an even, neutral illumination with soft reflections on the whiteboard surface. Photographic realism, shot from a slightly wide, eye-level angle to capture the full expanse, clean and modern aesthetic, evoking a strategic, analytical, and academic atmosphere.
A sleek glass-and-metal workstation table covered with neatly arranged system analysis artifacts: printed data flow diagrams, entity-relationship models, and a clearly labeled SDLC lifecycle poster. Beside them, an open high-resolution laptop screen displays a dashboard for a small business inventory system with clean charts and tables. The surface is a dark matte wood, with a subtle reflection of the screen glow. Soft daylight from a nearby window illuminates the scene, creating gentle shadows and a professional, focused mood. Photographic realism, eye-level composition with a slight angle, sharp focus on the documents and screen while the background office shelves and whiteboard fade into a soft bokeh blur, conveying structured thinking and organized analysis.
