This is a work-in-progress application that was also part of a university final for the Database 3 course. It demonstrates knowledge about non-relational databases, specifically graph NoSQL databases (Neo4j).
I proposed a solution for a social network where users can create profiles, follow each other, and view the relationships between users.
Additionally, users can create posts, comment on them, and see posts from followed users. They can like or comment on posts as well. The app includes suggestions for connections if you don't follow someone and a user search system. I plan to continue expanding this app in the future.

At this moment, I have only modified the legacy code. Initially, I developed it in Flask due to the speed of implementation—I programmed it in just one day, and it was part of the practical demonstration of the project. Although this demonstration was not required, I liked the idea of showcasing it visually and practically as a REST API.
For better integration with my portfolio, I migrated it to Django. Additionally, I implemented data sanitization to prevent XSS (Cross-Site Scripting) attacks and added validation to ensure that the session token is unique. Even though the probability of a 128-bit token collision is negligible, I included a verification step to check if it already exists in any active session before using it, preventing session overlaps. Other than these changes, the rest of the code remains legacy, and I will leave it as is for now. Soon, I plan to redesign it with Bootstrap for a more elegant look.

This is a project I created for the final of a university course, where we had to demonstrate the knowledge acquired in the class. It is based on a medical scheduling application where you can book appointments, view your booked appointments, modify them, and cancel them. It features multiple users, such as patients, doctors, and administrators, each with different hierarchies and permissions. The application connects to an SQL database to process queries, return results, or store data to maintain its integrity over time.

I manage the systems for Reforestación Alimentaria, an NGO dedicated to environmental regeneration through reforestation with edible and fruit-bearing plants. My role includes maintaining and optimizing their web infrastructure to ensure a smooth user experience and reliable access to their resources. This involves: Website Maintenance & Optimization: Keeping the site functional, secure, and up to date. Security Enhancements: Implementing data sanitization and protection against vulnerabilities like XSS. Performance Improvements: Ensuring fast load times and stable server-side operations. System Scalability: Preparing the platform for future growth and potential feature expansions. While my contribution is primarily technical, I align my work with the NGO's mission, ensuring that their digital presence supports their efforts effectively. Future improvements include refining the design using Bootstrap and further enhancing system security.

Although I don’t have many public projects to showcase, I have extensive experience and practice in various fields, including scripting, web scraping, chatbots, Binance bots, WhatsApp bots, socket connections, cookie extractors, bit injection, and reverse engineering with Ghidra and C++. I have worked on many personal projects, server deployments, and Linux server configurations, along with numerous private projects that demonstrate my versatility and skills.
