PDF-Dark-Mode App:
Pet Navigator
This is a project that I had worked on during my free time while attending Central Washington University. It is a project I did using Visual Studio as the integrated development environment, the Visual Studio CLR C++ and .NET development kit, and Microsoft's SQLExpress as the server. The key things that I took from this project was learning more about C++ as a programming language, learning about how SQL works on a lower level, and learning about setting up and testing an SQL server.
Concept: Database Navigator that Shows Data of Pets
Dates Worked On: 10/19/2024 to 10/20/2024
Access to the Repository: https://github.com/10PAM/Pet-Database
Clockwork Universe
This is a project that I had worked on during my Senior year of High School, and is one of the most up to date showcase I have of video game development. In this, I used the Roblox Studio game engine, and I focused on memory optimization by ensuring lower 3D model polys to enhance performance, making use of client replication to optimize memory usage on the back-end, limiting nested logic statements when not needed to be nested, adding comments to my scripts to ensure ease of finding certain functions in case of needing to go and add, renove, or fix something, adding debounces to prevent excessive inputs, setting up cooldowns to towers as far as allowing a target to be damaged only once every other few seconds which can be seen with the "Flame Thrower" Trap while still allowing other targets to be damaged, using loops only when needed and on the client rather than on the server, and ensuring that player inputs were as bug free as possible. The key takeaway from this project that I had was memory optimization, ensuring fault tolerant logic, reusing functions to keep code small and concise, and most importantley improving my time management skills.
Concept: Tower Defense against Waves of Skeletons
Dates Worked On: 3/15/24 to 3/30/24
Access to the Game: https://www.roblox.com/games/15788568810/Clockwork-Universe
School Laptop Disassembly and Reassembly
This was a project we had done in my Cybersecurity vocational school (YVTECH), and the main focus of the project was to test our laptop dissambly and reassembly skills. I had not known much information about disassembling laptops before, but since we were able to chose one partner to be a team with, it helped us finish the project on time and with success. With this, I learned about ribbon wires. The key takeways that I had from this project were teamwork collaboration skills, reflecting on the importance of organizing to keep track of what was disconnected and what screws belonged to what, and improving my time management skills.
Dates Worked On: 6/7/2023
School PC Disassembly and Reassembly
This was another project we had done in my Cybersecurity vocational school (YVTECH), and the main focus of the project was to test our PC dissambly and reassembly skills. With this project, I had previous knowledge of building a PC when I built my own before, and thankfully I ended up the project on time and with a successful boot up. The key takeways that I had from this project were experience matters, being thoughtful of what is being removed and added, and improving my time management skills.
Dates Worked On: 6/6/2023
Personal PC Build
This is my current custom PC, which I built while saving up for a better computer than my previous one. At the time, I had an Amazon pre-built compact pc which I loved up until I started getting into making games and realized that I needed quite a bit more processing power. After a while of saving up, I managed to build this PC which with the use of YouTube, I managed to wire and learn about assembling and disassembling computers. One noteable thing that I loved from this project was being able to keep and install the 512 GB HDD which I got from my first PC and use as extra storage after partitioning it.

Understanding Graphics Programming
Author: Mario Aguilera Piceno | Date: 02/20/2026 | Last Edited: 02/20/2026 | Last Editor: Mario Aguilera Piceno
Developing a piece of software, even when following a teaching material can be quite time consuming but also rewarding when you get expected results. I am currently following along a book I purchased not long ago, Computer Graphics Programming in OpenGL with C++, 3rd Edition by V. Scott Gordon and John Clevenger, and this is exactly the experience that I have found myself in while following along with the book page by page. In this, I have been learning to how to set up and link libraries through Visual Studio.
If I had to set an end goal for this book, it would be to learn how to further expand my knowledge and build upon my Riova Game Engine project as I improve my object oriented programming knowledge in C++. Graphics programming is one of the most intriguing things to me when it comes to understanding video game development. Given the fact that it is used extensively throughout the video game industry to render games and even movies, it is something that has become a passion for me to understand.
