Ai model for diagnostics in Mental Health Field

My most recent project is not public as of yet, it is functional and all existing portions are built, however it is not fully implemented. However it demonstrates all the four pillars in it's current form quite effectively. I was made aware of that acronym recently and I figured it was worth noting I know all those pillars well enough to write a program with them. https://github.com/RexfordProgrammer/MedInformer
Predictive model using Machine Learning

I developed a Python script that leverages machine learning to predict stock movements, utilizing powerful libraries such as Scikit-learn (sklearn), NumPy, and Pandas to process financial data and generate predictive models. The script begins by gathering and cleaning historical stock data, using Pandas for data manipulation and feature engineering to extract meaningful indicators like moving averages, volatility, and trading volumes. With NumPy, it efficiently handles numerical computations to prepare the dataset for analysis. I implemented machine learning algorithms from Scikit-learn, such as logistic regression, decision trees, or support vector machines, to train models on the processed data and identify patterns indicative of price movements. The script evaluates model performance using cross-validation techniques and fine-tunes hyperparameters to improve prediction accuracy.

Web Skimmer for Internships

In 2023, I developed a Python-based Web Skimmer that automates the search and notification process for available internship opportunities, showcasing my skills in web automation, data extraction, and email communication. Utilizing Pyppeteer, a powerful headless browser automation library, the script efficiently navigates multiple job listing websites, dynamically interacts with web elements, and scrapes relevant internship postings based on specific criteria such as location, industry, and application deadlines.

ESP32 Humidistat Project

In 2022, I engineered an ESP32 Humidistat using C++ to accurately monitor and display ambient humidity levels, showcasing my proficiency in embedded systems and hardware integration. The project utilized a Generic LCD for clear, real-time data visualization and a DHT22 sensor for precise humidity and temperature measurements. I implemented and customized libraries specific to both the LCD and DHT22 sensor, ensuring seamless communication and reliable data retrieval.

Batch File Alarm Clock

I developed a Batch File Alarm Clock to showcase my expertise in batch scripting and system automation by leveraging multiple batch file variations to dynamically create, modify, and manage Task Scheduler events, effectively transforming Task Scheduler into a customizable alarm system. This project integrates NIRCMD to adjust system volume and control other peripherals, ensuring the alarm operates according to user preferences. The alarm is executed through Task Scheduler tasks that run batch scripts to play sounds, display notifications, and manage device settings seamlessly.
https://github.com/RexfordProgrammer/Batch-File-Alarm-ClockTo showcase my skills with Batch files, I created a "Batch File Alarm Clock." This project uses multiple batch file variations to modify Task Scheduler events, effectively functioning as an alarm clock. I also integrated NIRCMD to adjust volume and control other devices while using a task in Task Scheduler to run a the actual alarm.

Customized Marlin Build, for SKR Mini E3 Mainboard

In early 2022, I configured and compiled a custom version of Marlin firmware for my custom 3D printer. You can check out the code on GitHub!

Flesh Gameplay

Sugarcane Madness
This zombie top-down shooter game was created in 2016 when I was 17 for my final project in AP Computer Science. I find it historically interesting for my programming journey, so I still keep it around.
This old project showcases inheritance, encapsulation, polymorphism, and more, although it doesn't fully adhere to SOLID programming principles.

Check out this mod video from when I was just 13! Below is the link to the mod. I'm not sure how many people saw it, but I find it fascinating that there are even videos dedicated to reviewing it—especially in Portuguese. Clearly, the folks in Portugal have a passion for sugarcane. A mod created by a 13-year-old American being reviewed by Portuguese enthusiasts? Who knew that was possible! The mod was written in Java.
Where my interest in programming began

Where my interest in programming began
The earliest code I've written (that I was able to locate) was found in some old files from my first windows laptop. I removed the hard drive and found a workspace directory, which was related to an eclipse instance, on the default user. There I found a number of "calculators" written in java (complete with incorrect naming conventions, capitalization, and spelling) which I used to do my homework more "efficiently". I had some excel files doing similar jobs but I enjoyed toying with java programs to do similar jobs.
Some example code is on another page, for your viewing.

All of the files are available on GitHub, most of them uncommented and unadulterated.
