Hi there! I'm Vongai. 👋 Welcome to my GitHub Portfolio 💻


I'm a recent summa cum laude IT graduate from Kennesaw State University. I recently built a machine learning classifier model from scratch using the python libraries NLTK and Scikit-Learn for NLP and model training to predict user sentiment from text without relying on HuggingFace transformers. I used 42,000+ user feedback dataset entries and achieved a 56% accuracy rate for emotion detection in the first 2 weeks of the project. This was part of an end-to-end Customer Support AI application I built with Python, React/TypeScript, Azure, and ML/LLM models that processed 1,000+ customer feedback entries and automated 80% of the manual response work. I'm a problem-solver with proven ability to analyze systems, secure infrastructure, design data pipelines, and support users.

I have hands-on experience in full-stack development, machine learning, cloud systems, database work, cybersecurity, and technical support.

Find my work below.


🚀 Featured Project: CapSense AI — Sentiment Analysis & Response Generation

Overview
CapSense AI is a full-stack system for enterprise customer feedback: sentiment, emotion, sarcasm, aspect analysis, plus empathetic responses via Phi-3 Mini. Built with React, Flask, and Azure. Supports single input and CSV batch processing.

Key features

  • Sentiment classification (positive / neutral / negative)
  • Emotion detection (anger, joy, anticipation, neutral, disgust, sadness)
  • Sarcasm detection
  • Aspect-based sentiment analysis
  • Empathetic AI responses (Phi-3 Mini)
  • CSV batch processing + Sentiment Analysis Report UI
  • Azure App Services + SQL DB integration

Tech stack

  • Frontend: React 18, Vite, Bootstrap, Chart.js
  • Backend: Python 3.9+, Flask, PyODBC, joblib, NLTK
  • ML: Naive Bayes (emotion), Hugging Face transformers (sarcasm)
  • Cloud & CI: Azure AI Studio (Phi-3), Azure App Services, GitHub Actions

Highlights

  • Naive Bayes emotion classifier trained on 42k+ samples
  • Modular React UI with report components for each detector
  • Robust backend endpoints for individual & batch analysis
  • Edge-case handling for empty/malformed/large CSVs
  • Production deployment and Azure optimizations
