- Led the system integration and personally developed the core Chatbot (GPT-40) and Emotion Recognition (YOLOv8, ConvNext) modules for a real-time, voice-interactive NPC.
- Engineered a multi-threaded Python application to process user speech, analyze biometric facial data for emotional state, and generate character-driven, emotionally nuanced responses.
- Successfully integrated four distinct machine learning systems (Speech-to-Text, Emotion Recognition, Chatbot, and Text-to-Speech) to create a seamless and immersive user experience.
Project Lead & System Architect
ArgusML - Online Machine Learning Platform
02.2024 - 07.2024
- Led a team of six developers, architecting a full-stack MERN application, and a Python-based machine learning pipeline to allow users to train their own ML models.
- Collaborated on the implementation of all major project components, working directly with teammates to develop the Express.js API, design the MongoDB database schema, build the React.js front end, and engineer the Python machine learning scripts.
- Spearheaded the complex integration of the Python ML scripts with the Node.js back end, guiding the team to use child processes for execution, and Socket.IO for real-time training updates to the client.
- Managed the complete project workflow, and facilitated all cross-component communication, personally resolving development roadblocks, and ensuring a cohesive final product.
