About

I build Data & AI systems that work in production not just in notebooks. Recently graduated with an MS in Data Science from the University of North Texas, where I focused on applied machine learning, generative AI, NLP, data engineering, and production-oriented AI systems. My work sits at the intersection of data, software, and AI: building ML pipelines, designing RAG-based applications, integrating LLMs with real workflows, and turning messy data into useful decisions. What I have shipped some of them are : • ClaimShieldAI : AI-powered insurance claims assistant using RAG, LLM orchestration, and workflow automation. • MedTranslateAI : medical translation assistant focused on multilingual NLP and practical healthcare communication. • Jarvis-Techie AI Assistant : voice-enabled AI assistant with tool-use, memory, and agentic workflow capabilities. • Airfare Price Prediction : machine learning system using feature engineering, model evaluation, and price prediction research. • Customer Churn Prediction Analysis : classification pipeline using ML models, feature analysis, and business-focused churn insights. • Driver Drowsiness Detection System : real-time computer vision system for fatigue detection using eye and facial movement signals. See the Projects section for additional AI, ML, data, and software work, with source code available on GitHub. As a Graduate Student Assistant at UNT, I support applied data and AI work through data preprocessing, exploratory analysis, ML experimentation, research support, dashboarding, and technical documentation. I am also an open-source contributor and GitHub builder, with projects across GenAI, machine learning, computer vision, data analytics, web systems, and applied AI. Core stack: Python · SQL · Machine Learning · NLP · GenAI · LLMs · RAG · LangChain · LangGraph · MCP · Vector Search · Azure AI · Scikit-learn · TensorFlow · PyTorch · XGBoost · Spark · Tableau · Git · GitHub · CI/CD I am especially interested in roles where I can build reliable AI systems, improve decision workflows, work with real users, and translate business problems into technical solutions. Target roles: Forward Deployed Engineer · AI Engineer · Generative AI Engineer · Machine Learning Engineer · Data Scientist 📍 Denton, TX | Open to W2 opportunities across Data Science, AI Engineering, Machine Learning Engineering, Generative AI, and related Data & AI roles. 🔗 GitHub: github.com/Techie03 If your team is building production Data & AI systems, I would be happy to connect.
