I help businesses build AI powered applications using Python, machine learning, NLP, and LLMs. My work spans the full development lifecycle: data preprocessing, feature engineering, and model development through to deploying production ready applications with FastAPI, Flask, Docker, and Streamlit. I integrate LLM APIs (including Groq/LLaMA) and RAG architectures into scalable backend systems and client facing applications, alongside training custom models when a project calls for it. This includes everything from text classification and sentiment analysis to predictive modeling and time series forecasting. I also build audio transcription and speaker diarization pipelines for meeting and content processing use cases. Recent work includes a 5 model stacking ensemble (DistilBERT, RoBERTa, XGBoost) for text classification reaching 90%+ AUC, a Monte Carlo financial risk engine (FastAPI plus React) running 1,000 simulation VaR and Expected Shortfall calculations, and time series forecasting models that reduced forecast error by 18% against baseline. I also use explainability tools like SHAP and LIME so stakeholders can understand and trust model predictions, not just see a final output. In addition to personal and portfolio projects, I have successfully delivered AI and machine learning solutions for clients, maintaining a 5 star rating across 20+ Fiverr projects across industries including healthcare, finance, and restaurant analytics. I write clean, documented, containerized code and communicate clearly throughout a project, with regular updates so you always know where things stand. If you need an AI application built, an LLM integrated into your product, or a complete ML pipeline shipped end to end, let's talk about your project.
