Ritik D.

Hey! I'm Ritik — an AI/ML engineer based in Paris with a Master's in AI from EPITA and 4+ years of hands-on experience in data and machine learning. I started in data analytics, and now I build end-to-end ML systems — from raw data all the way to deployed, monitored production models. Here's what I can help you with: → LLM applications: build RAG pipelines, chatbots, and semantic search from scratch to deployment → Deep learning: design and train custom models for computer vision, NLP, audio processing, and sequence modeling using PyTorch and TensorFlow → Data science: solve business problems using the full toolkit: classification, regression, time series forecasting, NLP, sentiment analysis, and ensemble methods including bagging, boosting, and stacking → Production ML: architect complete pipelines with automated training, model versioning, drift detection, real-time monitoring, and CI/CD → Recommendation engines: build personalized systems using collaborative filtering, deep retrieval models, and approximate nearest neighbor search at scale → Cloud & big data: design end-to-end cloud architectures on AWS including serverless pipelines, containerized services, data lakes, and real-time processing with Spark and Hadoop Some things I've built: an award-winning emotion-driven music generator using latent diffusion, a YouTube recommendation engine with deep retrieval + FAISS, RAG-powered research paper QA, a full healthcare cloud platform on AWS with serverless compute and ML integration, and production ML pipelines with automated retraining and monitoring dashboards. Happy to chat about your project.
