Experience

Where the work has been.

The tracks I have actually shipped in, in the order I grew into them — classical machine learning first, then deep learning and vision, then generative AI, and now whole-system architecture around all three.

Practice areas

Four tracks that overlap rather than replace each other. I still take classical machine learning work when it is the honest answer to the problem.

  1. 2022 – Present

    Machine Learning Model Development

    Designed and deployed ML models for real-world prediction tasks like heart disease detection, customer churn, and salary prediction. Expertise in scikit-learn, hyperparameter tuning (GridSearchCV, K-Fold), and statistical data analysis.

  2. 2022 – Present

    Deep Learning & Computer Vision Projects

    Built and trained CNN & ANN models using TensorFlow and PyTorch. Delivered OCR systems, disease detection models, and real-time object tracking with YOLO, image segmentation, transfer learning, and SMOTE augmentation.

  3. 2023 – Present

    Generative AI & LLM Engineering

    Built advanced AI apps using OpenAI, Hugging Face, DeepSeek, and Langchain. Specialized in RAG systems, vector search (FAISS, ChromaDB), agent frameworks (CrewAI, LangGraph), and fine-tuning LLMs with LoRA/QLoRA.

  4. 2023 – Present

    AI System Architecture & Solution Design

    Designed scalable end-to-end AI systems with multi-agent collaboration, API orchestration, and ethical AI practices. Mapped business use-cases into modular AI solutions using modern stack.
