About this gig

Are you looking for a machine learning engineer who actually builds models not just calls APIs?

I specialize in multimodal AI, NLP, and computer vision. I've built production pipelines using Whisper ASR, Vision-Language Models (Qwen2.5-VL), and custom hallucination detection systems that reduced transcription errors by 64%.

What I can build for you:

Custom classification, regression, and NLP models (text, audio, image) Fine-tuning LLMs and Vision-Language Models on your data Speech-to-text and transcription pipelines (multilingual support) Data preprocessing, feature engineering, and evaluation pipelines Computer vision systems (object detection, OCR, image classification) Prediction models and data analysis pipelines

My stack: Python, PyTorch, Scikit-Learn, HuggingFace Transformers, Pandas, NumPy, OpenAI Whisper, Qwen2.5-VL

How it works:

  1. Share your problem and data I'll assess feasibility
  2. I build, train, and evaluate the model with documented metrics
  3. You receive clean code, trained model, evaluation report, and deployment instructions

Every delivery includes: source code, requirements.txt, a README with setup instructions, and a results summary.

I build AI systems that work in production, not demos. Developed multimodal AI pipelines using Whisper, Qwen2.5-VL, and custom hallucination detection - 64% error reduction. I fine-tune models with PyTorch, HuggingFace Transformers, and Scikit-Learn. Also build full-stack web apps: ASP.NET Core 8.0, SQL Server, Stripe, Docker deployment. What I deliver: - ML models and fine-tuning (NLP, CV, multimodal) - AI chatbots and RAG systems - Full-stack web apps with AI integration - Data pipelines and automation 5-star rated. Clean code, on time, every time.
