Talha O.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

Hi, I’m Talha, an AI Engineer and Machine Learning developer specializing in Speech AI, ASR, Text-to-Speech (TTS), NLP, model fine-tuning, Python development, API development, and GPU inference optimization. I build and deploy production-ready AI systems using Python, PyTorch, TensorFlow, Hugging Face, Transformers, ONNX, CUDA, REST APIs, and modern machine learning frameworks. My main areas of expertise include: • AI & Machine Learning Development • Deep Learning and Neural Networks • Speech Recognition / ASR • Text-to-Speech / TTS • Voice Cloning and Speech-to-Speech AI • Natural Language Processing / NLP • Machine Translation and Multilingual AI • Hugging Face Transformers and PyTorch • Model Fine-Tuning and Custom Model Training • CTC, Transformer and Encoder-Decoder Models • GPU / CUDA Inference Optimization • MPS Kernels Optimization • ONNX Model Optimization and Deployment • AI API Development with FastAPI in python • REST API Integration and Backend Development • Web Scraping and Browser Automation • Python Automation and Scripting • Data Collection, Cleaning and Preprocessing • Dataset Creation and Annotation Pipelines • AI Model Debugging and Performance Optimization I can work with an existing machine learning or AI project to debug, optimize, fine-tune, or deploy it, or develop a complete solution from scratch, including data preparation, model training, evaluation, inference optimization, API development, and production deployment. I also have experience optimizing AI inference for real-time and high-throughput workloads, including GPU-resident models, batching, memory optimization, ONNX inference, CTranslate2, llama.cpp, and low-latency APIs. My focus is not just training models in notebooks. I build AI systems that can actually be integrated and deployed in production. If you need an AI Engineer, Machine Learning Engineer, Python Developer, Speech AI Developer, NLP Engineer, or AI API Developer, send me your project requirements and I’ll help you find the right technical approach.
