🚀 Computer Vision | NLP | AI Engineer | Machine Learning & Deep Learning | AI SaaS & Automation Bringing AI-Powered Innovation to Enterprises I am an AI engineer with over 11 years of experience in developing deep learning solutions, natural language processing, and computer vision. My journey in AI started more than a decade ago, working on advanced projects that helped businesses automate processes, analyze data, and make smarter decisions. Four years ago, I joined Upwork to offer my expertise globally, successfully delivering impactful projects in areas such as: ✅ Text classification and sentiment analysis using advanced NLP models ✅ AI-driven cybersecurity solutions for IoT network traffic analysis ✅ Medical image analysis using CNN-based models for enhanced diagnostics I took the challenge. I optimized the dataset, fine-tuned an Arabic NLP model, and streamlined the preprocessing pipeline. Within days, the classification accuracy improved significantly, and the client was thrilled. Soon, larger companies started noticing my work. Then came a cybersecurity firm struggling with IoT traffic vulnerabilities. Their system was unable to detect threats effectively. I built a CNN-based model that analyzed real-time network traffic, improving threat detection accuracy by 40% while reducing false positives. Another client, a healthcare startup, faced challenges in medical image analysis. I developed a deep learning model using CNNs for ultrasound image quality assessment, ensuring reliable diagnostics. This solution reduced errors and improved medical imaging workflows. One of my most demanding projects involved incremental learning for AI models. The challenge was to update a deep learning model with new data without forgetting previous knowledge. By implementing advanced transfer learning techniques, I ensured the model retained past insights while adapting to new patterns. That $50 project was more than just a small job—it set me on a path to solving complex AI problems and driving impactful innovation. And this? It’s just the beginning. Now, We Build AI Solutions for Enterprises Worldwide Today, I lead a team of AI specialists, delivering state-of-the-art solutions in machine learning, deep learning, NLP, and computer vision.

I am a Machine Learning Engineer with four years of experience working across deep learning research, large scale AI systems, and production model deployment. Over the years, I have worked extensively in medical imaging, computer vision, NLP, signal processing, and large language models, building systems that range from experimental research pipelines to deployed real world AI applications. My day to day work primarily involves Python, PyTorch, TensorFlow, Keras, HuggingFace Transformers, sentence transformers, scikit learn, OpenCV, Pandas, and NumPy. I enjoy working deeply on both the research and engineering sides of machine learning, especially problems that require understanding model behavior rather than simply applying existing architectures blindly. A large part of my background is research driven. I have authored multiple peer reviewed publications in indexed journals and IEEE conferences, including publications in Neurocomputing, Healthcare Analytics, Engineering Applications of Artificial Intelligence, Telematics and Informatics Reports, and other Elsevier and IEEE venues. My research has focused heavily on explainable AI, healthcare AI, and advanced deep learning systems. Some of my published work includes CARDxnosis, an explainable knowledge driven framework for ECG diagnosis and clinical report generation, an explainable AI system for trustworthy arrhythmia detection, a CNN RNN Attention hybrid architecture for automatic modulation classification, ensemble deep learning approaches for lung cancer detection from CT scans, and SRGAN based white blood cell image generation and classification pipelines. Alongside published work, I am currently involved in research on brain tumor segmentation, ADHD and ASD classification from brain connectome graphs, epileptic seizure prediction from EEG signals, and interpretable tabular learning using graph neural networks combined with Kolmogorov Arnold Networks. Beyond research, I have substantial hands on experience building and deploying production grade AI systems. One of my major recent projects was LaborBERT v4, a domain adaptive transformer fine tuning system processing hundreds of thousands of records through a large scale training pipeline. The project involved multiple experimental setups including contrastive learning, masked language model pretraining, temporal contrastive learning, cross attention based fusion, multi task training, and Matryoshka Representation Learning. I have also built hybrid embeddings plus LLM systems for taxonomy mapping using OpenAI embeddings alongside locally hosted LLaMA and Mistral models through Ollama. In addition, I have worked on deployed clinical AI systems and a portable on device diagnostic AI solution with embedded deep learning models for point of care inference, which gave me valuable experience in optimization, deployment constraints, inference design, and production reliability. My broader project portfolio includes vehicle detection using Mask R CNN, human activity recognition on the Kinetics 700 dataset, facial keypoint detection with MultiRes UNet, semantic segmentation pipeline redesign, Stable Diffusion based image editing workflows, toxic comment classification, RASA based conversational AI systems, and large scale scraping and automation pipelines using Playwright and Selenium. I have also worked with Flask and Django based deployment pipelines and cloud hosted ML systems. From an engineering perspective, I care strongly about clean and maintainable systems. I follow disciplined workflows involving modular code design, Git based version control, reproducible experimentation, structured evaluation, bootstrap validated metrics, and detailed documentation. I am also comfortable preparing scientific reports, research papers, and journal submissions using both LaTeX and Word. What ties all of this together is that I genuinely enjoy solving difficult technical problems, especially the kind that require balancing research depth with practical engineering constraints. I am most motivated by projects where thoughtful experimentation, careful system design, and real world usability matter equally.
