About

Professional summary

I am an AI Engineer and Senior Data Scientist with five years of professional experience spanning artificial intelligence, data science, and software engineering. I specialize in building production-grade AI systems, with particular focus on large language models, retrieval-augmented generation, natural language processing, and real-time speech AI.

I build and deploy LLM agents, RAG applications, speech diarization systems, database agents, and multimodal AI solutions. My work combines strong machine learning foundations with backend engineering skills using Python, FastAPI, Flask, Django, REST APIs, WebSockets, and graph databases.

I have hands-on experience with PyTorch, TensorFlow, Hugging Face, LangChain, vLLM, ChromaDB, Neo4j, Docker, AWS, and MLOps practices. I am comfortable taking AI products from experimentation and model evaluation through deployment, optimization, monitoring, and integration with business systems.

I have worked as an AI Engineer, Data Scientist, AI Instructor, and Flutter Software Engineer. I enjoy mentoring learners in AI, machine learning, deep learning, cloud services, and end-to-end model deployment while delivering measurable business improvements through applied AI.

I am also a published researcher, Kaggle Bronze Medalist, open-source developer, and technical writer. My research and projects cover Arabic AI, computer vision, LLM evaluation, transformer architectures, speech-to-sign-language systems, and efficient inference for local language models.

Career history

AI Engineer for R&D AHBS

Developed unsupervised multi-view cluster ensemble and quality-gate classification systems using stylometrics, POS tagging, embedding models, soft voting, and bootstrapping. The resulting classifier achieved 91% accuracy.

Built production AI solutions including a FastAPI and Neo4j code graph, LLM database agent, speech diarization pipeline, pharmacist assistant, Microsoft Teams and SharePoint document-analysis agent, and ADR review chatbot. These systems improved code comprehension, meeting handovers, and engineering decision-making efficiency.

AI Instructor National Telecommunication Institute

Teach AI-focused courses for postgraduate students, with a reported 90% success rate. Deliver instruction on computer vision, reinforcement learning, Stable Diffusion, transformer architectures, GPT, BERT, T5, and retrieval-augmented generation.

Prepare learners for industry roles through practical AI curricula and applied projects.

AI Instructor Digital Egypt Pioneers Initiative

Delivered instructor-led training in artificial intelligence, machine learning, and data engineering for undergraduate students.

Provided hands-on AWS and MLOps experience, mentoring teams as they built and deployed their first end-to-end deep learning models.

Data Scientist Orange Innovation

Earned a Kaggle Bronze Medal in the LLM Science Exam competition using LLM fine-tuning methods including LoRA, QLoRA, and Mixture of Experts.

Maintained and optimized a deployed AI summarization service, improving efficiency and accuracy by 10% and reducing inference time and operational costs by 5%. Built a real-time screen-content AI assistant and researched LLM carbon footprint and emissions.

AI Trainee National Telecommunication Institute

Selected from more than 1,000 candidates across Egypt and graduated first in the AI track with a 98% score.

Gained practical experience training, evaluating, and optimizing machine learning and deep learning models on real-world datasets.

Software Engineer (Flutter) XIMA Systems

Served as the sole Flutter developer for the company's cross-platform mobile application.

Delivered and released the application to both Google Play and the Apple App Store.

Software Engineer (Flutter) Voucherek

Worked remotely as the sole Flutter developer for a Saudi e-commerce company.

Inherited a buggy acquired codebase and progressively rebuilt it module by module using the Strangler Fig pattern, stabilizing the full application and its business logic.
