About

Professional summary

I am an AI and Machine Learning Engineer specializing in agentic systems, retrieval-augmented generation (RAG), natural language processing, and computer vision. I build intelligent applications that combine robust model evaluation, backend engineering, and practical product integration.

I have architected LangGraph-based orchestration and RAG pipelines for a medical assistant, including safety-focused routing, semantic retrieval, real-time web search, and LLM-driven decision paths. My work emphasizes reliable tool use, traceable workflows, and contextually relevant outputs.

I have hands-on experience developing and evaluating Transformer-based NLP systems for question answering, summarization, semantic search, and named entity recognition. I also work with Python machine learning ecosystems including PyTorch, TensorFlow, and scikit-learn.

In computer vision, I led the evaluation and integration of multilingual lip-reading models. I verified 99.1% word-level accuracy for an English model aligned with Meta's published benchmark and contributed to research evaluation for Arabic and sentence-level lip-reading systems.

I also have backend AI engineering experience with FastAPI, Node.js/Express, Docker, PostgreSQL, authentication, API usage metering, billing workflows, Stripe webhooks, and background processing. I am fluent in English and a native Arabic speaker.

Career history

AI Training & Evaluation Specialist - Freelance Alignerr

I conduct agent error analysis and function-calling validation for multi-step reasoning and API logic. I audit agent behavior to identify reliability issues and improve execution quality.

I evaluate model alignment by comparing recursive agent outputs against corrected versions. This work supports more consistent decision-making and improved model reliability.

AI Backend Engineering Intern FlyRank AI

I completed parallel AI Fluency and Backend AI Engineering internship tracks, delivering more than 12 projects using FastAPI, Node.js/Express, and Docker. I built supporting AI and backend solutions including RuleGuard AI, Decision Flow Studio, JWT authentication, report processing, PDF generation, and web scraping.

For my capstone, I architected a multi-tenant usage metering and billing engine with idempotent request handling, tenant-level monthly quotas, and integer micro-unit cost calculations. I synchronized subscription state through verified Stripe test-mode webhooks and implemented a background reconciliation process with retries and terminal-failure handling.

NLP Engineering Intern Elevvo

I developed Transformer-based BERT and T5 solutions for question answering and text summarization. I optimized model performance using ROUGE and F1 evaluation metrics.

I also built semantic search and named entity recognition pipelines using Sentence Transformers and spaCy. These pipelines supported automated ranking and entity extraction workflows.

Machine Learning Engineering Intern Digital Egypt Pioneers Initiative (DEPI)

I applied transfer learning techniques to build neural networks for NLP and computer vision tasks. I worked across machine learning workflows involving model development and experimentation.

I streamlined data analysis and model evaluation pipelines to support more efficient experimentation and performance assessment.

Machine Learning Intern NeuronetiX

I developed five machine learning solutions spanning supervised learning, unsupervised learning, and reinforcement learning. I implemented end-to-end workflows using Python, scikit-learn, and TensorFlow.

My work covered practical model development, experimentation, and evaluation across multiple machine learning problem domains.
