Experience
PwC ETIC — AI Engineer
June 2026 — Present
- Worked in a team building an internal plugin that makes PDF and Microsoft Office documents compliant with PwC standards.
Advanced Computer Technology (ACT) — Software Developer (AI & Backend)
Oct 2025 — June 2026
- Built a multi-agent hotel concierge in LangGraph for guest requests and policy questions, with 95% intent classification accuracy.
- Built hierarchical RAG pipeline on PGVector for hotel policy documents; recursive retrieval cut hallucinations on long queries by 30%.
- Connected the agents to Oracle OPERA PMS via REST APIs to create and track guest service requests, cutting manual front-desk entry by an estimated 40%.
- Built voice agents on LiveKit and ElevenLabs: a multilingual hotel agent connected to OHIP / OPERA Cloud, and an Egyptian Arabic ordering agent connected to Oracle Simphony POS.
- Containerized the entire multi-agent stack using Docker, streamlining the CI/CD pipeline and reducing deployment downtime across internal testing environments.

Oct 2024 — Apr 2025
- Completed the Microsoft Machine Learning Engineer track, focusing on designing scalable and production-ready machine learning solutions using Microsoft technologies.
- Built strong foundations in statistics, linear algebra, Python, data preprocessing, visualization, classical ML, deep learning, NLP with attention mechanisms, and computer vision using transfer learning.
- Applied Azure AI Fundamentals and Azure AI Engineer Associate concepts, with hands-on exposure to MLOps tools including MLflow and Hugging Face.
Orange Egypt — Data Engineer Intern
Aug 2024 — Sep 2024
- Automated and optimized ETL workflows for voucher data using Apache NiFi and dbt, improving data quality and reliability.
- Explored pipeline orchestration and scheduling with Apache Airflow to increase automation and reduce manual data-handling effort.
ValU — Data Science Intern
July 2024 — July 2024
- Analyzed company growth metrics and customer behavior to generate data-driven strategic insights.
- Designed and delivered interactive Power BI dashboards visualizing KPIs, improving executive decision-making.
- Built and evaluated ML models (Random Forest, XGBoost) for customer lifetime value prediction, achieving an AUC of 0.70.
- Contributed to a customer-facing chatbot by unifying vendors and geographic regions using Named Entity Recognition (NER) for accurate offer retrieval.
- Optimized LLM prompts for intent extraction and analyzed OpenAI API usage, reducing inference costs by approximately 30% while maintaining response quality.
Advanced Computer Technology (ACT) — Data Science Intern
Aug 2023 — Sep 2023
- Conducted EDA on large datasets and presented insights to stakeholders.
- Automated web scraping pipelines using BeautifulSoup.
Projects
AI-Powered Tech News Aggregator (n8n, LLMs)
- Built an automated news aggregation pipeline using n8n to ingest RSS feeds from multiple tech sources on a scheduled basis.
- Implemented an LLM-based classification and ranking system to categorize articles, generate why-it-matters insights, and score news importance.
- Designed daily and weekly workflows to store structured results in Google Sheets and deliver curated HTML email summaries of top-ranked articles.
AutoML Pipeline (scikit-learn)
- Engineered a modular AutoML pipeline in Python (scikit-learn) with 4 stages: preprocessing, feature selection, model selection, and hyperparameter optimization.
- Synthesized AutoML foundations (model selection, HPO, evaluation) into the system architecture and experiment plan.
- Implemented and benchmarked Grid Search, Random Search, and Bayesian Optimization for HPO on tabular ML tasks, analyzing trade-offs in performance and compute cost.
RAG Chatbot (LangChain + FAISS + Ollama)
- Built a retrieval-augmented chatbot with LangChain + Ollama Gemma-3 (12B) and a Gradio UI for real-time Q&A.
- Crawled up to 30 LangChain doc pages (BeautifulSoup); chunked via RecursiveCharacterTextSplitter.
- Embedded with all-MiniLM-L6-v2 and indexed in FAISS; boosted relevance using MultiQueryRetriever + ContextualCompressionRetriever; added SerpAPI + Python REPL tools.
ExpenSum — Smart Expense Tracker (React + Spring Boot + JWT + LLM)
- Developed a full-stack expense tracker: React frontend and Spring Boot backend secured with JWT authentication.
- Integrated Mistral (via Ollama) to convert natural-language inputs into structured expense entries, enabling single-step data capture.
Star-Schema Data Warehouse (SQL, ETL)
- Designed a star schema (fact/dimension) for a recommendation dataset.
- Automated daily CSV loads via scheduled SQL jobs (ETL).
