AI & Data Engineer
I build AI applications and the data pipelines that support them—from transaction classification and retrieval to Python services on AWS.
My work connects model evaluation, reliable data processing, and repeatable cloud deployment.
Data pipelines, analytics and applied ML.
Data pipelines and analytics
Independent projects. Practical questions.
Personal finance, made understandable.
An AI personal finance assistant that classifies transactions, forecasts monthly spending, and grounds budgeting recommendations in each user’s transaction history.
Built the TensorFlow classification and RAG workflows, orchestrated Plaid ingestion, and managed Python services and MLOps delivery on AWS.
A LangGraph supervisor coordinates customer-support agents, combining specialist responses with retrieval and SQL tools.
My contribution — Integrated Amazon Titan Embeddings V2, pgvector on Amazon RDS, and SQL correction through schema mapping and few-shot examples.
RAGAS context precision improved from 0.52 to 0.91 on a manually curated 50-pair evaluation dataset.
The supervisor coordinates order-management, recommendation, troubleshooting, and personalization services. Amazon Titan Embeddings V2 and pgvector on Amazon RDS support retrieval.
Schema mapping and few-shot SQL examples guide query correction. Evaluation against a manually curated 50-pair dataset measures retrieval context precision, which improved from 0.52 to 0.91.
Combines sentiment extracted from support logs with an XGBoost classifier for customer churn prediction.
My contribution — Used the DeepSeek API for zero-shot sentiment extraction across 150,000 customer profiles and fed the extracted features into XGBoost.
Independent project using a public dataset, separate from client work.
Classification, forecasting, and retrieval-grounded applications, with model evaluation and experiment tracking.
Batch and streaming ingestion, dimensional modeling, SQL transformations, orchestration, and data quality.
Python APIs, containerized workloads, and repeatable AWS delivery through infrastructure and automated checks.

04 / About
I’m Mahmoud, an AI and data engineer in Cairo. I work across the pipeline, the model, and the cloud deployment.
Freelance work with e-commerce and telecom clients shaped how I deliver: validate the data, document the system, and leave a handover the client’s team can operate. My independent projects explore classification, retrieval, and AI orchestration.
