Mahmoud Chaer

Undergraduate Researcher at AUB. I worked on privacy-preserving AI systems for enterprise LLM applications, focusing on protecting sensitive information before prompts reach language models.

I developed DomainShield, a benchmark and evaluation framework for sensitive-entity masking, and explored retrieval-augmented techniques to improve privacy while preserving task performance across domain-specific enterprise prompts.

The project culminated in a research paper on LLM security and privacy-preserving prompt processing, where I served as a co-author.

Software Engineer at Murex. I continued on the MX.3 Viewer team part-time during my final year at AUB, building and optimizing performance-critical C++ backend components.

I also extended a Viewer Recorder and Replayer framework for deterministic event capture and replay, so hard-to-reproduce issues can be inspected with less guesswork.

Teaching Assistant at AUB. I helped teach Python programming and algorithmic thinking for EECE 230, supporting more than 100 students through labs, debugging sessions, and structured exercises.

This was also where I learned how much clarity matters: a small explanation can unlock an entire problem for someone.

Computer and Communication Engineering at AUB. I am completing a B.E. in Computer and Communication Engineering. My interests cluster around machine learning, agentic systems, numerical computing, backend software, databases, and systems design.
